Chemical peritonitis: a rare complication of an iatrogenic ovarian dermoid cyst rupture.

Laparoscopy is the standard method for the diagnosis and treatment of ovarian dermoid cysts, which represent 10% to 15% of all ovarian tumors. This procedure offers many advantages including less postoperative pain, lower risk of wound complication, early ambulation, and more rapid convalescence. The risk of adhesion formation also is reduced. However, in the case of an ovarian dermoid cyst, the laparoscopic approach could result in chemical peritonitis caused by the spilled contents of a ruptured dermoid cyst. We report a case of chemical peritonitis after rupture of an ovarian dermoid cyst during laparoscopy. Two operations were required, and medical treatment was not beneficial. We discuss a possible new medication for the treatment of this complication and compare this case with other recent reports.
