An observational study in Choledocholithiasis, sponsored by Gangnam Severance Hospital. Completed. Open to participants aged 20 Years to 90 Years. Per ClinicalTrials.gov, last updated 2021-02-03.
Sponsored by Gangnam Severance Hospital · Observational
Laboratory change induced by common bile duct (CBD) stone is in general observed as the higher elevation of alkaline phosphatase (ALP) and gamma-glutamyl transpeptideas (ɤ-GT), in comparison to those of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). However, some patients with CBD stone show the marked increased level of aminotransferase, which sometimes leads to misdiagnose those as liver disease caused by viral hepatitis, ischemia, and drug toxicity. The aim of this study is to investigate the clinicopathologic features of patients with CBD stones with the high level of aminotransferase in serum.

"Patients have been diagnosed as CBD stone under endoscopic retrograde cholangiopancreatography (ERCP). Among patients, patients who displayed above 400 IU/L of aminotransferase without cholangitis (gallstone hepatitis group) and patients who showed the normal value of aminotransferase (control group) were enrolled in this study. We estimated two groups by comparing clinical features, lab finding, radiologic images, and findings under ERCP such as CBD diameter, CBD stone diameter, CBD stone number, periampullary diverticulum.
Exclusion Criteria:
gallstone hepatitis group (Among patients diagnosed as CBD stone who displayed above 400 IU/L of aminotransferase without cholangitis),
control group (Among patients diagnosed as CBD stone who showed the normal value of aminotransferase)
clinicopathologic features of patients with CBD stones with the high level of aminotransferase
lab finding, radiologic images, and findings under ERCP such as CBD diameter, CBD stone diameter, CBD stone number, periampullary diverticulum.
