Endometriosis Surgery: Weeding the Garden
Endometriosis surgery can be life-changing - but it’s also complex, nuanced, and often misunderstood. For some people, surgery brings dramatic relief. For others, it’s one step in a longer journey of managing a chronic condition. Understanding what surgery can (and can’t) do, how it’s performed, and how surgeon experience matters can help you decide whether it’s the right option for you.
This article walks through how endometriosis surgery works, the difference between excision and ablation, fertility-sparing and non-fertility-sparing approaches, and what recovery and long-term outcomes realistically look like.
What Is Endometriosis Surgery?
Endometriosis surgery is performed to identify and treat endometriosis lesions — tissue similar to the uterine lining that grows outside the uterus and can cause pain, inflammation, and scarring.
(You can read more about what endometriosis is in our linked endometriosis article.)
Unlike many other gynecologic conditions, endometriosis often does not show up well on imaging. Ultrasound and MRI can sometimes detect advanced disease, but many lesions remain invisible until surgery. Because of this, surgery is often both:
• Diagnostic — confirming the presence of endometriosis by visual inspection and, in some cases, pathology
• Therapeutic — treating disease by removing or destroying lesions
Successful surgery can often significantly improve symptoms and quality of life for the right patient.
When Is Surgery Considered?
For a long time, medical teaching framed endometriosis surgery as a last resort, something to consider only after other treatments had failed. That thinking is shifting.
Endometriosis surgery should be considered alongside other treatment options, not only after a failure of medical therapy. Surgery is an important part of endometriosis care because it is also the only way to definitively diagnose the condition.
Surgery may be considered when:
• A patient wants a definitive diagnosis of endometriosis
• A patient prefers surgical treatment over medical therapy
• Pain persists despite medical management
• Symptoms interfere with daily life, work, or relationships
• Fertility is a concern
• There is suspected deep or organ-involving disease
• The diagnosis remains unclear despite ongoing symptoms
That said, not everyone with endometriosis needs surgery. Medical management is effective for many people, and many patients prefer to avoid surgery if possible. That is a valid approach as well. The goal is choosing the option that fits your symptoms, priorities, and life, ideally in partnership with a provider you trust.
Excision vs. Ablation: Understanding the Difference
A helpful way to think about excision versus ablation is to imagine weeds in a garden.
• Excision is like pulling the weeds out by the roots. The entire weed is removed, making it less likely to grow back.
• Ablation is more like using a flamethrower on the garden. It destroys what’s visible on the surface, but if the roots aren’t reached, the weed may return.
Both approaches have a role in endometriosis surgery.
Excision
Excision involves cutting out endometriosis lesions completely, including disease beneath the surface. Tissue can be sent to pathology, allowing for diagnostic confirmation.
Studies have shown that excision is associated with:
• Lower rates of endometriosis recurrence
• Longer-lasting pain relief compared with ablation
Excision is particularly important for deep infiltrating disease and for lesions involving ligaments, bowel, bladder, ureters, or other deeper structures.
Ablation
Ablation destroys endometriosis lesions using heat or energy rather than cutting them out. It may be appropriate for:
• Superficial disease
• Areas where complete destruction of the lesion is achievable
• Situations where excision could risk damage to structures important for fertility, such as the surface of the ovary or fallopian tube
A limitation of ablation is that it does not provide tissue for diagnosis and may not treat deeper disease.
Combination Surgery
In practice, many experienced surgeons use both excision and ablation during the same operation. The goal is not ideology — it’s safe, complete treatment of all visible disease using the best tool for each lesion.
Disease Severity and Surgical Complexity
Endometriosis is a disease of inflammation, and over time it can cause fibrosis and adhesions — in other words, organs can become stuck together and normal anatomy distorted.
Endometriosis is often described using stages (I–IV) to reflect disease extent. However, stage does not reliably predict pain severity. Someone with minimal-appearing disease may have severe symptoms, while advanced disease can sometimes be relatively quiet.
As disease becomes more extensive, surgery becomes more complex and requires higher levels of surgical expertise.
Who Performs Endometriosis Surgery?
