Duodenal perforation and abdominal abscess in a cow.

A mature Jersey cow developed duodenal perforation and localized abscessation. After failure of a right flank marsupialization procedure, a side-to-side duodenojejunal anastomosis was created. The duodenum distal to the anastomosis was ligated and the original duodenal fistula was closed with chromic gut sutures. The abscess cavity was sutured to the right lateral body wall for drainage, and the cow recovered slowly.
