From: A closer look at the stoma: multimodal imaging of patients with ileostomies and colostomies
CT reconstruction technique and expected findings of ileostomies. a Focused oblique-sagittal (note lateral obliquity in inset) image of a normal end ileostomy with uniform mural thickness and enhancement of the stomal tract (arrow), mild protrusion at external orifice. b oblique-sagittal images of a loop ileostomy identify non-thickened, collapsed efferent and afferent limbs (arrows). Note fluid flowing at the external orifice indicating stomal patency. c, d A typical defunctioning loop ileostomy with two limbs (arrows) on sagittal (c) viewing and coronal (d) appearance. Note mild thickening and hyperenhancement of peristomal skin in c (compared to a and b) consistent with cutaneous inflammation at physical examination
