Small bowel volvulus following ileal pouch-anal anastomosis: CT demonstration.
We report a case of acquired small bowel volvulus as a cause of late obstruction after ileal J-pouch anal anastomosis. Computed tomography (CT) demonstrated signs of strangulated, adhesive obstruction with radial disposition of the loops around the mesenteric root and abnormal position of the superior mesenteric artery and vein on the right side of the aorta. These features were due to the surgical manipulation and tension of the mesentery and its vessels during ileoanal anastomosis.
