Six enterotomies 3 cm long, spaced at 3 cm intervals, were made in the antimesenteric border of the pelvic flexure of the ascending colon in five adult horses. Ten incisions each were sutured with a Utrecht pattern (single layer), a full‐thickness simple continuous oversewn with a Cushing pattern (two layer), and a mucosal simple continuous with a seromuscular simple continuous oversewn with a Cushing pattern (three layer). In all horses, chromic gut and polyglactin 910 were each used once for each pattern. On day 6, the pelvic flexure was excised and the colonic vessels were injected with a radio‐opaque mass. Sections of each enterotomy were studied by light microscopy and high detail radiography. The single‐layer closure led to serosa‐to‐mucosa healing and a thin bowel wall, and the three‐layer closure resulted in distortion of the bowel wall by hematoma formation and submucosal contamination with ingesta. The two‐layer closure resulted in good alignment and improved healing. There was less inflammatory reaction with polyglactin 910 than with chromic gut.
