1H and 31P NMR analysis on bile, obtained serially following drainage from nineteen patients with extrahepatic malignant biliary obstruction were performed for chief biliary constituents. Based upon absence or presence of cholangitis, patients were classified in two groups. Before drainage median indices of biliary constituents were undetectable in both groups but, recovery following decompression was observed by day 1, with more significance in patients with cholangitis compared to without cholangitis. However, values significantly increased following one week of drainage (P<0.05) in both groups. Suppressed function of transporters during cholestasis is restored following decompression leading to the appearance of biliary constituents.
