Can bowel endometriosis surgery cause an anastomotic leak?
The short answer
Yes, bowel endometriosis surgery that involves cutting and reconnecting the bowel can cause a leak at the connection. Leaks are uncommon in experienced hands, and the risk varies with the depth of disease and the type of bowel procedure.
Yes, any time endometriosis surgery involves cutting and reconnecting the bowel (for example, a segmental resection), a leak at that connection is a known potential complication. Not every bowel endometriosis procedure carries the same risk: techniques like superficial shaving of disease on the bowel wall generally differ from disc excision or full segmental resection. The risk profile changes with how deep the disease is and what has to be repaired.
The good news is that leaks are uncommon in experienced hands. Risk depends largely on planning and technique: accurate pre-op mapping, choosing the least invasive bowel approach that still fully treats the disease, and having the right multidisciplinary team available when the rectum/sigmoid colon are involved. In our practice, we emphasize meticulous robotic excision for precision and tissue handling, which is especially important in complex, scarred anatomy.
If you’re considering surgery for suspected bowel endometriosis, we encourage you to explore how different bowel procedures are selected and what your individualized surgical plan would involve (including who will be in the operating room and what safeguards are used). During a consultation, our team can review your symptoms and imaging, explain which bowel technique may be appropriate for your case, and walk you through complications like leaks in a clear, practical way.

Questions people ask next
All surgery questionsWhat bowel endometriosis techniques are used, and what risks?
Bowel endometriosis surgery may use superficial shaving, full-thickness discoid excision, or segmental bowel resection, depending on disease depth and extent. Potential complications can include bowel leak, fistula, temporary ostomy, nerve-related changes, and altered bowel habits during recovery.
Will endometriosis excision surgery need bowel resection or a stoma?
Most endometriosis excision surgeries do not require a bowel resection, and a stoma is uncommon. These possibilities come up mainly when endometriosis grows deep into the bowel wall or scar tissue has significantly distorted the anatomy.
Do I need a colorectal surgeon for bowel endometriosis surgery?
Sometimes, especially if imaging or an exam suggests deeper bowel involvement that may require opening, repairing or removing part of the bowel. A general surgeon or gynecologic oncologist credentialed in bowel surgery may also provide the needed expertise.
