can vouch for Siedhoff 10/10. he's a damn good doctor. one that cares, one that's extremely skilled, one with tremendous empathy and communication skills

Highly recommend siedhoff! He can’t treat lung endo himself - he will refer you to thoracic surgery (I have diaphragm endo and this is what he did for me at least)

Dr Siedhoff at Cedars. Best of the best. Most empathy out of any doctor I’ve ever met. Meticulous surgeon and takes excellent notes. I’ve never felt that any doctor cared about me until I met him.

Stage 4 also with siedhoff! Best doctor I’ve seen in my entire life and a meticulous, empathetic surgeon. I can’t recommend him enough!
r/r/Endo Feb 11, 2025 +2 pts
Truly, the best ever. I’ve never met a doctor with more empathy and more knowledge (and humility!) than Siedhoff. He genuinely cares about his patients and it shows. He responded to one of my messages at 12 AM on a Saturday… (a Saturday!!!) he cares THAT much. To be fair, I will say that his office can be a bit disorganized because they are so busy. The wait times are long to get in as a new patient, and some of the care coordination postop could’ve been better. But his staff is BUSY and doing their best. I would go so far as to say that even despite a few minor annoyances with his staff/scheduling, he is the best surgeon on the West Coast He is literally an angel among endo surgeons, I can’t recommend him highly enough. (ps I’ve heard great things about Dr. Wright too!)
r/r/Endo Oct 2, 2025 +1 pts
Apparently the reason surgeons want to remove the cervix is bc endo is likely to grow back there. personally I think it’s worth a shot to keep as much of it as possible. The way siedhoff explained it to me is that he tries to balance recurrence vs symptoms - so he doesn’t leave 100% of it he takes enough to balance the risk. I’m pretty sure he could handle a surgery to remove it later if needed. I will also say that he referred me to pelvic floor physical therapy after my first surgery and recommended things like acupuncture, consulting with a dietitian, pain management, urogyn, a whole list! If you ask for a referrals he will give you pages lol. I’ve never talked to Dr Orbuch but I’ve heard great things. It’s helpful to hear a different perspective, so I appreciate you for sharing. I wish I could weigh in but I’m clearly a little biased :)

I just wanna say that having anxiety over your health or “health OCD” as you call it is totally normal. How are we not gonna overthink things when we’re in pain all the time and dealing with crazy hormonal changes?? please go easy on yourself. it is not easy managing a full body chronic illness! what if it isn’t ocd, and instead it’s a perfectly healthy response to having a devastating illness? I would highly encourage you to seek out a second opinion from a different specialist. I am also in LA and I haven’t heard a thing about USC’s endo surgeons. It’s wonderful that you two have a strong relationship, and that she’s being proactive in monitoring things, however an expert would not tell you that you definitely don’t need surgery. That is something an untrained OBGYN would say. Has she referred you to pelvic floor physical therapy, a nutritionist, acupuncture, pain management, urology, GI or a fertility specialist? Endo is a full body disease and you deserve a comprehensive care team. If she’s not telling you about these things that’s another red flag. I cannot recommend Cedars minimally invasive gynecologic surgery team highly enough. Dr Kelly Wright or Dr Kacey Hamilton. Cedars does work with most insurance. The celebrity endo surgeon in LA is Dr Matthew siedhoff - he recently went private and he’s truly the best of the best endo experts in Los Angeles (and potentially on the West Coast). Depending on your insurance, the majority of the surgery will be covered in network (operates at cedars and St. John’s in SM) except for his professional fees which will be out of network. The fact is that laparoscopic excision surgery with a true expert (an OBGYN with additional training - typically a 3 year fellowship in minimally invasive gynecologic surgery - and performs dozens of excision surgeries a week) is the ✨gold standard✨ for diagnosing endometriosis. I was anxious as all get out for years…and that’s because something deep within me knew that I wasn’t getting the full story from my doctors. Please keep advocating for yourself and get a second opinion.

