Deep Disease
What bowel endometriosis techniques are used, and what risks?
The short answer
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.
For bowel endometriosis, we tailor surgical options to how deep the disease goes and how much of the bowel wall is involved. Depending on the nodule’s size and location, we may use superficial shaving, a full-thickness discoid excision, or a segmental bowel resection to remove disease while protecting bowel function.
Each approach has different risks, which we review with you during pre-op planning so you understand why we recommend a specific technique. Potential complications can include a bowel leak, fistula, temporary ostomy, nerve-related changes, and altered bowel habits during recovery. Our goal is to balance thorough disease removal with safety and long-term function. During a consultation with our team, we’ll walk you through what to expect before and after surgery.

Questions people ask next
All deep disease questionsShaving vs disc vs bowel resection for endometriosis: what’s the difference?
Shaving removes disease from the bowel surface, disc excision removes a full-thickness piece of bowel wall, and segmental resection removes a bowel segment and reconnects the ends. The choice depends on lesion depth, size and location, bowel narrowing, symptoms and your goals.
How is bowel endometriosis treated without a colostomy?
In many cases, bowel endometriosis can be treated surgically without a colostomy by removing disease from the bowel surface or removing deeper disease and repairing or reconnecting the bowel. A temporary stoma may be recommended in select higher-risk situations.
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.
What are the main risks of endometriosis excision, and how are they minimized?
The main risks of endometriosis excision are bleeding, infection, scar tissue (adhesions), and injury to the bowel, bladder or ureters. We minimize these risks with careful surgical planning, meticulous technique to protect organs and nerves, and the right expertise and tools.
