title: Efficacy of plain abdominal radiography in patients with biliary tract disease.
abstract: A retrospective review was performed to determine the usefulness of plain abdominal radiographs in patients presenting to the emergency department with gallbladder disease. Patients with the clinical diagnosis of biliary tract disease were divided into two groups: those with confirmed biliary tract disease and those who did not have gall bladder disease. There were no major radiologic findings (pneumoperitoneum, pneumobilia, or bowel obstruction) in any patient with biliary tract disease. No significant difference was noted in the incidence of minor radiologic findings (right upper quadrant calcification, mild ileus and right basilar atelectasis) in patients with biliary colic and acute cholecystitis. Additionally, there was no significant difference in minor findings between patients with biliary tract and nonbiliary tract disease. Plain abdominal radiographic findings were found to be nonspecific in patients with gallbladder disease and not useful in differentiating between patients with biliary colic and acute cholecystitis. Our results also suggest that plain abdominal radiographic findings are not useful in differentiating between patients with and without biliary tract disease, although the selection of patients without biliary tract disease may have biased this finding.
