To determine the safety and efficacy of laparoscopic management of ovarian dermoid cysts based upon our ten years' experience.


Charts of 81 patients who underwent laparoscopic removal of dermoid cysts since March 1988 at Stanford University Medical Center or the Center for Special Pelvic Surgery in Atlanta were reviewed retrospectively.


Ninety-three dermoid cysts with a mean diameter of 4.5 cm were removed in 81 patients. Operative techniques used were cystectomy for 70 cysts, salpingooophorectomy for 14, and 9 salpingo-oophorectomy with hysterectomy. Fifty-three cysts were treated via enucleation followed by cystectomy or salpingo-oophorectomy and removal through a trocar sleeve. Twenty-two were treated via enucleation and removal within an impermeable sack. Nine were treated via enucleation and removal by posterior colpotomy. Nine were removed via colpotomy following hysterectomy. We had a total of 39 spillages. Spillage rates varied with removal method: 32 (62%) for trocar removal without an endobag, 3 (13.6%) for removal within an endobag, and 4 (40%) with colpotomy removal. No spillage occurred for the nine patients who had a colpotomy done for hysterectomy. Mean hospital stay after surgery was 0.98 days, and there were no intraoperative complications. In one case, there was a postoperative complication of an incisional infection in the umbilicus.


Including this and 13 other studies, review of the literature reveals a 0.2% incidence of chemical peritonitis following laparoscopic removal of dermoid cysts. Thus, we conclude that laparoscopic management of dermoid cysts is a safe and beneficial method in selected patients when performed by an experienced laparoscopic surgeon.
