From: Imaging the operated colon using water-enema multidetector CT, with emphasis on surgical anastomoses
Two examples of water-enema multidetector CT (WE-MDCT) via the colostomy (surgical schemes shown in insets). a–c performed before elective bowel recanalisation in a 79-year-old female with previous Hartmann’s resection of the sigmoid and descending colon for complicated diverticulitis. Optimal retrograde distension of the residual large bowel up to the ileocecal valve (thin arrow in b) is achieved using a Foley catheter (thick arrow in a) positioned in the left-sided stoma. Note the closed rectal stump (+ in c). d–e) performed via the permanent colostomy in an 85-year-old male following abdomino-perineal resection for perforated rectal cancer (note absent rectum in e). Segmental poor distension of the pre-stomal tract (arrowheads in d, e) surrounded by stomal herniation of small bowel loops. Optimally distended descending, transverse and right colon (in f) without abnormalities
