Laparoscopic resection of intestinal endometriosis: A 5-year experience

STUDY OBJECTIVE: To describe the clinical manifestations, surgical techniques, and complications observed in patients undergoing laparoscopic resection of intestinal deeply infiltrating endometriosis (DIE). DESIGN: Prospective nonrandomized (Canadian Task Force Classification II-3). SETTING: University hospital and private practice. PATIENTS: We evaluated 125 patients with intestinal DIE treated from February 2000 through September 2005. INTERVENTIONS: Laparoscopic radical excision of DIE followed by resection of the rectosigmoid colon. MEASUREMENTS AND MAIN RESULTS: The clinical examination of our patients demonstrated that 66.4% of patients had tenderness, whereas 80.8% had nodules on the pouch of Douglas. In 95.2% we observed pain caused by cervical mobilization, and all the patients had pain during the pouch of Douglas mobilization. Regarding bowel infiltration, preoperative investigation with rectal endoscopic ultrasonography was positive in all cases. Endoscopic rectal ultrasonography demonstrated the depth of intestinal infiltration. Superficial lesions were observed in 9.6% of patients and muscularis involvement in 71.2%. The segmental resection was performed in most of the patients (92%) and the linear resection in 6.4% of them. Median surgical time was 110 minutes, and the median hospital stay was 7 days after the surgery; the patients continued fasting for 3 to 7 days. The return to normal activity was achieved in a median 15 days after the surgery. The surgical procedure and the postoperative follow-up demonstrated no complications in 90.4% of the patients. Minor complications were observed in 4% of the cases. Major complications occurred in 5.6% of the patients, including 2 cases of intestinal fistulas (1.6%) and 3 cases of long-lasting urinary retention (2.4%). CONCLUSION: Clinical symptoms of patients with intestinal endometriosis are not specific. Operative laparoscopy is a safe and effective method to treat intestinal endometriosis. To avoid major complications, special attention must be paid to the intestinal anastomosis and to the nerve preservation. (C) 2006 AAGL. All rights reserved.
