Abstract

Intussusception of the small bowel through an ileostomy is very rare; when it causes necrosis of the bowel, immediate surgery is required. Computed tomography (CT) features of intussusception through an ileostomy have not been reported in the literature. Herein, we report the typical CT features of intussusception through an ileostomy, followed by a brief literature review.

  Fig. 1 A 49-year-old man with intussusception through an ileostomy. A. Image showing loop ileostomy with a proximal stoma (arrows) and a distal stoma (curved arrow). The small bowel (arrowheads), edematous with color change, protruding through the proximal stoma. B. An axial enhanced computed tomography (CT) image revealing loop ileostomy with a proximal stoma (arrow) and a distal stoma (curved arrow). The small bowel protruding through a proximal stoma is intussuscepted with mesentery slips. This intussusceptum consists of inner (asterisk) and middle (arrowheads) layers. The proximal stoma is the intussuscipiens (arrow). C. An axial enhanced CT image revealing the protruded intussusceptum with the target sign [the inner layer (asterisk) and the middle layer (arrowheads)]. D. An oblique sagittal reconstructed enhanced CT image depicting the intussusception through the proximal stoma (arrows): the protruded intussusceptum [the inner layer (asterisk) and the middle layer (arrowheads)] through the proximal stoma (arrows).
