title: Spiral colon bypass in a geriatric Vietnamese potbellied pig.
abstract: An 8-year-old potbellied pig was evaluated for anorexia, decreased fecal production, signs of depression, inappetence, and abdominal distension. During hospitalization, a tooth root impaction and abscess were diagnosed, and abdominal radiography revealed severely distended, gas-filled large and small intestines. Exploratory laparotomy revealed a stricture of the proximal centripetal loop of the spiral colon and megacolon of the proximal portion of the spiral colon and cecum. A side-to-side spiral colon anastomosis was performed to create a partial bypass of the spiral colon. The success of this procedure suggests that spiral colon bypass is a treatment option for spiral colon stricture formation in potbellied pigs. Spiral colon stricture formation should be considered as a differential diagnosis in geriatric potbellied pigs that are anorectic, have abdominal distension, and have decreased fecal production.
