Endometriosis excision is a surgical procedure that involves the careful and complete removal of endometriotic tissue, which is tissue similar to the lining of the womb (endometrium) that grows outside the uterus. This abnormal tissue can appear on organs such as the ovaries, fallopian tubes, pelvic walls, bowel, and bladder, causing pain, inflammation, and scarring.
Unlike ablation, which only burns the surface of the lesions, excision removes the tissue in its entirety, including its deeper roots. This makes excision a more thorough and effective treatment option for managing endometriosis. By precisely removing the abnormal growths, excision surgery aims to alleviate pain, restore pelvic anatomy, and address the underlying cause of symptoms.
Performed using minimally invasive techniques, excision is widely regarded as the first-line surgical treatment for endometriosis due to its ability to provide long-term relief and reduce the risk of recurrence.
Endometriosis can significantly impact a woman’s quality of life, causing severe pelvic pain, menstrual irregularities, and fertility challenges. At Dr Ma Li’s Clinic, we specialise in endometriosis excision surgery, the most effective approach for managing this condition. By targeting the root cause of symptoms, we aim to deliver long-term relief and help you reclaim your health and well-being.


The surgeon also addresses any scar tissue or adhesions that may have formed as a result of endometriosis. Adhesions, which are bands of scar tissue that can bind organs together, may contribute to pain and impaired function of pelvic organs. During excision, these adhesions are carefully dissected to restore normal anatomy.
Throughout the procedure, the surgeon ensures that all visible endometriotic tissue is removed while preserving the health and function of nearby organs such as the ovaries, fallopian tubes, bladder, and bowel. The excised tissue may be sent for histological examination to confirm the diagnosis of endometriosis and rule out any other conditions.
Once the excision is complete, the instruments are removed, and the incisions are closed with dissolvable sutures. The minimally invasive approach results in smaller scars, reduced postoperative pain, and faster recovery compared to open surgery.
The procedure is performed using a minimally invasive surgical technique known as laparoscopy. This procedure allows for precise removal of endometriotic tissue while minimising trauma to surrounding healthy structures. The process begins with the patient being placed under general anaesthesia to ensure comfort and immobility during the surgery. Small incisions, usually less than a centimetre, are made in the abdomen to serve as access points for the surgical instruments. A laparoscope, a thin tube with a light and high-definition camera, is inserted through one of the incisions to provide a magnified, detailed view of the pelvic cavity.
Using this enhanced visualisation, the surgeon carefully identifies endometriotic lesions, adhesions, and abnormal tissue. Specialised surgical tools are then used to meticulously excise (cut out) the endometriotic growths, removing them in their entirety, including any deeply infiltrating areas. Unlike ablation, which only destroys the surface of the lesions using heat or lasers, excision removes the full depth of the tissue. This distinction is critical, as incomplete treatment can allow the disease to persist and symptoms to recur.
Widely regarded as the most effective surgical approach, excision removes abnormal endometriosis tissue completely, offering lasting relief and significant improvements in quality of life.
The benefits include:
These benefits make excision the preferred choice for patients seeking lasting relief and effective management of endometriosis symptoms.
The procedure is often used to address a range of circumstances and conditions where endometriosis significantly impacts health and quality of life. Our personalised approach ensures that excision is used when it offers the most effective solution for your symptoms and concerns.

Personalised care is provided at every stage of the journey. From the first consultation to recovery and beyond, the focus is on addressing your unique symptoms, concerns, and goals.
Your treatment journey typically includes:

Long-term results
Endometriosis excision is typically performed as a single, comprehensive surgical procedure. The goal is to meticulously remove all visible endometriotic tissue and adhesions during one session, ensuring thorough treatment and minimising the need for repeat surgeries. However, the complexity of endometriosis can vary from patient to patient. In cases where the disease is extensive, deeply infiltrating, or involves multiple organs such as the bowel, bladder, or diaphragm, additional sessions may occasionally be required to address all affected areas safely.
At Dr Ma Li’s Clinic, we take a personalised approach, using advanced imaging and diagnostic techniques before surgery to carefully map the extent of the disease. This preparation allows us to plan the excision procedure effectively and maximise results in a single session. During your consultation, Dr Ma Li will discuss the anticipated treatment plan based on the severity and location of your endometriosis, and ensure that you are well-informed about your treatment journey.
If you are experiencing persistent pelvic pain, fertility challenges, or other symptoms of endometriosis, schedule a consultation with Dr Ma Li today to explore how excision surgery can help you achieve lasting relief and improved quality of life.
