Challenging diagnosis--icterus associated with a single perforating duodenal ulcer after long-term nonsteroidal antiinflammatory drug administration in a dog.

ABSTRACT

A dog developed icterus, vomiting, and anorexia 2 wk after orthopedic surgery and treatment with meloxicam for approximately 1 y. Exploratory laparotomy revealed a single perforated duodenal ulcer. The most likely cause of the hyperbilirubinemia was intrahepatic cholestasis resulting from peritonitis associated with the perforation.
