Abstract
Common bile duct (CBD) dilation is a frequent indication for referral for endoscopic ultrasound (EUS). Among asymptomatic individuals, biliary dilation may not be clinically significant, however EUS is often relied upon for exclusion of benign and malignant pathology that might require further intervention. The yield of EUS evaluation for this indication is not well characterized, and has significant implications for health resource utilization, since asymptomatic biliary dilation is prevalent. Through this systematic review, we sought to appraise the yield of EUS evaluation of asymptomatic patients with radiologic evidence of CBD dilation without identifiable etiology.
