Endometriosis Excision Surgery

Endometriosis excision surgery removes endometriosis lesions from their root to reduce pain, inflammation, and organ irritation—often with better long-term relief than “burning” lesions, which is known as ablation. It’s considered the gold standard surgical approach for many people with endometriosis.

Overview

Endometriosis excision surgery is a minimally invasive procedure that aims to remove endometriosis (endometrial-like tissue growing outside the uterus) rather than simply cauterizing the surface and hoping that the damage is deep enough to eradicate the endo lesions. The latter is called ablation. By removing disease more completely, down to healthy tissue below the lesions, excision surgery may offer more durable relief of symptoms like pelvic pain, painful periods, pain during intercourse, and certain bowel/bladder symptoms.


Absolute proof for excision in all situations has been elusive. For superficial endometriosis, both ablation and excision can improve pain in the short term. The challenge there is mainly whether or not the surgeon can correctly identify endo lesions, assess risk to nearby delicate structures like the ureters, and is able to determine that the disease is not actually deeper than they thought. This last part is hard to do when looking at the surface in all but minimal endo cases. However, for endometriomas and deeper disease, excision has stronger evidence for improved pain outcomes and reduced persistence/recurrence risk, and it allows tissue confirmation. Pathologic confirmation of endo supports accurate staging and leads to treatment decisions down the line that are not based on guessing what the diagnosis is.


Endometriosis can look and behave differently from person to person—superficial lesions, deep lesions, atypical looking lesions, scar tissue/adhesions, ovarian cysts (endometriomas), or even deeper disease affecting pelvic nerves, bladder, bowel, ureters, or diaphragm. Excision is designed to address endometriosis comprehensively and thoughtfully, while preserving healthy organs whenever possible. So it is not just a matter of excision vs ablation. It is a matter of surgeon experience in determining what, why, when and where to do what. Learn more about the condition itself here: endometriosis.


At Lotus Endometriosis Institute, excision surgery is part of a larger care plan that may include advanced diagnostic evaluation, pain-focused support, and integrative recovery tools. We generally go beyond routine evaluation to ensure the treatment plan is as well grounded as possible. You can explore our services and surgery and advanced excision to see how care is coordinated.

When Is It Recommended?

Excision surgery is commonly recommended when symptoms are persistent, worsening, or life-limiting despite medical therapy—especially when you’ve tried options like anti-inflammatory strategies, hormonal suppression, or targeted hormonal therapy but still have significant pain, fatigue, or functional limitations. It may also be considered when imaging or exam suggests endometriomas, deep disease, or adhesions that are unlikely to improve with medication alone.


It’s also an option when endometriosis is suspected but you’re stuck in the “maybe/unclear” stage—especially if your symptoms are cyclical and classic (for example: severe painful bowel movements, bladder pain, or urinary urgency that flares with your cycle). A specialist evaluation can help determine whether surgery is likely to be helpful, and what else should be considered. Start with evaluation and diagnosis.


For people trying to conceive, excision may be recommended to improve pelvic anatomy and reduce inflammatory burden—particularly if endometriosis is suspected to be contributing to infertility. Because fertility goals change surgical planning, it’s important to discuss your timeline and priorities early in the consultation.

What to Expect

The goal of excision surgery is to reduce pain drivers and improve quality of life—often by decreasing inflammation, releasing organs that are “tethered” by adhesions, and removing endometriosis lesions that irritate sensitive tissues. Many patients report meaningful improvement in period pain, daily pelvic pain, bowel/bladder flares, and pain with intimacy, although results vary based on disease location, coexisting conditions, and how long pain has been present.


It’s equally important to know what excision surgery doesn’t do: it doesn’t guarantee complete or permanent symptom elimination, and it may not address every contributor to pain (for example, pelvic floor muscle spasm, nerve sensitization, IBS-like symptoms, bladder pain syndrome, or adenomyosis). Lotus integrates supportive care such as pain management, integrative medicine and lifestyle care, and pelvic floor therapy to help your nervous system and muscles recover and to cover other possible related or unrelated pain generators. Endo causes a lot of problems but it usually does not directly cause all of them.


