Endometriosis - Conservative Surgery

(Page 2)

• Carbon dioxide gas is injected into the abdomen, distending it and pushing the bowel away so that the doctor has a wider view.
• The procedure requires making small incisions at the navel and above the pubic bone.
• The laparoscope (a hollow tube equipped with camera lenses and a fiber optic light source) is inserted through the incision at the navel (the umbilical incision).
• A probe is then inserted through the second incision allowing the doctor to directly view the outside surface of the uterus, fallopian tubes, and ovaries.
• One or two additional small incisions can be made on either side of the lower abdomen through these incisions. Surgical instruments or other devices are passed through these accessory incisions to destroy or remove abnormal tissue. Implants can be removed by excision (surgical removal) using a laser or scissors or by destroying the area with lasers or with electricity (or electrocautery).

In one study, laparoscopy achieved pain relief in over 62% of women. A more recent study conducted 3-12 months post-surgery in women with severe (stage III/IV) endometriosis suggested 88% of patients were satisfied with the procedure.

In addition, pregnancy rates can range from 20% to over 50% after laparoscopy. (The procedure does not reduce the chances for pregnancy in women who must still undergo assisted reproductive techniques to conceive.) Still, recurrence rates for laparoscopy are no better than those with laparotomy -- the more invasive procedure.

Laparotomy uses a wide abdominal incision and conventional surgical instruments. It is more invasive and requires a longer recovery time. In some severe cases, the doctor may need a wider view of the pelvic area and will perform this procedure. Laparotomy is typically used for infiltrating endometriosis, although the less invasive laparoscopy is showing increasing effectiveness, even for deep implants.

Complications after Surgery. Many patients experience temporary but severe discomfort in the shoulders after laparoscopy due to residual carbon dioxide gas that puts pressure on the diaphragm. The incisions, even with laparoscopy, may cause pain afterward, which can usually be treated effectively with mild pain relievers. There are small risks for bleeding, infection, and reaction to anesthesia. Surgery in the pelvic area may also cause scarring, which may cause pain and interfere with fertility.