It went really well 😊 He found extensive stage IV endometriosis (27 pathology-confirmed samples). It was a complex case involving multiple areas. He worked alongside a cardiothoracic surgeon for diaphragm endo and they removed 8 lesions there. A GI surgeon was also present and participated, and Dr. Siedhoff coordinated all of it. Having that level of multidisciplinary planning in place made me feel very safe going into surgery. Before surgery, I hired a concierge vascular consultant to provide guidance on how to approach my pelvic congestion syndrome, since I also have MTS and NCS and the anatomy is complicated. Dr. Siedhoff read the entire 22-page report, and his operative notes clearly reflect alignment with those recommendations. That meant a lot to me. What stood out most wasn’t just the technical skill or the detailed documentation. It was how thoughtful and coordinated everything felt. For those of us who’ve spent years being dismissed, that level of thoroughness matters. On the human side, he checked on me every single day in the hospital. Seven days post-op, I panicked because my bandage got wet on Valentine’s Day of all days 😅. He texted back within an hour with clear instructions. I never felt brushed off or minimized. His entire team has been kind and respectful from start to finish. Even small things, like a little pre-op goodie bag, made a hard experience feel more supported. I know every case is different, but I felt listened to, taken seriously, and operated on carefully. After years of “it’s probably IBS,” that meant everything to me. TLDR: Really positive experience 😊 Complex stage IV case with diaphragm involvement, multidisciplinary team involved, and he even incorporated an outside vascular consult into the plan. I felt safe, heard, and very well cared for.

Dr. Siedhoff was incredible! He was very easy to talk to and seems to genuinely care. He knew right away what he wanted to do, and he gave me a 20 page packet at the end of the visit with FAQs and next steps. His office is extremely efficient, and he was kind enough to start a chat in the patient portal so that I could message him at any time. Overall an amazing doctor who I feel confident in, for once lol. The only downside is the wait, but if you can get in to see him, I highly recommend! Best of luck :)

Finally some good news! Finally some good news! I finally got in to see a minimally invasive specialist, Dr. Siedhoff in Los Angeles last Friday! He was incredibly kind and spent a lot of time prior to meeting with me to review my history. He made sure that I was able to ask questions and he was very attentive to detail. I had my first ever lap done in late March, and his exact words were that my endo was “incompletely treated surgically.” I have never felt so validated by a doctor, and he took my pain extremely seriously. He set me up and I will be getting a second lap done sometime this month. It’s unfortunate that I do have to have two laps over the span of four months, but I’m confident in Dr. Siedhoff and I’m looking forward to feeling better :)

I had initially requested a consult with Dr. Wright in September 2023, but I was put on a 5-7 month waiting list. I was able to get in contact with a Cedars representative in May, and they told me I could see her in August. I then requested to see Dr. Siedhoff, and the representative communicated with the office regarding my case, and I was able to get bumped up and saw him on June 7th, and was immediately scheduled for surgery for July 9th!

1 week out from my second lap in the span of 4 months 1 week out from my second lap in the span of 4 months Hi all, I am now 1 week out from my second lap, my first was on March 21,2024. I was wondering if anyone has experience with 2 laps in a short period of time, and how their experience was. I will be having surgery with Dr. Matthew Siedhoff, an endo specialist with Cedars following an inadequate surgery with my GYN. His plan is to do a presacral neurectomy and possibly do an appendectomy. I’m definitely more nervous this time around as it seems like a more intense lap than the first one (which was probably around 30 minutes) and I’m also worried about how my body will recuperate after having so much done in such a short amount of time. Any and all advice is appreciated! 💕

Positive Surgery Update!! Positive Surgery Update!! After one botched lap in March, I finally had a positive experience with a renowned endo surgeon, Dr. Siedhoff in LA this past Tuesday! I underwent a 2 hour surgery and Dr. Siedhoff and his team were incredibly thorough, excising endometriosis of the bladder, rectum, and uterosacral ligaments. I have been steadily improving each day, and I am hopeful that I will be feeling better for the first time in my life. 💛 I highly recommend Dr. Siedhoff and his MIGS team- they are truly life changing. 💖

I am with UCLA Health as well for my regular GYN, and I love them! Dr. Siedhoff and his group are amazing, and I actually was able to get scheduled for surgery 1 month after my first appointment with him. He was very understanding and genuinely listened to me, and was very confident that surgery would alleviate my pain so he scheduled me as soon as he could. I highly recommend him and anyone in his group! Thank you for the well wishes and I hope you find the right doctor for you and you feel better soon!💖💖
Patient 4 Had Surgery Positive 5 posts diagnostic laparoscopy / excision surgery with Dr. Siedhoff (April 2024)

