Duodenal obstruction caused by malposition of the gallbladder in a heifer.

A heifer with clinical findings suggesting obstruction of the proximal portion of the intestine was admitted for diagnostic evaluation. Ultrasonographic examination of the abdomen failed to locate the gallbladder in its normal anatomic position. Exploratory laparotomy and manual examination of the proximal portion of the intestine revealed obstruction of the duodenum caused by abnormal positioning of the gallbladder. The obstruction was relieved by replacing the gallbladder to its normal position; however, relapse occurred within 2 days. To resolve and prevent the recurrence of the obstruction without compromising gallbladder function, a novel surgical technique to provide fixation of the gallbladder to the liver was performed. The heifer recovered rapidly, proceeded to develop normally during the following year, and became pregnant.
