What Shall We Do Now? Report of Unexpected CT Finding and Its Management

Abstract

A 41 years old patient underwent total colectomy and ileal pouch-anal anastomosis with derivative ileostomy for a familiar adenomatous polyposis coli in June 2008. Pathologic examination of the specimen showed a pT1 N1 adenocarcinoma of the rectum. The patient underwent chemo-radiation and subsequent adjuvant chemotherapy. A stenosis of the pouch-anal anastomosis developed. The patient underwent several endoscopic dilations. The ileostomy was taken down in March 2016. A recurrence of the stenosis and a peri-anastomotic collection were observed. An endoscopic drainage of the collection was performed on October 3rd, 2016.
