Right nephrectomy. Cluster of abnormal loops of small bowel within the nephrectomy bed which are fluid-filled, have thickened walls with slightly diminished enhancement, and are associated with mesenteric edema. The afferent and efferent loops of this cluster converge centrally at a single point, consistent with passing through an internal hernia defect or tight adhesive band. Proximally, the small bowel is mildly dilated with gradual transition of enteric contrast into fluid-filled loops of bowel. Distally, the small bowel is decompressed.
