Abstract

Background: Primary bile duct stones are a common surgical disease in Viet Nam. Computer tomography can be used to evaluate biliary lithiasis, helping to choose a reasonable treatment and monitoring strategy. Objectives: Describe computer tomography characteristics of biliary lithiasis and determine the value of computer tomography in diagnosing hepatic main biliary stones. Materials and methods: A cross-sectional descriptive study was conducted on 132 patients at Can Tho General Hospital who were suspected of having bile duct lithiasis based on clinical symptoms were examined with computed tomography scan with contrast. The presence or absence of biliary lithiasis was confirmed on the basis of findings at surgery and/or intraoperative cholangiography or endoscopic retrograde cholangiography. Results: Patients over 60 years old accounted for the majority (62.1%), the female: male ratio was 1.36:1, history of treatment for biliary stones was 40.9%. Among the main hepatic biliary stones according to computer tomography results, choledocholithiasis with high proportion. The main hepatic biliary stone dimension, is mostly ≥ 10 mm, most attenuation 50-149 HU. Sensitivity, and specificity in the main hepatic biliary stone diagnosis through computer tomography ≥ 80%. Conclusions: Computed tomography has a high value in the diagnosis of hepatic main biliary stones.