“Felt truly wonderful after surgery. Persistent sciatic pain (decade-long) relieved immediately upon waking from anesthesia. Lost allergies, reduced body inflammation, better sleep, more energy, sex no longer painful, anxiety nearly gone. 4 months post-op feeling much better. First 3 post-op periods were heavy and prolonged (8-10 days) but improving. Constipation and gas pain lasted ~4 days post-surgery. i felt so respected by Dr Siedhoff at all times, which is enough to make me cry after so many”

half rant, half question half rant, half question sorry in advance for the long post! i’m looming for advice on picking a diagnostic lap provider i’ve been approved for my first lap and i’m so relieved! my obgyn who diagnosed m has been extremely validating, super knowledgeable etc., and is able to do the lap herself. she will have a colorectal surgeon and a urological surgeon with her should anything related to the organs they treat be on the complicated side. she was very clear that she would leave anything really complex and refer me to a surgeon with more expertise and tons of experience to excise further. my hesitation: she’s not an excision specialist. is it worth waiting months for a specialist? i’m going back and forth because this is technically a diagnostic so i was expecting to have more than one surgery anyway, but now i’m thinking that i may be able to get just one if i get the diagnostic with a specialist. i’m so upset that this is something i have to decide on- whether to wait for a specialist for ~6 months (in agony) or to trust my obgyn who doesn’t have as much experience some things to note: 1. my obgyn performs 10-15 laps per year and has 5 years of experience performing them. she’s young and has been a doc for 7-8 years 2. she’s upfront about knowing her limits which i appreciate 3. she works at the same hospital as multiple nook surgeons (Dr. Aliabadi & Dr. Matthew Siedhoff, Cedars Sinai in LA) and has assisted them in excision surgeries. i could wait for Siedhoff but it would be 6 months at least 4. my obgyn could perform surgery within a month 5. she’s brilliant and i trust her a lot 6. she has performed ablation for lesions on the uterus. she agreed to not perform any ablation on me and much prefers excision. but still…!! 7. i am in excruciating pain every day. i’ve been struggling with undiagnosed endo for 16 years and have had it significantly interfere with my life (need to work from home, had to pull out of school for a year to tend to my health, etc.). it essentially controls my life. it’s been much worse lately since i stopped hormonal birth control in Oct 2023 to try to figure out my hormonal imbalances. this led to discovery/diagnosis of endo 8. she’s a minimally invasive gynecological surgeon but has not completed the MIGS fellowship has anyone had a negative experience with someone who is experienced but not as experienced as others? is it silly to go into this expecting to have another lap? is it worth waiting months in agony for a nook doctor? would i be taking a gamble on my health by trusting my obgyn? ahhhh

