Between October 1986 and March 1990, 220 patients underwent surgical treatment for ovarian cysts. 156 of these patients underwent an initial celioscopy and could potentially benefit from celiosciopic treatment. The group mean age was 33.3 years. The circumstances under which the cysts were discovered usually consisted of pelvic pain or diagnosis during a routine examination. Twenty-four patients underwent laparotomy immediately after coelioscopy either due to a suspect macroscopic diagnosis either due to technical difficulties. 84.6 percent of the patients in the group were able to undergo celioscopic treatment only, essentially consisting of intraperitoneal cystectomy. The main advantages were the reduction in adherent sequelae in these women of a sexually active age, but also some financial savings related to the reduced duration of hospitalization and of sick leave. The theoretical reservations consist of the risk of malignancy and macroscopic diagnosis following coelioscopic exploration must be very restricted, with laparotomy whenever there is any doubt. No malignant tumor was escaped detection in this group.
