虫垂切除術後の高排出性結腸皮膚瘻に対する腹腔鏡下修正術：症例報告

Colo-cutaneous fistulae are rare complications following appendectomy, especially when high-output, and can cause significant morbidity. We report a 66-year-old male who presented nine days post-open appendectomy with fecal discharge from the incision. Imaging showed cecal adherence to the anterior abdominal wall, consistent with a colo-cutaneous fistula. Conservative management failed, with persistent high-output drainage of 600-1000 mL/day. The patient underwent laparoscopic revision, including adhesiolysis, mobilization of the terminal ileum and ascending colon, and resection with extracorporeal ileocolic anastomosis. Postoperative wound healing was managed with secondary intention and negative pressure therapy. The patient recovered well and was discharged in stable condition. This case demonstrates the effectiveness of laparoscopic intervention in high-output colo-cutaneous fistulae and highlights the need for timely surgical management when conservative measures fail.
