Case Description—A 5-year-old castrated male Vietnamese pot-bellied pig (Sus scrofa) was evaluated because of anorexia, vomiting, diarrhea, and weight loss.

Clinical Findings—Hypermotile gastrointestinal sounds were noted on abdominal auscultation. An inflammatory leukogram, dehydration, prerenal azotemia, hyponatremia, hypochloremia, hyperproteinemia, hyperglobulinemia, hypomagnesemia, and high γ-glutamyl transpeptidase activity were identified. Transabdominal ultrasonography revealed distended loops of small intestine.

Treatment—IV fluid therapy and analgesic treatment were unsuccessful in the resolution of clinical signs. Exploratory laparotomy revealed an ileocecal intussusception involving the distal portion of the ileum. Distal ileal and cecal bypass were achieved via side-to-side anastomosis of the proximal portion of the ileum and spiral colon with a gastrointestinal anastomosis stapler. Ileal transection or occlusion was not performed. Postoperative complications were minimal, and the pig was clinically normal 15 months after surgery and required no special care or diet.

Clinical Relevance—Distal ileal and cecal bypass without ileal transection have not been described previously in Vietnamese pot-bellied pigs. Anastomosis of the proximal portion of the ileum to the spiral colon without major complications represents a novel, technically simple approach to bypass of the distal portion of the ileum and cecum.
