Abstract
This retrospective study presents the results of surgical treatment of obstructive colic in horses operated in the last decade (1976–1985). The overall short‐term recovery rate (i.e. discharged from hospital) was 51% of cases presented for surgery, and 68% of cases which were considered to be amenable to surgical therapy. For long‐term results (6 months ‐ 8 years follow up) these percentages must be reduced by about 15% due to mortality after discharge. Special attention has been given to surgery of the ileum, which is often involved in strangulation or obturation, and accounts for about 26% of gastrointestinal surgical disorders. The long‐term recovery rate of ileal surgery was 54.3%, but ileocaecal intussusception and jejunocaecostomy with resection have a much poorer prognosis. The results of this study indicate that resection of the ileum should be avoided unless necrosis is present or threatening. The alternative is creation of a shunt between (distal) jejunum and caecum, thus bypassing the ileum and ileocaecal junction and preserving the original anatomical relationships.
