Single-incision Laparoscopic Surgery for Bowel Obstruction Secondary to Intestinal Endometriosis—A Report of Two Cases—

Abstract

Case 1 : A 32-year-old woman presented with intermittent abdominal pain and vomiting. Computed tomography (CT) and colonoscopy (CS) revealed bowel obstruction secondary to ileocecal stenosis. The patient's preoperative serum cancer antigen 125 (CA125) level was elevated, leading to a high index of clinical suspicion for intestinal endometriosis. After decompression using a long tube, we performed single-incision laparoscopic partial ileal resection. The patient's postoperative course was uneventful, and she was discharged on postoperative day 8.

Case 2 : A 37-year-old woman with a history of endometriosis desired to get pregnant and discontinued hormone therapy, which led to repeated episodes of left lower abdominal pain during menstruation. The patient's preoperative serum CA125 level was elevated, and CT and CS revealed stenosis and mucosal edema of the sigmoid colon. We performed single-incision laparoscopic sigmoidectomy, and she was diagnosed with intestinal endometriosis. The patient's postoperative course was uneventful, and she was discharged on postoperative day 9. Histopathological examination of the resected specimen showed intestinal endometriosis. The patient underwent successful minimally invasive single-incision laparoscopic surgery for bowel obstruction caused by intestinal endometriosis.
