Excision vs. Ablation: What Your Surgeon Won't Tell You Before You Consent
Before you schedule any surgery for endometriosis, you need to understand the difference between these two approaches. It is the difference between relief and recurrence.

You've finally been referred for surgery. Your pain is being taken seriously, at least enough for a laparoscopy to be on the table. This is progress, but it is not the end of the advocacy work. What happens in that operating room depends entirely on who is holding the instruments and what approach they use.
Most women are not told before their surgery whether their surgeon plans to perform ablation or excision. Many don't know there's a difference. This post changes that.
The Two Approaches — Side by Side
There are two primary surgical methods for treating endometriosis lesions. They are not equivalent:
✦ Ablation (Burning / Laser)
Ablation destroys the surface of endometriosis lesions using heat, laser, or electrical current.
What it does: Eliminates the visible surface of a lesion.
What it leaves: The root structure, nerve supply, and blood supply of the lesion — intact.
Result:Temporary symptom relief, with recurrence rates cited up to 80% within 5 years in some studies.
Commonly performed by: General OBGYNs without endo specialization. Faster procedure, less technical skill required.
✦ Deep Excision — The Gold Standard
Excision surgically removes endometriosis lesions entirely, including the root, nerve supply, and blood supply included.
What it does: Removes the entire lesion, not just its surface.
What it leaves: Nothing of the lesion. The healthy tissue around it is preserved.
Result: Significantly lower recurrence rates. Longer-lasting pain relief. Considered the gold standard of care.
Performed by: Trained excision specialists, fewer in number, requiring additional expertise.
The distinction matters because endo lesions extend beneath the surface. Ablation destroys what is visible on the outside of the lesion while leaving the root intact. That root continues to produce estrogen, continues to create inflammation, and in many cases continues to grow.
Why Ablation Has Such High Recurrence
Ablation was widely used for decades in endo surgery, and many general OBGYNs still default to it often without clearly explaining what the alternative is. The recurrence figures tell the story:
Studies have found ablation recurrence rates as high as 80% within 5 years
Many women report symptom return within 12–18 months post-ablation
Repeated ablation can create more adhesions during the healing process, potentially worsening the disease picture
Ablation is particularly inadequate for deep-infiltrating endometriosis, where lesions penetrate deeper tissues
If you previously had surgery and your symptoms returned or intensified, ablation may be the reason. This is not your body failing. It is a predictable outcome of a surgical approach that does not address the root of the disease.
The Research Behind Deep Excision
The superiority of excision over ablation is supported by multiple studies and endorsed by leading surgical organizations:
A systematic review published in the Journal of Minimally Invasive Gynecology found excision to be superior to ablation for pain reduction and long-term outcomes
The World Endometriosis Society and AAGL (American Association of Gynecologic Laparoscopists) recognize deep excision as the preferred surgical treatment
The 2021 International Terminology for Endometriosis (AAGL/ESGE/ESHRE/WES) emphasizes excision as the approach required to address the root biology of endo lesions
✦ A Note on Surgeon Availability
Skilled excision surgeons are not uniformly distributed. In some regions you may need to travel. This is not a reason to accept ablation as 'good enough.' Many women travel out of state or internationally for excision surgery because the difference in outcomes justifies it.
The directories at the end of this post will help you find a trained excision specialist wherever you are.
Before You Consent: The Questions to Ask
These questions should be asked in your surgical consultation — before you agree to any procedure:
'Do you perform deep excision, or ablation?' If they don't differentiate or can't explain the difference, leave.
'How many excision surgeries have you performed in the last year specifically?'
'Do you operate on bowel, bladder, and ureteral endo? Do you work with a colorectal surgeon or urologist when needed?'
'How do you handle lesions that are close to major structures like the ureter, bowel wall, or diaphragm?'
'What is your estimated recurrence rate in patients you have treated?'
'If you find endo during this procedure that you can't safely excise, what is your plan?'
A surgeon who is confident in excision will answer these questions directly. A surgeon who is uncomfortable with them is telling you something.
Red Flags in a Surgical Consultation
Surgeon mentions ablation without explaining the alternative or is unfamiliar with the distinction
Surgeon dismisses your bowel, bladder, or leg symptoms as unrelated to endo
Surgeon suggests 'just burning whatever we see' without discussing excision
Surgeon discourages a second opinion from a specialist
Surgeon recommends years of hormonal suppression before surgery 'to see if it helps' when you are already in significant pain
After Surgery: Pelvic Floor PT
No discussion of endo surgery is complete without addressing pelvic floor physical therapy. For most women with endometriosis, the pelvic floor has been in a state of chronic protective guarding bracing against anticipated pain for months or years. Excision removes the source of inflammation. Pelvic floor PT addresses the neuromuscular legacy.
A pelvic floor PT can address muscular hypertonicity, scar tissue mobility post-surgery, sexual pain, and bladder and bowel dysfunction. This is not optional aftercare. It is part of a complete surgical recovery for endo.

Frequently Asked Questions
Q: Is ablation ever appropriate for endometriosis?
A: In limited situations — such as superficial peritoneal endo in a patient who is not a surgical candidate for more extensive excision, ablation may be offered. However, for the majority of women with endo, and particularly those with deep infiltrating disease, excision is significantly superior in outcomes. If ablation is being recommended as the primary approach, ask why excision is not being offered.
Q: I had ablation and my symptoms are back. Can I still have excision?
A: Yes. Recurrence after ablation does not preclude excision surgery. A skilled excision surgeon can operate on previously ablated tissue. The scar tissue from prior ablation may make the procedure more technically complex, which is one reason to seek an experienced specialist.
Q: My doctor says excision is riskier. Is this true?
A: Excision does carry surgical complexity that ablation does not, particularly when endo involves the bowel, bladder, or major vessels. However, 'riskier' surgery performed by a highly trained specialist is often safer and more effective than 'simpler' surgery performed by someone without appropriate training. The relevant question is not which surgery is riskier in the abstract, but whether the surgeon performing it has the skill required.
Q: How do I find out what approach my surgeon uses before booking?
A: Call the surgeon's office and ask directly: 'Does Dr. [name] perform deep excision surgery for endometriosis, or ablation?' You can also check the iCareBetter and Nancy's Nook directories, which include patient reviews that often specify surgical approach.
