Large colon resection and anastomosis in horses: 52 cases (1996-2006)

Summary Reasons for performing study: Large colon resection and anastomosis (LCRA) is the most aggressive method of surgical management of a colon with questionable viability. Currently, published studies are comprised mostly of broodmares and discuss short‐term survival. Objectives: To determine the prognosis for survival after LCRA in a diverse population of horses, report the incidence of post operative complications, and determine if associations between analysed variables and survival rate exist. Methods: The medical records of 52 horses that underwent LCRA were evaluated. Data were used to identify univariable associations with survival as well as complications related to LCRA. Chi‐square, odds ratio with 95% confidence interval, Mann‐Whitney or Kruskal‐Wallis tests were used, with significance set at P
