A retrospective study comparing the outcome of horses undergoing small intestinal resection and anastomosis with a single layer (lembert) or double layer (simple continuous and cushing) technique

Abstract

Objectives: To (1) compare postoperative complications and survival in horses after small intestinal resection and anastomosis using 2 anastomosis techniques (single layer Lembert; double layer simple continuous oversewn with Cushing), and (2) to compare outcome by anastomosis type (jejunoileostomy; jejunojejunostomy). Study Design: Retrospective case series. Animals: Horses (n=53). Methods: Medical records (July 2006-July 2010) of all horses that had small intestinal resection and anastomosis. Horses were divided into groups based on technique and type of anastomosis. Comparisons of pre- and intraoperative findings (disease severity), postoperative complications, and survival rates were made between groups. Results: There were no differences in disease severity, postoperative complications, or survival between single layer (n=23) or double layer (n=31) anastomoses. There were no differences in disease severity or survival between jejunoileostomy (n=16) or jejunojejunostomy (n=38). There was a higher incidence of postoperative colic in hospital after jejunoileostomy (13/16) compared with jejunojejunostomy (18/38) (P= 0127). Conclusions: Postoperative complications and survival are comparable between horses undergoing single layer and double layer small intestinal end-to-end anastomoses. With the exception of increased postoperative colic in the hospital, postoperative complications and survival after jejunoileostomy and jejunojejunostomy are also comparable. © 2014 by The American College of Veterinary Surgeons.
