Sigmoid colon endometriotic mass. A rare cause of complete large bowel obstruction.
Large bowel obstruction is a rare complication of gastrointestinal endometriosis. A 32-year-old female patient presented to the emergency department with complaints of diffuse abdominal pain and constipation for 10 days with progressive abdominal distention and vomiting. Plain abdominal x-ray showed grossly dilated large bowel up to the sigmoid colon with no gas in the rectum. Abdominal computed tomography revealed hugely dilated large bowel up to the sigmoid colon, with sigmoid soft tissue mass. Flexible sigmoidoscopy showed a non-ulcerating sigmoid mass, with complete obstruction of the sigmoid colon, which impeded the further advancement of the scope. She underwent exploratory laparotomy with provisional diagnosis of complete large bowel obstruction due to sigmoid tumor. Sigmiodectomy with end colostomy was performed. Histopathology revealed endometrial glands with stroma in muscularis properia of the sigmoid colon mass. Endometriosis should be considered in women of reproductive age presenting with symptoms of large bowel obstruction.