hi! how was your experience?! i hope you got the relief you were hoping for! i’m getting my lap at cedars in 2 weeks with dr siedhoff. do you have any notes about your experience, and do you happen to remember how much your insurance was billed?
r/r/Endo Jun 24, 2024 +2 pts
this is so exciting! i had an amazing experience with Dr Siedhoff and the whole surgical team. i was also told 4 months but it ended up being 6 weeks! i hope your wait time has decreased. i chose a later date at the hospital vs a sooner one at the surgical center just because i was nervous but i would have been totally fine at the surgical center. i feel truly wonderful after surgery. i’m at almost 10 weeks post op now. i had persistent sciatic pain for about a decade before surgery and i felt the pressure released as soon as i woke up from anesthesia. of course there was other pain from just having tons of endo cut out but the lack of pain in my lower back was seriously immediate. recovery was fine. i couldn’t do much for myself for a few days so i definitely recommend having someone with you at all times for at least 2 or 3 days. you wont be able to get up to use the bathroom on your own and it helps to have someone give/make you food and remind you to drink water etc. the constipation and gas were horrible but that pain only lasted about 4 days. the best tips i have are to drink tons of water, take the gas and constipation relief stuff, walk as much as possible (helps loosen things up), sleep as much as possible, stay well fed, take your pain meds on time (don’t wait until you desperately need them), and have plenty of tv/movies ready to watch. i had a bunch of books but didn’t really feel up to reading them right after surgery. i had face wipes, body wipes, floss, mints, dry shampoo, and some other products like that right by me and that was super helpful in making me feel more hygienic lol. the “Lap Survival Guide” in this sub was super helpful too. i got overnight pads which were super helpful. i also got a peri bottle which i didn’t end up needing but i recommend getting one just in case. if you don’t mind them, i highly recommend period underwear for after the first few days. i found some Hanes ones on Amazon in juniors sizes (16 was like a womens small) for heavy flow and they were so cheap and good! the absorbent part covers the whole butt so they’re really great. you could also use these with the pads for the earlier days since the coverage is so large, but i bought and used (regular) womens boxers in a size up and they were great. i also used all of this again for my last 3 periods because they were super heavy and lasted 8-10 days each (mine were usually 5-6 before). they weren’t that painful though. i think this is the norm for post-op periods but not totally sure. i noticed an increase in energy right after recovery. i’ve lost allergies, my body is no longer inflamed, i sleep better, have more energy as i mentioned, sex isn’t painful, and my anxiety (which was truly crippling for the past 8 years) is almost gone. this surgery improved my quality of life so much and i wish everyone with endo could get it!! also, i found that Cedars is super easy to deal with! they were really great with billing and even refunded me some of what i paid. their “responsibility calculator” was 100% accurate. they didn’t have this specific surgery as an option but i just chose the other MIGS listed which worked. also, the social worker i was assigned on surgery day was awesome and helped a lot with any day-of questions and jitters. i hope you have a successful operation!! good luck! i probably missed some stuff here so please feel free to ask more questions :)
r/r/Endo Jun 25, 2024 +2 pts
he did! he checks everything. if you want a soecifix area checked, mention it to him or his assistant surgeon when they come to see you before surgery. thankfully he didn’t have to bring anyone else in (surprising because we were pretty sure there would be endo on my bladder and bowels but there wasn’t), but a colorectal surgeon and urological surgeon were available if they were needed. Dr. Siedhoff assured me that this would be the case no matter the location, but I was just so anxious about everything and felt reassured by being in the hospital with its many resources vs. a surgical center. this was totally a personal decision and only based on my own feelings so don’t out much stock in it! if i did it over, i’d take the earlier appt regardless of location

hi!! actually going to respond here in case it helps anyone else in the future :-) my experience was truly amazing. i felt so respected by Dr Siedhoff at all times, which is enough to make me cry after so many years of feeling unheard by doctors. his team is amazing both in regards to their professional experience and skill and their kindness and great bedside manner. if you go with him, they will be your main point of contact. *i’m typing on my phone so i apologize for any typos* here was my process start to finish: - december 2023: i discovered that i most likely had endo - january 2024: called the MIGS (minimally invasive gynecologic surgery) group at Cedars Sinai and requested Dr Siedhoff, because of info from reddit users. the Orbuchs who are both at CS too are also very highly regarded, but they didn’t sound particularly friendly or comforting which was super important to me. they have talk to a scheduler who will help set up a callback from the doctor’s office. i was called back within 3 days and was then able to provide info on my history - February 2024: i met with Dr Siedhoff virtually who had already reviewed my info (i feel like everyone should do this but they don’t so it made a difference to me!) and he agreed to operate on me. he informed me of all of the associated risks and answered my million questions about patient outcome, recovery,continuing care, etc. - a surgical scheduler reached out to me with two date options for march and april! i thought i would have to wait months and months but my surgery was scheduled only 6 weeks in advance. i was floored by this, but i think it’s normal because he only performs surgery and is not an obgyn otherwise. so his time is almost fully devoted to operating - march 2024: i had a pre surgical visit with his PA about 10 days before my surgery and had a chance to ask her more questions. she explained exactly what would happen, from arriving at the hospital through recovery - april 2024: i had my surgery! i got to the hospital, was checked in, and was introduced to my assigned social worker. she was there for any questions i had about anything that would happen at the hospital. i ended up having no questions at all because they’d all been answered, but it was still nice to have her. in pre op, each one of the surgical staff came to speak to me individually. they each explained what they would do and answered any questions i had. one in particular came from Israel just to work with Dr Siedhoff, which is not at all surprising to me after having experienced his work. when it was time, i was taken into the OR and helped onto a table where i was anesthetized and obviously operated on lol. it took 4hrs which was longer than the quoted time but not bad at all. right after surgery, Dr S called my husband who was in the waiting room and told him that he found endo and everything was successfully removed. i was in recovery for about 2hrs total including the time it took me to wake up. i was discharged soon after. everything was done in a timely manner and was so smoothly executed. Cedars is so awesome. i went home that day and was mostly bed bound for the next 2 days and then started to be able to move around better. i got my pathology report a few days later, then had my followup with the PA about a weekish later. i’m now 4 months post op and feeling soooo much better!! here are some things you should know if you choose to be operated on in general: - make sure you have someone to take you to and from surgery and to stay with you for the first 2 days of recovery. if no one can stay with you, make sure to prep your recovery space with everything you may need. you’ll also have to use the “pull your knees into your chest and roll to the side” method of getting out of bed because it’ll be hard to get up on your own - try to only take the painkillers for as long as you reeeallly need to- the pain from constipation is honestly almost as bad as the surgical pain so the sooner you stop and are able to poop, the better! - your first few periods will suck and you might feel discouraged. my first 3 were awful but the most recent one wasn’t so bad. they should get better each month - recovery takes longer than you may think. initial recovery takes anywhere from 2-6 weeks, but full recovery takes about 6 months. it may be minimally invasive, but your insides are cut up in areas that are already inflamed and that all takes time to heal. i think this has more to do with location than with amount of endo, but i’m not sure please ask any questions you may have! i hope this was helpful and that you get the treatment you so deserve💞💞💞

