| description | Introduction: Magnetic Resonance Cholangio-Pancreatography
(MRCP) is a non-invasive radiological investigation which can
be performed rapidly and which does not expose the patients
to ionised radiations or iodinated contrast material. The present
study was conducted to evaluate the role of MRCP in detection
of Common Bile Duct (CBD) stones in patients with suspected
choledocholithiasis.
Material and Methods: This prospective study included 30
patients with a suspicion of choledocholithiasis which was
based on clinical evaluation, biochemical or radiological
investigations. Ultrasonography and MRCP were performed
in all patients. All patients underwent open surgery. CBD
exploration was performed in all patients, either due to
presence of palpable stones or due to the presence of dilated
CBD (> 7 mm). Demonstration of CBD stones intra-operatively
was considered the ‘gold standard’ for their presence, defined
as stones visualised and extracted or attempted for extraction
during surgical CBD exploration.
Results: Intra–operatively, 21 (70%) out of 30 patients had
cholelithiasis. 26 (86.67%) out of 30 patients had dilated CBD
stones intra-operatively. In 20 (66.67%) out of 30 patients,
choledocholithiasis was detected intra-operatively. The
sensitivity, specificity, positive and negative predictive value
of ultrasonography in detecting CBD stones in the present
study was 65%, 60%, 76.47% and 46.15% respectively. The
sensitivity, specificity, positive and negative predictive value of
MRCP in diagnosis of CBD stones in the present study was
95%, 90%, 95% and 90% respectively.
Conclusions: MRCP is a non–invasive investigation without
complications and it has high sensitivity, specificity and positive
and negative predictive values in detection of CBD stones.
MRCP should be done in all cases with a suspicion of CBD
stones, where facilities and expertise are available. |