During your planning visit, you can expect a detailed conversation about your symptoms, goals (pain relief, fertility, avoiding hysterectomy, etc.), prior treatments, and what organs might be involved. If symptoms suggest overlapping conditions, your team may also discuss related diagnoses—such as adenomyosis or other issues listed under related conditions.

About the Surgery

Endometriosis excision surgery is typically performed using minimally invasive laparoscopy (with advanced robotic assistance in most cases at Lotus). Through small incisions, the surgeon carefully identifies endometriosis lesions and removes them with an excision technique—aiming to eliminate disease while protecting healthy tissue and organ function.


Because endometriosis can hide in complex areas (around the bowel, bladder, ureters, pelvic nerves, or diaphragm), the “scope” of surgery depends on what is found and what you and your surgeon agreed to in advance. Some patients also need treatment of associated problems during the same operation—such as removal of ovarian cysts/endometriomas, release of adhesions, or evaluation/treatment of suspected deep disease. (Those may align with procedures like Excision of Endometriomas, Pelvic Adhesiolysis, Bladder Surgery for Endometriosis, or Bowel Surgery for Endometriosis, depending on your case.)


At Lotus, surgery is approached as one part of a long-term plan: remove disease thoughtfully, confirm diagnoses when possible, look for other pain generators, and create a recovery strategy that supports healing and reduces the chance that symptoms persist due to untreated overlap issues. Learn more about the surgical approach here: surgery and advanced excision.

Recovery Expectations

Most patients go home the same day or after a short stay, depending on surgical complexity and individual needs. In the first several days, it’s common to have abdominal soreness, fatigue, bloating, and shoulder/upper back discomfort related to laparoscopy. Many people can do gentle walking right away, but you’ll want to plan for help with childcare, lifting, and household tasks early on.


A typical recovery involves gradual improvement over 2–6 weeks, but it’s not unusual for full “settling” of pelvic inflammation and nerve irritation to take longer—especially after complex excision or long-standing pain. Your team will give guidance on activity, incision care, bowel support, and when to resume sex, exercise, work, and travel. If pelvic floor tightness is part of your symptoms, pelvic floor therapy may be recommended after surgery to support lasting relief.


If you have ongoing symptoms after surgery, it does not automatically mean the surgery “failed.” It may mean you need targeted treatment for adenomyosis, pelvic floor dysfunction, bladder/bowel overlap conditions, or central sensitization. That’s why coordinated follow-up and a personalized plan through our services matters.

Why Expertise Matters

Excision surgery is highly skill-dependent. Endometriosis lesions can be subtle, hidden, or located near structures where precision is critical (ureters, bladder, bowel, pelvic nerves, diaphragm). A surgeon with advanced excision training is more likely to recognize the full pattern of disease, remove it thoroughly when safe, and avoid incomplete treatment that can leave behind active lesions or unresolved adhesions.


Expertise also matters for protecting fertility and organ function. Decisions like how to manage ovarian endometriomas, how to handle deep disease, and when to involve additional surgical support can affect outcomes—pain relief, recurrence risk, and complication risk. This is why many patients seek a specialist center focused on endometriosis rather than general gynecologic laparoscopy.


Lotus Endometriosis Institute is led by Dr. Steven Vasilev, known for being an early adopter and published leader in surgical complex-case care, including advanced excision surgery before the term MIGS was even coined. If you’re considering surgery—or you’ve had prior surgery and still have symptoms—you can schedule a consultation to review options and build a plan that matches your goals.

Patients Often Ask

What is endo belly?

“Endo belly” is the common term patients use for the severe bloating and abdominal swelling that can happen with endometriosis. It’s often described as a belly that looks or feels suddenly distended—sometimes within hours—and may come and go in waves, frequently worsening around a period but not always. Importantly, this can mimic weight gain even when the underlying issue is swelling, fluid shifts, or gastrointestinal distension rather than true fat gain.


Endometriosis can irritate tissues in the pelvis and abdomen and can also affect (or “talk to”) the bowel, which helps explain why many people notice constipation, diarrhea, cramping, or a tight, pressured abdomen alongside pelvic pain. You can have significant digestive symptoms even when routine GI testing looks normal, because endometriosis often involves the outer surface or deeper layers around the bowel rather than the inner lining.