Seeing horrible reviews of my surgeon and my lap is in 4 weeks! Seeing horrible reviews of my surgeon and my lap is in 4 weeks! Hi, as the title suggests, I decided to do some research on my surgeon as I’m having my pre-op appointment for my surgery in December when I came across alarming reviews. Although many people have said Dr. Siedhoff is an incredible surgeon, I’ve seen SO many, and I mean A LOT of scary reviews and I’m panicking. People saying their nerve in their bladder was damaged and they no longer can urinate properly, someone had internal bleeding and when their stitches accidentally popped, he suggested a bandaid. I’ve seen people say they wake up in severe pain from surgery. And now I’m FREAKING OUT. What do I do?! I waited a year for this surgery 😭

I just had my pre-op visit with Dr. Schneyer who I really admire. I asked her about the bad review and she told me that of course, anything could happen but statistically, it’s around a 1% chance for anything like that to happen. She said her and Dr. Siedhoff are quite thorough in making sure everything is homeostatic and everything is good. She’s quite optimistic in their approach so I’m sure everything will be alright. I hope all goes well for you, sending lots of positivity 🩵🩵🩵

12 years later… 12 years later… Yesterday I had my laparoscopy and excision with Minimally Invasive Gynecologic Surgeons and officially got diagnosed with endometriosis. Here’s my story for anyone undiagnosed but suspecting, and/or waiting for their lap: Starting at 14 years old it began bloating and lethargy to then dealing with unmanageable chronic pain as well as other horrific symptoms throughout these 12 years. I had gone through: 5 specialists (GI, Endocrinology, etc.) 2 endoscopies, 1 colonoscopy, countless ultrasounds, an “endo” ultrasound, countless MRIs, several CT scans, multiple ER/Urgent care visits and an insane amount of blood tests later and no a laparoscopy and excision to be officially be diagnosed with Endometriosis. I had several excisions take place yesterday, including a subcentimeter rectovaginal lesion (endometriosis) being removed and from a quick online search it states, “Rectovaginal endometriosis (RVE) is one of the most severe forms of endometriosis, and is considered stage 4 according to Kirtner's classification. It is much less common than ovarian or peritoneal endometriosis and affects between 3.8% and 37% of all patients with endometriosis.” Why am I sharing this in such detail? Because this is the story of resilience, advocating for yourself, and TRUSTING your mind’s intuition and physical indications. For any of you out there questioning your experience and your pain, this is what my (female) gynecologist of HALF A DECADE told me prior to me seeing my Minimally Invasive Gynecologic Surgeons, “You don’t have endometriosis, and I’m not even bothering sending you to a specialist for them to say the same thing and waste everyone’s time. Your pain is normal”. That was the last I saw her. Please, do not stop seeking answers even when the tunnel seems dark and never ending. I’ve dealt with mental and physical pain for almost half my life but am proud of myself for continuing to push through, advocate, and fighting to not be known as the disease I did not choose to have. With that being said, I always knew being a doctor was the route I wanted to take, but it wasn’t until I began being gaslit and pushed aside by medical professionals due to their lack of knowledge and research of the human body. And with that being said, I am forever grateful and inspired by my surgeons: Attending Surgeon: Dr. Siedhoff Fellow: Rebecca Schneyer, MD Resident: Anne Lyon, MD and of course my incredible Anesthesiologist: Poudlar, Tiffany Mounes, MD *Might I add the best experience waking up from anesthesia and was told how much anesthesiologists matter in recovery from general anesthesia. Notice the all female team (excluding my wonderful attending)? True heroes dominating a primarily male field (which I was told is becoming more female dominated. So don’t give up, there’s always a light even if it might not seem like it.

