Key gastrointestinal surgeries: Intestinal anastomosis
Patients suffering from irresolvable intestinal obstruction or devitalization are among those that benefit from intestinal resection and the procedure described here, which reconnects the intestine end-to-end.


VETERINARY MEDICINE


Anastomosis of the ileum to the distal colon or rectum in cats with megacolon may result in the development of watery feces because of loss of the ileocolic valve, which reduces access of colonic bacteria into the small intestines.3 Additionally, loss of ileum may reduce water absorption capacity of the intestines. Colocolic anastomosis results in more tension across the anastomotic site because the vascular pedicle to the ascending colon is shorter than that to the ileum.3
