A New Technique for Laparoscopic Anterior Resection for Rectal Endometriosis

BACKGROUND: Anterior rectal resection is sometimes necessary to treat deeply infiltrating rectovaginal endometriosis. We describe a completely laparoscopic approach as a new way of excising rectal endometriosis that can be used without opening any part of the rectum. This avoids opening the abdomen or any risk of fecal spillage. METHODS: The patient received preoperative oral bowel preparation. Ureteric stents (6 F) were inserted cystoscopically. The peritoneum in the ovarian fossae was opened lateral to any disease and the rectum reflected off the back of the cervix, leaving any endometriosis on the front of the rectum. The pelvic peritoneum was reflected medially, below the level of the ureters. The mesorectum was then dissected off a 6-cm length of rectum by using a Harmonic scalpel. A circular end-to-end anastomosis instrument was passed anally until the outline of the anvil was visible, inside the colon, above the diseased rectum. The anvil was detached and held by a soft grasper before the rectum was then divided above and below the disease using a laparoscopic stapling device. The tip of the anvil was pushed through the proximal end of the colon allowing reanastomosis of the rectal stump. CONCLUSION: The patient was discharged after 5 days without complications.
