A Case of Laparoscopic Sigmoidectomy for Colonic Fistula due to Mesh Plug for Inguinal Hernia Surgery

Abstract

A 62-year-old man visited our hospital complaining of a positive fecal occult blood test. The patient had a history of hernia repair with a mesh plug at another hospital two years previously. Colonoscopy revealed a tumor that appeared as a plug in the lumen of the sigmoid colon, and computed tomography (CT) revealed a mass between the sigmoid colon and the abdominal wall. We planned a laparoscopic surgery for the diagnosis of a colonic fistula due to a mesh plug. Intraoperative findings showed that the plug had adhered to the sigmoid colon ; therefore, a laparoscopic sigmoidectomy was performed. We did not remove the onlay mesh or reinforce the posterior inguinal wall. The patient was discharged 12 days after the surgery with no complications and did not experience a hernia recurrence one year later. We experienced a case of laparoscopic sigmoidectomy for a colonic fistula caused by a mesh plug. Laparoscopic surgery seemed feasible in cases without infection, and posterior wall reinforcement seemed unnecessary.
