Laparoscopic repair of an incarcerated inguinal hernia containing the sigmoid colon with a colonoscope.

Here, we report the first case of laparoscopic surgery to repair an incarcerated colonoscope in an inguinal hernia containing the sigmoid colon. After colonoscopy was performed on a 74-year-old man with positive fecal occult blood test results, the colonoscope could not be withdrawn. A bulge consistent with an incarcerated colonoscope was found on examination of the patient's left inguinal area. Computed tomography revealed and led to the diagnosis of an incarcerated colonoscope in the sigmoid colon within the inguinal hernia. After confirmation during emergency laparoscopic surgery, the incarcerated sigmoid colon was reduced, and the colonoscope was removed under radiographic and laparoscopic guidance. No ischemic changes or serosal injuries were observed, averting the need for resection. A transabdominal preperitoneal approach with a mesh was then used to repair the inguinal hernia laparoscopically. The patient's postoperative recovery was uneventful, and no recurrence was observed at the 1-year follow-up.