If endo belly is a major part of your symptom pattern—especially when it comes with painful bowel movements, cyclical flares, or persistent pelvic pain—our team can help you sort out what’s driving it and what treatment options are most likely to bring relief. Explore our educational resources, and if you’re ready, reach out to schedule a consultation so we can review your history and build a plan around your goals.

What are signs endometriosis has returned after surgery?

Endometriosis “returning” after surgery can show up as symptoms that improve for a while and then gradually (or suddenly) come back months or even years later. The most common signal is the return of your familiar pattern—cyclical pelvic pain, worsening period pain, pain with intercourse, or pain that starts spreading beyond where it used to be. Some people also notice bowel or bladder symptoms re-emerge (pain with bowel movements, rectal pressure, urinary urgency or bladder pain), especially if those organs were involved before. New or increasing fatigue and activity limitation can be part of the picture, but the key is a clear change from your post-op baseline.


It’s also important to know that recurrent pain doesn’t always equal recurrent disease. Even after complete excision, the nervous system can stay “turned up,” and pelvic floor dysfunction, adhesions, or central sensitization can keep pain going or make normal sensations feel painful—so we think in terms of patterns, triggers, and timing rather than a single pain score. If symptoms are returning, our team can help you sort whether you’re in a true recurrence lane (improved, then returned) versus persistent pain that never fully settled, and decide when imaging (such as ultrasound or MRI) is useful—particularly for tracking ovarian endometriomas. If you’re noticing a shift back toward your old symptoms, reach out to schedule a consultation so we can build a clear, long-term follow-up plan with you.

Why do endometriosis patients try alternative medicine?

Many people with endometriosis try “alternative” medicine because they’ve spent years in pain without clear answers or durable relief. When hormones cause side effects, symptoms persist after prior treatments, or surgery feels out of reach, it’s completely understandable to look for something—anything—that offers a sense of control and day-to-day functioning. Social media and anecdotal stories can also make certain approaches sound like hidden “cures,” especially when the medical system has been dismissive or slow to diagnose.


We also see another, more practical reason: endometriosis pain is multifaceted—driven by inflammation, pelvic floor and musculoskeletal factors, nerve irritation, and sometimes central sensitization—so patients often need more than one tool. The key distinction is that integrative care is meant to work alongside mainstream medical and surgical treatment, not replace it. Our approach is to help you separate what’s promising and measurable from what’s expensive, vague, or marketed as a miracle, and build a coordinated plan that targets both the disease and the pain mechanisms that keep symptoms going. If you’re feeling pulled toward alternative options, we invite you to reach out—so we can help you make a plan that protects your time, your body, and your long-term goals.

How do I make the most of a short endometriosis appointment?

Go in with a one-page snapshot of your story so the limited time is spent on decision-making, not backtracking. The most helpful snapshot includes: your top 2–3 symptoms, the pattern (cyclical vs daily, triggers, where pain starts and spreads), what you’ve already tried and what happened, and what your symptoms keep you from doing (work, school, intimacy, exercise). If you have a history of “normal” scans, bring that too—because imaging can miss endometriosis, and the pattern of symptoms and prior response to treatment still matters.


Bring the right records if you have them—especially operative reports, pathology, and imaging reports (and ideally the actual images). Then decide your goal for the visit: diagnostic clarity, a plan to evaluate look-alike or coexisting conditions, or a clear surgical discussion (whether surgery is likely to help, anticipated scope, and what recovery may involve). If you want to make the appointment count even more, reach out to our team ahead of time so we can review what you’ve already done and tell you exactly what information would be most useful for a focused, productive conversation.

Can I keep working with endometriosis?

Yes—many people with endometriosis keep working, but it often requires a realistic plan around symptoms like pain, fatigue, brain fog, heavy bleeding, and unpredictable flares. Work becomes harder when endometriosis pain isn’t just “period pain,” but a complex, whole‑nervous‑system experience that can persist throughout the month and sometimes continues even after partial treatments. If your job performance is being affected, that’s not a personal failure—it’s a sign your symptoms need more targeted evaluation and a clearer strategy.