Important Thoughts to Share w/ Anyone Waiting for a Diagnosis Important Thoughts to Share w/ Anyone Waiting for a Diagnosis A couple days ago I posted how I went into my laparoscopic surgery with excision thinking I woke up w/ a diagnosis only to be told it was inconclusive until pathology came back so, I deleted my post. I was told there were biopsies taken but the most convincing one was superficial and fell apart while excising which is abnormal for endo. I broke down in tears, so nervous my pain and surgery was for nothing until today, all my biopsies came back benign, minus that suspicious spot that then came back as endometriosis. Why am I sharing this? Starting at 14 years old, what began as bloating and lethargy then progressed to unmanageable chronic pain as well as other horrific symptoms throughout 12 years. I had gone through: 5 specialists (GI, Endocrinology, etc.) 2 endoscopies, 1 colonoscopy, countless ultrasounds, an “endo” ultrasound, countless MRIs, several CT scans, multiple ER/Urgent care visits and an insane amount of blood tests later and a laparoscopy and excision to be officially be diagnosed with Endometriosis. It took months of research, calling for cancellations, and waiting almost a whole year for my surgery to take place with a reputable surgeon. Advocating for yourself, and TRUSTING your mind’s intuition and physical indications is key for searching for any answer. For any of you out there questioning your experience and your pain, this is what my (female) gynecologist of HALF A DECADE told me prior to me seeing my Minimally Invasive Gynecologic Surgeons, “You don’t have endometriosis, and I’m not even bothering sending you to a specialist for them to say the same thing and waste everyone’s time. Your pain is normal”. Now, how did this small lesion that weakly fell apart cause so much pain? To be honest, no one really knows. However, what’s important isn’t the diagnosis nor the science behind it at this point because it’s surrounded by a whole lot of theories. I just want everyone in this Reddit to understand whether it’s endo, hormonal autoimmune conditions, or even undiscovered scientific issues, it’s important to listen to your body and to balance your exposure to the internet while trusting medical professionals too. An insane task to ask anyone to do, I know. But I am beyond grateful for this Reddit, for all the advice ever given. For the doctors everyday sacrificing their lives for people like us. For the surgeons currently researching and working on solutions endo and non-endo related. I’ve dealt with mental and physical pain for almost half my life but am proud of myself for continuing to push through, advocate, and fighting to not be known as the disease I did not choose to have. With that being said, I always knew being a doctor was the route I wanted to take, but it wasn’t until I began being gaslit and pushed aside by medical professionals due to their lack of knowledge and research of the human body.

Is this crazy to suggest to surgeon? Is this crazy to suggest to surgeon? I’m meeting with an excision specialist next week. I have had this scourge (endo) for probably 25 years now. I was in a ton of pain previously but somehow got pregnant with twins in 2017 but after the c section it’s next level awfulness. Before I didn’t know much about endo now I am aware that my left ovary is adhered to uterus which is adhered to bowel. I have severe rectal pain with BM’s sometimes randomly. I can feel tugging and pulling in my right side when I use that oblique. I also have incision pain from c section scar and lumps in the scar. Bottom line: I believe it’s everywhere. I also have psoriatic arthritis and tend to keloid and not heal well in general. Can I ask the surgeon to just go in through the c section scar or is that just bananas and a terrible idea? My stomach has been through so much...I don’t want 5 holes in plus I have a deformed c section scar already. I guess my tissue atrophied and I have a huge dent. If that area is already messed up why risk more adhesions? I don’t know. I just know those holes will keloid and That my abs wont ever be ok after a lap. I figure no matter how they get in there it will be two months before I can even feel somewhat ok again. This is vain on some level I’m acknowledging that but I also keloid and honesty don’t heal well at all. My issues are around that scar anyway I figure why disturb tissue higher up? Siedhoff is my doctor theoretically. I read online (fb endo support groups) he’s nicked the bowels of at least 2 people so obviously I have a lot more to worry about than disfiguring keloid scars all over my stomach. Thanks for reading.

