Complete caecal bypass without ileal transection for caecal impaction in horses: seven clinical cases (1997-2007)

To report the clinical outcome in seven horses following use of a newly described surgical technique for treating caecal impaction.

The medical records of seven horses with caecal impaction treated surgically using a stapling technique to create a complete caecal bypass without ileal transection were reviewed. Data were obtained from the records and through telephone interviews with case-associated personnel.

The mean age was 10 years (range 2-22 years) and duration of colic ranged from 24 h to 2 weeks. Five horses had type II motility dysfunction and the remaining two had type I. Mean surgical time was 185 min (range 146-245 min) and the horses were hospitalised for a mean of 12.4 days (range 9-22 days); 71% (5/7) were discharged from hospital and all five were alive 60 days from the surgery date. One horse was lost to follow-up. The four (66.7%) available remaining horses were alive ≥ 1 year (long-term survivors).

Complete caecal bypass without ileal transection for clinical cases of caecal impaction had comparable outcomes to complete bypass with ileal transection. The technique is easy to perform, has the potential to reduce surgical time, compared with traditional bypass techniques, and may reduce the risk of intraoperative abdominal contamination. It is recommended for use in clinical cases in which caecal bypass is desirable.
