    Abstract:
    OBJECTIVE: Bile duct dilation (BDD) of unclear etiology is a common indication for further imaging via endoscopic ultrasound (EUS). We aimed to assess the yield of EUS in determining BDD etiology in patients with prior non-diagnostic imaging studies. METHODS: A retrospective chart review was performed at a single, tertiary-care university hospital for patients referred for EUS for BDD with or without pancreatic duct dilation (PDD). EUS-guided fine needle aspiration (FNA) was performed if a focal lesion was identified. Cases with an etiology of BDD diagnosed or strongly suggested by prior imaging were excluded. EUS findings believed to represent a structural cause for BDD included a wide range of pancreaticobiliary and luminal pathology as well as patients' clinical factors. RESULTS: In total, 307 patients were identified. Findings to explain BDD were found by EUS in 213 patients for a diagnostic yield of 69.4%. Patients with jaundice were significantly more likely to receive a diagnosis by EUS than those without (78.8% vs 55.3%, P < 0.01). Notably, 8.1% of patients with normal liver function test (LFT) had a EUS-diagnosed malignancy. Patients' age, narcotic use, concurrent PDD and prior cholecystectomy did not appear to influence the EUS yield. CONCLUSIONS: EUS continues to play a substantial role in evaluating BDD of unclear etiology, most notably in patients with jaundice. In addition, given that 8.1% of asymptomatic patients without jaundice or abnormal LFT had malignancy diagnosed on EUS, the use of EUS for BDD of unclear etiology remains warranted.
