Retrospective evaluation of repeat celiotomy in 53 horses with acute gastrointestinal disease.
Fifty-three of 648 horses (8.2%) treated surgically for acute gastrointestinal obstruction were subjected to repeat celiotomy. Forty horses (75%) recovered from anesthesia after repeat celiotomy, and 26 horses (49%) were discharged from the clinic. Excluding two horses lost to follow-up, 10 of 51 horses (20%) survived long term. Horses subjected to repeat celiotomy had a significantly lower long-term survival rate than horses subjected to a single celiotomy. Twenty-eight horses had mechanical obstructions, and 22 had functional obstructions at the second surgery. Significantly more horses with mechanical obstructions recovered from anesthesia, but there was no difference in short-term or long-term survival. Seventy-seven percent of horses were subjected to two celiotomies without being discharged from the clinic between procedures. The intervals between primary and repeat celiotomies ranged from less than 24 hours to 4 years, with 89% of them being less than 2 months. Horses with functional obstructions at the second surgery had a significantly shorter interval between surgeries than horses with mechanical obstructions. Twenty-three horses had sequelae of the primary celiotomy, 19 had progression of their original disease, 8 had recurrence of the same condition, and 3 had unrelated problems. Intestinal ischemic necrosis was the most common diagnosis at repeat celiotomy, and small intestinal obstruction by adhesions was the second most frequent.
