Volvulus of the large colon in the horse

Volvulus of the large colon was diagnosed at surgery in 25 horses during a 4-year period. Two horses had a recurrence of the condition after successful correction. Mucosal necrosis was found to be a grave prognostic sign, as it was a consistent finding in horses that died at the time of surgery. Long-term colon dysfunction was not clinically evident in surviving horses.