Find a specialist. You don’t. Need to lose your last ovary. Some of these doctors are like illegal chop shops. I used dr. Siedhoff in La he takes insurance to see him don’t let some sub par hack mess you up permanently.

it's not the right surgery and the surgeon is clearly not skilled enough to do it. She needs to find a specialist. That's the dumbest thing I've ever heard of, I say that not to be disparaging to OP, but to the surgeon. Thy think they can play around inside our bodies? Um no, that would cause so many more problems for her. Losing ovaries opens you up to so many more issues, I had all my lesions removed and I don't have any issues now really. Dr. Siedhoff did it and he takes insurance. BTW estrogen without progesterone makes the lesions come back even worse, I'm legit scared for op cause her doctor is literally stupid or something. This is a real disease that affects people, it's like no one takes it seriously even doctors that specialize in this? I cannot for the life of my figure out why she would say that, it's bonkers. Estrogen dominance is what causes the fucking lesions. Well xenoestrogens. I would take dim with bioidentical progesterone cream until you find someone better. This person will for sure increase your problems and your misery, and I can't imagine someone that dumb is going to perform a technically perfect surgery, you got a lot of nerves and things "down there" that's a hard pass. Love them a 1 star review so everyone knows to steer clear.

man that sucks im sorry. I've had people flip on me for saying I don't have it anymore. My surgeon was just THAT good though. Dr. Siedhoff btw, I got lucky he lives where I do and took my insurance. I also had clean up injections of ozone in my pelvic cavity and bladder and that worked really well I think with any residual pain or symptoms.

“Surgery went longer than expected (~5 hours), kept overnight. Removed endometrioma on ovary, endo on bladder, peritoneum near liver, rectum and uterus, large nodule adhering uterus to rectum. Called in colorectal surgeon. Performed presacral neuroectomy and appendectomy. Good bedside manner, kept husband informed. Patient was hopeful about outcome. Dr. Siedhoff is confident about the outcome of surgery. I've lived with so much pain the last 10+ years and am so happy to begin the healing process.”

Expert Endometriosis Excision Surgery in Los Angeles: Success Story! :D Expert Endometriosis Excision Surgery in Los Angeles: Success Story! :D I had endometriosis excised by Dr. Matthew Siedhoff at Cedars Sinai in Los Angeles in August 2017. The surgery went longer than expected (about 5 hours), and they kept me overnight at the hospital. Dr. Siedhoff is confident about the outcome of surgery. He removed an endometrioma on an ovary, endometriosis on my bladder, endometriosis on the peritoneum near my liver, endometirosis on my rectum and uterus. Apparently my uterus and rectum were glued together with a large endometriosis nodule (Stage 4). He called in a colorectal surgeon to assist in separating the organs and removing all endometriosis. I went into the surgery only knowing that I might have endo because my cyst looked like an endometrioma from previous ultrasounds. Dr. Siedhoff sent samples to pathology. When Dr. Siedhoff got the pathology report, he confirmed everything he removed had endometriosis. He also evaluated and removed my appendix, cut one of the nerves to my uterus (presacral neuroectomy), and evaluated the inside of my bladder. The nurses and care partners were so kind, along with the anesthesiologists. Dr. Siedhoff also had great bedside manner and kept my husband in the waiting room apprised of any changes. I've lived with so much pain the last 10+ years and am so happy to begin the healing process. I recommend requesting to join the Nancy's Nook Endometriosis Discussion and Education Facebook group. They have files detailing the research of why endometriosis surgery via excision has better outcomes (versus ablation/fulguration: essentially cauterizing or burining the disease off). Endometriosis surgery via excision can have a 20% or less recurrence rate (from any missed disease, not from re-growth). There are also studies showing that 60% of women trying to conceive after endometriosis surgery via excision were able to conceive naturally within 12 months after surgery. It's been a long journey for me, and now I see the light at the end of the tunnel.

I’m so sorry you’re having to potentially have a second surgery. For me, the main difference with going to the CEC was the PRP therapy and one other thing, I forget what it was called, some sort of synthetic amniotic fluid like membrane that they put in place in an area that was highly operated on. They do spray the PRP all over the area inside the abdomen at the end of the surgery, to coat everything with it, from what I understand. I also think GA at the time was a bit less concerned about what medication they could prescribe, so they were a bit more liberal about giving me pain medication in the hospital. I essentially had a pain pump that night in the hospital and that was nice. Dr. Sinervo thought at the time that my case was a bit complex for Dr. Siedhoff, but that’s already 8.5 years ago when I had my first surgery. I had a recent MRI with the endo protocol and it doesn’t show any noticeable endo.

