Use of an incontinent end‐on colostomy in a dog with annular rectal adenocarcinoma

Abstract

An 11-year-old, mixed-breed dog with dyschezia, tenesmus and haematochezia was presented. A rectal stricture caused by an adenocarcinoma was diagnosed. Following the failure of a rectal 'pull-through' procedure, which dehisced seven days later, an incontinent end-on colostomy was performed, allowing amputation of the colorectum with the anus and perineal skin. A two-piece device consisting of a flange and a drainable pouch was used for postoperative faecal evacuation and collection. Mild peristomal dermatitis was the only complication. Patient management was easily carried out by the owner at home, and the dog survived for four months with a satisfactory quality of life. Incontinent end-on colostomy may prove to be a useful treatment for canine annular colorectal tumours.
