A technique for nasobiliary draining and sanitization of the bile ducts in cholangitis and recurrent choledocholithiasis comprises use of fibroduodenoscope, draining tube, and fistulography. The tube is inserted into hepatocholedoch, and several loops are formed from it. Upon fistulography, fibroduodenoscope is removed, the tube is fixed, and hepatocholedoch is sanitized.
