Abstract
A 76-year-old man was admitted to our hospital with left inguinal pain and swelling. Thirteen years previously, he had undergone left inguinal hernioplasty with a mesh plug at another hospital. Abdominal CT revealed abscess formation adjacent to the sigmoid colon, and the presence of a colocutaneous fistula. After a barium enema, he was diagnosed as having a colocutaneous fistula between the sigmoid colon and the left inguinal region due to penetrated diverticulitis. After conservative drainage therapy for regression of the inflammation, an operation was performed. The operative findings showed that the sigmoid colon had strongly adhered to the left lower abdominal wall and the mesh plug had penetrated into the sigmoid colon wall. The mesh plug was removed and a sigmoidectomy was carried out. The patient was discharged from the hospital on the 18th day after the operation. Colocutaneous fistulas are a relatively rare complication in patients with inguinal hernioplasty with a mesh plug.
