Abdominal wall endometrioma after cesarean section: a preventable complication.

The occurrence of abdominal wall scar endometrioma after cesarean section has been reported previously in the literature. However, steps to prevent this complication have not been delineated. A study was undertaken of six patients seen at our general surgical clinic, each of whom had presented with a painful mass at a previous cesarean section site. Ages ranged from 20 to 34 years. The duration of their symptoms ranged from 6 to 84 months. All patients underwent surgical exploration and excision of the mass, which was revealed by histology to be endometrioma. It is strongly recommended that, at the conclusion of the procedure of cesarean section, the abdominal wall wound be cleaned thoroughly and irrigated vigorously with high-jet saline solution before closure.
