Retractile mesenteritis with ileal loop trapped by adhesion. About 10 days after transplantation, an upper obstruction was apparent. A Radiologic study with oral contrast agent indicated preferential opacification of the loop, without passage of contrast agent to the efferent loop or visualization of ileal loops. B CT examination highlights mesenteric thickening and the presence of some lymph nodes that are larger than normal. C Postoperative radiologic examination displays transit recovery with rapid opacification of the loop and passage of contrast agent into the small bowel.
