A modified technique for extensive large colon resection and anastomosis in horses.

OBJECTIVE

To describe an alternative technique for large colon resection and anastomosis in horses.

STUDY DESIGN

Retrospective study of clinical patients.

ANIMAL POPULATION

37 horses that had ventral midline celiotomies between July 1, 1990, and July 1, 1994.

METHODS

Large colon resection and anastomosis was performed using a modification of previously described techniques. Modifications include mesocolon ligation with a stapling device and an end-to-end apposition of the right ventral and right dorsal colon.

RESULTS

Twenty-one of the 37 horses were discharged from the hospital without complications. Two horses were euthanatized immediately after recovery from anesthesia because of hindlimb fracture. Fourteen horses were euthanatized in the initial postoperative period because of persistent endotoxemia and abdominal pain.

CONCLUSIONS

The described technique is a safe, reliable method for large colon resection and anastomosis in horses.

CLINICAL RELEVANCE

The described technique is fairly simple to perform and requires less surgical time compared with other techniques.