Historically, most endometriosis surgery was performed by general OB-GYNs. Today, many surgeons have additional fellowship training, often in minimally invasive gynecologic surgery or endometriosis-focused programs.
That said:
• Some highly experienced general OB-GYNs perform excellent endometriosis surgery
• Reproductive endocrinologists and gynecologic oncologists may be involved in certain cases
• Access and training vary by location
Endometriosis surgery is not something you want performed by someone who does it infrequently. Finding a surgeon who regularly treats endometriosis and is comfortable with the procedure matters.
The right doctor will not try to manage disease they don’t feel comfortable treating - they will refer you to the right set of hands if needed.
Fertility-Sparing vs. Non-Fertility-Sparing Surgery
When future pregnancy is a goal, surgery focuses on removing disease while preserving reproductive organs.
Excision of endometriosis has been shown in studies to:
• Improve spontaneous pregnancy rates in some patients
• Improve implantation and live birth rates, even when fertility treatment such as IVF is still needed
This is thought to be due to reduced inflammation and improved pelvic anatomy. Some patients still require fertility treatment, but surgery can meaningfully improve the odds for certain individuals.
If fertility is not a goal, surgery may focus on excising endometriosis along with removal of other pelvic organs, such as the uterus, fallopian tubes, and ovaries. This can help ensure more complete disease removal and eliminate potential sources of new endometriosis. It may also treat other conditions that commonly coexist with endometriosis, such as adenomyosis, fibroids, or ovarian cysts.
Recurrence Risk
Recurrence rates after endometriosis surgery vary widely depending on how recurrence is defined, how extensive the initial disease was, and how completely it was treated.
• After excision alone, recurrence rates range from about 20–50% within five years
• When the uterus is also removed, recurrence rates drop to approximately 10–15%
• When the uterus and both ovaries are removed, recurrence rates fall further, to around 5%
Removal of the ovaries significantly lowers recurrence risk, but does not completely eliminate endometriosis.
If the ovaries are removed, hormone replacement therapy is often needed. In patients with a history of endometriosis, this frequently includes progesterone or combined therapies to help prevent recurrence.
Is Surgery a Cure?
Endometriosis is considered a chronic condition. However, in some cases, disease is completely removed from the body and does not recur.
That said, there is always a chance of recurrence. Surgery can dramatically reduce symptoms and improve quality of life, but some patients may need additional treatment or surgery in the future. This reflects the nature of the disease, not a failure of care.
How Is Endometriosis Surgery Performed?
The vast majority of endometriosis surgery is performed using minimally invasive techniques, including laparoscopy or robotic surgery. These approaches allow surgeons to visualize the pelvis in detail and treat disease through small incisions.
In some cases, open surgery may be used due to surgeon experience, patient anatomy, or complicating factors. The surgical approach should be discussed ahead of time so expectations are clear.
Recovery and What to Expect
Recovery depends on the extent of surgery. Common experiences after minimally invasive surgery include:
• Abdominal soreness and bloating
• Fatigue
• Shoulder pain caused by gas used during laparoscopy
• Constipation or changes in bowel habits
Periods may be irregular, heavier, or more painful for the first one to three cycles before improving. Some people notice emotional changes or frustration during recovery, especially if symptom improvement is gradual rather than immediate.
Reducing Recurrence After Surgery
Medical management after surgery can help reduce recurrence risk and prolong symptom relief. Options may include:
• Continuous hormonal suppression
• Progestin therapy
• Hormone blockers in select cases
• IUD placement (if you kept your uterus)
An IUD can often be placed during surgery, allowing for pain-free insertion and immediate benefit
Risks and Limitations
Risks include bleeding, infection, injury to surrounding organs, adhesion formation, and incomplete excision. Complex disease increases surgical risk, which is why surgeon experience matters.
The Bottom Line
Endometriosis surgery can be powerful, but it is not simple. Excision and ablation are tools — not opposing philosophies. Fertility goals, disease severity, surgeon experience, and long-term management all matter.
The best outcomes come from thoughtful planning and a surgeon who treats endometriosis regularly. A good decision is one that fits your symptoms, your goals, and your life.
