Abstract

BACKGROUND: Endometriomata are endometriotic deposits within the ovary. The surgical management of these blood filled cysts is controversial. The laparoscopic approach to the management of endometriomata is favoured for as it offers the advantage of a shorter hospital stay, faster patient recovery and decreased hospital costs. Currently the commonest procedures for the treatment of ovarian endometriomata are either excision of the cyst capsule or drainage and electrocoagulation of the cyst wall. OBJECTIVES: The objective of this review was to determine the most effective technique of treating an ovarian endometrioma; either excision of the cyst capsule or drainage and electrocoagulation of the cyst wall, with regard to relief of pain, recurrence of the endometrioma, recurrence of symptoms and the subsequent spontaneous pregnancy rate. SEARCH STRATEGY: The reviewers searched the Cochrane Menstrual Disorders and Subfertility Group specialised register of trials (searched 15 Nov 2004), the Cochrane Register of Controlled Trials (The Cochrane Library, Issue 4, 2004), MEDLINE (1966-Nov 2004), EMBASE (1980- Nov 2004) and reference lists of articles, the handsearching of relevant journals and conference proceedings and by contacting leaders in the field of endoscopic surgery throughout the world. SELECTION CRITERIA: Randomised controlled trials of excision of the cyst capsule versus drainage and electrocoagulation of the cyst in the management of ovarian endometriomata. DATA COLLECTION AND ANALYSIS: Reviewers assessed eligibility and trial quality. MAIN RESULTS: No randomised studies of the management of endometriomata by laparotomy were found. Two randomised studies of the laparoscopic management of ovarian endometriomata of greater than 3cm in size were included. Laparoscopic excision of the cyst wall of the endometrioma was associated with a reduced rate of recurrence of the endometrioma (OR 0.41 CI 0.18-0.93), reduced requirement for further surgery (OR 0.21 CI 0.05-0.79), reduced recurrence rate of the symptoms of dysmenorrhoea (OR 0.15 CI 0.06-0.38), dyspareunia OR 0.08 CI 0.01-0.51) and non-menstrual pelvic pain (OR 0.10 CI 0.02-0.56). It was also associated with a subsequent increased rate of spontaneous pregnancy women who had documented prior sub-fertility (OR 5.21 CI 2.04-13.29). AUTHORS' CONCLUSIONS: There is some evidence that excisional surgery for endometriomata provides for a more favourable outcome than drainage and ablation, with regard to the recurrence of the endometrioma, recurrence of symptoms and subsequent spontaneous pregnancy in women who were previously subfertile. Consequently this approach should be the favoured surgical approach. However we found no data as to the effect of either approach in women who subsequently undergo assisted reproductive techniques.