The amniotic membrane and PRP are really why I went to the CEC. I had suspected the recurrence of endo around the bowel after my first surgery but also suspected adhesions. I really wanted anything to help prevent adhesions for a second surgery. Not sure which doctors use which strategies, but the CEC seems to keep track of many of the strategies. It would be good to know if Dr. Siedhoff uses any of these. https://www.centerforendo.com/adhesions

My doctor is Dr Siedhoff. My surgery is scheduled for the fall (by choice— once you have an initial visor his surgery wait time is about 6 weeks). I had to wait three months for my initial visit, though. So far I really like him and all my doctors and physical therapists spread really highly of him.

No, my doctor is Dr. Siedhoff. But I have heard really great things about Dr. Wright and Dr Truong too. I think they are all great.

“UPLIFT procedure performed for retroverted/retroflexed uterus. Patient went from unable to walk to kitchen to walking almost 5 miles. Completely off all pain meds post-op. Procedure described as very minimally invasive and 'made a world of difference'. Still has some issues. I still have issues but the procedure is very minimally invasive and made a world of difference. I went from not being able to walk to the kitchen to stand and microwave a meal to walking almost 5 miles last weekend.”

Omgosh yes that'd be great! I don't have a date yet, but I probably will be getting it. Are you going to Dr. Siedhoff or Dr. Wright?

My uterus was retroverted and retroflexed. I had so much intense pain this summer that I ended up having surgery to address it. The procedure my surgeon (Dr. Matthew Siedhoff) did is called the [UPLIFT procedure](https://www.docguide.com/clinical-study-demonstrates-inlet-medicals-uplift-procedure-reduces-womens-pelvic-pain-caused-tipped#:~:text=The%20UPLIFT%20procedure%20is%20a,on%20the%20day%20of%20surgery.). I'm completely off all pain meds now and take norethindrone 2.5 mg daily without stopping so I don't get my period. I still have issues but the procedure is very minimally invasive and made a world of difference. I went from not being able to walk to the kitchen to stand and microwave a meal to walking almost 5 miles last weekend. I also have suspected adeno. Previously dx with stage iv endo but no new lesions found at my latest surgery. Good luck and hope you feel better soon!

“Life-changing surgery. Patient felt substantially better within three days and continued improving. Recovery was easier and less painful than the endometriosis itself. Previous NOOK specialist had dismissed her based on normal-looking ultrasounds. I had to go to Dr. Siedhoff in Los Angeles to get taken seriously, and it turned out I have stage IV endo all throughout my abdomen and pelvic cavity. Only the most recent one was with a specialist (Dr. Siedhoff and his team at Cedars Sinai, if it matt”

Yes. I did/do, and actually got blown off by a NOOK specialist because the ultrasounds all looked normal. I had to go to Dr. Siedhoff in Los Angeles to get taken seriously, and it turned out I have stage IV endo all throughout my abdomen and pelvic cavity. Ultrasounds are useless for endometriosis.

I'm a nightmare scenario stage IV (thoracic involvement, clinical obliteration of several interior abdominal and pelvic surfaces, separation of my abdominal wall, bowel resection, nearly lost a kidney, etc). I've had several excisions. Only the most recent one was with a specialist (Dr. Siedhoff and his team at Cedars Sinai, if it matters), and it made an absolute world of difference. I would do it again in a heartbeat. It changed my life. Recovery was easy and less painful than the actual endometriosis. I felt substantially better within three days, and just kept feeling better and better as the days went on. One thing I would recommend is frequent routine exercise in the aftermath of the surgery (even if it's just walking). I cannot overstate the positive effects of physical activity for pain control. I didn't really make an effort to exercise after my first couple of surgeries, and it made pain management impossible. I did for the most recent ones, though, and the difference was huge. Part of it is because I scar terribly (scar tissue from adhesions is a huge reason why I had so much trouble), but exercise keeps the scar tissue stretchy and limber. But I think it's effective and important in its own right. I know it's hard, but don't worry too much. It will go well, and you'll be so happy once you're healed up 💛
