[An unusual cause of intestinal occlusion: endometriosis of the sigmoid].

Colo-rectal endometriosis involving extensive intestinal wall may result in obstruction. This report is based on two patients having symptomatic intestinal endometriosis that required operative treatment. Diagnostic, pathologic and therapeutic findings were reviewed. Current treatment is the removal of the endometriomas, while removal of the reproductive organs should be made only after evaluation on the patient's menstrual status, age and future pregnancy desire.
