Objective To compare survival and complications in horses undergoing large colon resection with either sutured end‐to‐end or stapled functional end‐to‐end anastomoses. Study design Retrospective cohort study. Animals Twenty‐six client‐owned horses with gastrointestinal disease. Methods Retrospective data were retrieved from the medical records of 26 horses undergoing colectomy, including 14 horses with sutured end‐to‐end and 12 horses with stapled functional end‐to‐end anastomoses, between 2003 and 2016. Records were evaluated for signalment, medical and surgical treatments, and survival to hospital discharge. Long‐term follow‐up was obtained through owner contact. Continuous variables were compared with Mann‐Whitney tests. Fisher's exact testing was used to compare survival to hospital discharge. Survival time was compared by constructing Kaplan‐Meier survival curves and performing log‐rank curve comparison testing. Results Mean age of horses undergoing colectomy was 13 years. Reason for colectomy was prophylaxis (12) or salvage (14). Mean surgical time was 169 minutes. Mean hospitalization time was 9 days, which did not differ with anastomosis type ( P = .62). Nine of 12 horses undergoing stapled functional end‐to‐end anastomosis and 12 of 14 horses undergoing sutured end‐to‐end anastomosis survived to hospital discharge ( P = .63). Survival time did not differ with anastomosis technique ( P = .35). Conclusion Short‐ and long‐term survival outcomes are not different between sutured end‐to‐end or stapled functional end‐to‐end anastomoses in horses undergoing colectomy.
