EUS Accuracy Against MRCP for Detection of Pancreaticobiliary Lesions

Özet

Anatomic alterations due to the hepatobiliary system pathologies such as stenosis, dilatation, stone, and tumor can be suspected by clinical symptoms, laboratory tests and eventually confirmed by imaging methods. Both Magnetic Resonance Colangiopathy (MRCP) and Endoscopic Ultrasonography (EUS) are diagnostic tools for etiologic assessment of extrahepatic cholestasis. We aimed to compare MRCP and EUS, about the superiority in diagnostic terms, in our patient group with hepatobiliary system disorders. The results of 135 patients who underwent both MRCP and EUS in the Hospital Gastroenterology Clinic of Mersin University Medical Faculty between 2010-2018 were included in the study. After reviewing the MRCP and EUS reports; stone, tumor and pancreatitis were evaluated and analyzed. Of the patients, 71 (52.6%) were male and 64 (47.4%) were female. The mean age of males was 60.5 ± 15.49 years and that of females was 61.2 ± 14.25. The age spectrum was 23-91 years. In 97 (71.9%) of patients, MRCP and EUS were reported in the same way and both imaging methods led to the correct diagnosis. There were 38 (28.14%) patients with different diagnoses and the total cases with stone, tumor and pancreatitis were evaluated and compared. The sensitivity of EUS for the stone was 88.9% and that of MRCP was 81.5%. The sensitivity of EUS was 92.5% and that of MRI was 66%, in the diagnosis of the tumor and IPMN. In pancreatitis, the sensitivity of EUS was 89.7% and MRCP was 72.4%. EUS is a better diagnostic tool for the diagnosis of choledocholithiasis, tumor and pancreatitis than MRCP.
