We report a very rare case of rectal arteriovenous fistula following sigmoidectomy and discuss this case in the context of the existing literature. In A pril 2011, the patient, a man in his 60s, underwent laparoscopic sigmoidectomy with lymph node dissection for sigmoid colon cancer. Beginning in F ebruary 2012, he experienced frequent diarrhea. Abdominal contrast‐enhanced CT revealed local thickening of the rectal wall and rectal arteriovenous fistula near the anastomosis site. Rectitis from the rectal arteriovenous fistula was diagnosed. No improvement was seen with conservative treatment. Therefore, surgical resection was performed laparoscopically and the site of the lesion was confirmed by intraoperative angiography. The arteriovenous fistula was identified and resected. Postoperatively, diarrhea symptoms resolved, and improvement in rectal wall thickening was seen on abdominal CT . No recurrence has been seen as of 1 year postoperatively.
