Comparison of clinical value of ultrasonography, MSCT and MRCP in early diagnosis of cholelithiasis / 中国基层医药

ABSTRACT

Objective:To compare the clinical value of ultrasonography, multi-slice spiral computed tomography(MSCT) and magnetic resonance cholangiopancreatography(MRCP) in the early diagnosis of cholelithiasis.Methods:The clinical data of 140 patients with suspected cholelithiasis treated in Yuyao People's Hospital from January 2017 to March 2019 were reviewed.All the patients were examined by ultrasonography, MSCT and MRCP.Based on the results of operation, the diagnostic results of ultrasonography, MSCT and MRCP were compared, and the consistency between the diagnostic results was analyzed.Results:Of 140 patients with suspected cholelithiasis, 100 cases were confirmed to be cholelithiasis by operation.The sensitivity, specificity and accuracy of MRCP were 97.00%(97/100), 95.00%(38/40) and 96.43%(135/140), which were higher than those of ultrasonography[87.00% (87/100), 80.00%(32/40), 85.00%(119/140)] and MSCT[89.00%(89/100), 77.50%(31/40) and 85.71%(120/140)](χ 2=6.794, 4.114, 10.854, χ 2=4.916, 5.165, 9.882, all P<0.05). The consistency between MRCP and surgical diagnosis was good, but the consistency between ultrasound, MSCT and surgical diagnosis was moderate. Conclusion:The accuracy of MRCP is better than ultrasound and MSCT in the diagnosis of cholelithiasis, which has good diagnostic value and can reduce the missed diagnosis and misdiagnosis of cholelithiasis.
