[Granulomatous peritonitis after laparoscopic surgery of an ovarian dermoid cyst. Diagnosis, management, prevention, a case report].

We report a case of granulomatous peritonitis which occurred following laparoscopic exeresis of a dermoid cyst of the ovary performed together with medically induced abortion. The peritoneal cavity was contaminated when the cyst ruptured during the procedure emptying sebum and hairs in the peritoneum. Abondant washing with aspiration of all the visible particles was done with a 5 mm canula. The diagnosis of granulomatous peritonitis was suggested with the development of persistant fever, degradation of the patient's general health, moderate abdominal pain and a nodular image at echography located on the operated ovary. The nodule was found to be an inflammatory granuloma on a foreign body. Two second-look laparotomies, one transrectal and the other via the xypho-pubian route, were required 1 month after the initial operation for complete cure. The diagnosis was confirmed on the pathology report.
