Hospital Physician, 06/23/09
Venkat A et al. - Gallstone ileus is a complication of either acute or chronic cholecystitis and is responsible for approximately 25% of nonstrangulated bowel obstructions in patients over age 65 years. Clinical findings are nonspecific and may include abdominal pain, nausea, bilious emesis, and elevated aminotransferase levels. In this case, the deceptively normal liver function tests may have resulted from the gallstone not migrating through or obstructing the biliary tree and continued biliary drainage through the fistula and the ampulla. Computed tomography is the most appropriate diagnostic imaging modality for gallstone ileus, with 1 study showing sensitivity of 93% and specificity of 99%.
