A 74-year-old man presented to our hospital complaining of a sensation of retained feces. Colonoscopy revealed a rectal cancer. After preoperative chemoradiotherapy, laparoscopic Miles' operation was performed. On postoperative day 6, the patient complained of abdominal pain around the stoma. Contrast-enhanced computed tomography scanning revealed a low-density area with an air-fluid level near the descending colon. Intraperitoneal abscess resulting from the perforation of the descending colon diverticulum was diagnosed, and percutaneous abscess drainage was performed. However, the fistula persisted. Indigo carmine was injected into the drainage catheter and the perforated diverticulm was identified. The fistula was closed using three short clips. After the clipping, there was no liquid discharge from the drainage catheter. The patient was discharged on postoperative day 56.
