PDFAbstract
Objective To explore the diagnostic effects of computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasonography (EUS) in the diagnosis of choledocholithiasis. Methods The clinical data of 114 patients which suspected as choledocholithiasis by ultrasound were analyzed retrospectively. The patients were divided into CT group (n=37), MRCP group (n=45) and EUS group (n=32) according to the follow-up examination methods. Endoscopic retrograde cholangiopancreatography (ERCP) was used as the gold standard to analyze the consistency and diagnostic coincidence rate of the three groups. Results The choledocholithiasis ratios diagnosed by ERCP in the three groups were 54.05% (20/37), 57.78% (26/45) and 65.62% (21/32) respectively (P>0.05). The coincidence rates of the three groups in the diagnosis of choledocholithiasis were 85.00% (32/37), 88.46% (41/45) and 93.75% (30/32) respectively (P>0.05), and they were well consistent with ERCP in the diagnosis of choledocholithiasis (Kappa>0.70). Conclusion CT, MRCP and EUS have ideal efficacy in the diagnosis of choledocholithiasis, and the method can be flexibly selected for patients in clinical practice.
