Objective: The aim of this study was to compare predictive factors and Radial Echoendoscopy (EUS) in the diagnosis of choledocholithiasis.
Materials and Methods: Patients with suspected choledocholithiasis were recruited from April 2011 to January 2018. All patient characteristics, findings of EUS and findings of ERCP were recorded and analyzed.
Results: Eighty patients were enrolled in this study. Clinical symptoms, blood chemistry and liver function test were similar in patients with and without choledocholithiasis. Using the findings of ERCP as the gold standard, Radial EUS had sensitivity and specificity for the detection of choledocholithiasis at 90.2% and 97.4%, and for choledocholithiasis and/or common bile duct sludge at 92.7% and 100%, respectively. For patients with intermediate likelihood and high likelihood from predictive factors (33 and 45), Radial EUS was positive for choledocholithiasis in 51.5% (17/33) and 46.7% (21/45), and ERCP was positive for choledocholithiasis in 54.5% (18/33) and 48.9% (22/45), respectively.
Conclusion: Predictive factors, for both intermediate and high likelihood groups, were not accurate to diagnose these patients. Radial EUS is a good diagnostic tool and should done in both groups of patients to avoid unnecessary ERCP.
