A stenosis of the pouch-anal anastomosis developed. The patient underwent several endoscopic dilations. A recurrence of the stenosis was observed. The patient underwent to several endoscopic procedure. After the last colonoscopy the patient showed a fever with abdominal pain. A CT scan showed little peri-anastomotic collections and massive hepatic portal venous gas.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion:<\/jats:title>\n                    <jats:p>The management of HPVG varied from surgical intervention to non-operative procedure.
