Abstract
A 51-year-old man seen for abdominal pain and fullness was found in abdominal computed tomography (CT) to have portal venous gas and intestinal pneumatosis. We conducted emergency laparotomy due to panperitonitis. Operative findings showed perforation of a gangrenous appendicitis and dilation of the small intestine, but us bowel necrosis. We conducted appendectomy and cecostomy. This is the third case of portal venous gas caused by acute appendicitis reported in the Japanese literature.
