ABSTRACT

 

Aim: To determine the diagnostic accuracy of MRCP in diagnosing choledocholithiasis taking operative findings as gold standard.

Study design: Descriptive, Cross-sectional study.

Settings: Department of Radiology, BVH, Bahawalpur.

Study duration:  May 2016 to November 2016

Methodology: A total of 138 patients with obstructive jaundice for >7 days on lab analysis of age 20-60 years of either gender were included. Patients with coagulation disorder and absolute contraindication to MRCP were excluded. After taking informed consent, MRCP was performed in every patient. Surgery was performed. MRCP findings were compared with operative findings.

Results: MRCP supported the diagnosis of choledocholithiasis in 76 (55.1%) patients. Operative findings confirmed choledocholithiasis in 72 (52.2%) cases. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of MRCP in diagnosing choledocholithiasis taking operative findings as gold standard was 90.3%, 83.3%, 85.5%, 88.7% and 86.9% respectively..

Conclusion: Magnetic resonance cholangiopancreatography is the non-invasive modality of choice with high diagnostic accuracy in diagnosing choledocholithiasis.

Keywords: Choledocholithiasis, magnetic resonance cholangiopancreatography, sensitivity.