In our practice, we think about work in two parallel tracks: managing symptoms so you can function day to day, and treating the underlying disease when it’s driving ongoing inflammation, adhesions, or organ involvement. Depending on your situation, this may include a structured pain management approach (often multimodal) and, when appropriate, excision surgery planning based on a careful review of your history, imaging, and prior operative/pathology reports. If you’re wondering what’s realistic for you—whether that’s staying at work with accommodations, reducing hours temporarily, or planning time off for treatment—reach out to schedule a consultation so our team can review your records and help you map out next steps.

What questions should I ask an endometriosis specialist?

Come in focused on how your surgeon thinks and how your care will be mapped out. Helpful questions include: based on my symptoms and records, what diagnoses are you considering (endometriosis, adenomyosis, and common look‑alikes), and what makes you lean one way or another? Ask what additional records or imaging would meaningfully change the plan, and whether your imaging will be interpreted with endometriosis mapping in mind—not just a “normal/abnormal” read.


If surgery is on the table, ask for specifics about technique and scope: do you primarily perform excision (rather than superficial burning/ablation), and how do you confirm what was removed (photos, operative report detail, pathology)? Ask what areas you expect could be involved in your case (ovaries, bowel, bladder/ureters, diaphragm) and whether a multidisciplinary team is planned if those organs may be affected. It’s also reasonable to ask how they define surgical “success” for your goals—pain relief, bowel/bladder function, fertility—and how outcomes and recurrence/persistent symptoms are handled.


Finally, ask how the care process works from start to finish: what the pre‑op workup includes, what recovery typically looks like for the anticipated complexity, and how follow‑up is structured if symptoms don’t resolve fully. In our practice, we review records purposefully before meeting so the conversation is productive and realistic, and we’ll be direct about whether surgery seems likely to help or whether another path makes more sense. If you’d like, you can reach out to schedule a consultation and we’ll tell you exactly what to send first so we can make your visit worth your time.

How do I document endometriosis for work accommodations?

Documenting endometriosis for work accommodations starts with creating a clear paper trail that connects your diagnosis (or suspected diagnosis) to specific functional limits at work. Keep a simple symptom log for at least 4–8 weeks: date, symptom (pelvic pain, fatigue, bowel/bladder pain, heavy bleeding), severity, duration, triggers, and exactly what work tasks were affected (missed shifts, reduced standing tolerance, inability to sit, concentration issues, frequent bathroom breaks). Save objective documentation too—operative and pathology reports if you’ve had surgery, imaging reports when available, ER/urgent care notes, medication or treatment history, and any workplace attendance or performance impacts that occurred during flares.


For an accommodation request, what usually helps most is a concise clinician letter that focuses on work restrictions rather than extensive medical detail—e.g., need for flexible scheduling during flares, ability to work from home at times, breaks for pain management/restroom access, limits on prolonged standing/sitting, or intermittent leave when symptoms are unpredictable. If you’re pursuing disability benefits, the same principle applies: decision-makers look for consistent records over time showing that symptoms significantly interfere with your ability to perform job duties, since endometriosis isn’t automatically classified as a disability.


Our team can help you organize the records that best support your case and, when appropriate, provide medical documentation that reflects the reality of your symptoms and functional limitations. If you’d like, reach out to schedule a consultation so we can review what you already have and identify what additional documentation would be most useful for workplace accommodations.

How do I explain endometriosis to my employer?

It often helps to keep your explanation simple and work-focused: endometriosis is a chronic inflammatory condition where tissue similar to the uterine lining grows outside the uterus and can cause significant pelvic pain, fatigue, and GI or bladder symptoms. Symptoms can flare unpredictably and aren’t always limited to your period, which is why you may need flexibility at certain times. You don’t need to share intimate details—just the functional impact (for example: pain, fatigue, and medical appointments can affect attendance, sitting/standing tolerance, or concentration).


If you’re requesting support, be specific about what would help you do your job well, such as intermittent time off for flares, the ability to work from home when symptoms spike, scheduled breaks, or flexibility around medical visits and potential procedures. Many patients find it useful to frame this as a long-term health condition with variable days rather than a one-time illness, and to document patterns of symptoms and missed work so your needs are clear.


If you’d like, our team can help you describe your condition and anticipated care in a medically accurate way that supports workplace accommodations, especially if symptoms are affecting your ability to function consistently. You can also explore our educational resources on endometriosis and work impacts, and reach out to schedule a consultation if you’re looking for a clearer plan for diagnosis and treatment.
