OBJECTIVE In this investigation we compared the diagnostic performance of unenhanced helical CT, oral contrast-enhanced CT cholangiography, and MR cholangiography for the diagnosis of choledocholithiasis. SUBJECTS AND METHODS Fifty-one patients referred for endoscopic retrograde cholangiography of suspected biliary stones were studied with unenhanced helical CT, MR cholangiography, and helica...

Ultrasonography, although an accurate method of detecting stones within the gall bladder, is unreliable for the detection of bile duct stones for which per-operative cholangiography remains the standard investigation. Fifty seven patients undergoing elective cholecystectomy had both a pre-operative intravenous cholangiogram and per-operative cholangiography. The pre-operative investigation is s...

BACKGROUND AND OBJECTIVE Despite the numerous and often cited benefits of routine cholangiography during laparoscopic cholecystectomy, universal application of this technique has not been realized. Surgeons who advocate selective cholangiography cite the extra cost, the low yield of unanticipated findings, and the marked increase in the duration of the operation when cholangiography is added to...

Intraoperative cholangiography was first introduced by Mirizzi in 1931. He recommended its routine use. The debate over the appropriate role of intraoperative cholangiography was renewed by the widespread acceptance of laparoscopic cholecystectomy in 1988. We reviewed our experience to determine the most appropriate use of intraoperative cholangiography. Seven hundred thirty-four consecutive ca...

The value of operative cholangiography in the management of biliary tract disease has been questioned. To better define the role of cholangiography, we reviewed 579 consecutive cholecystectomies done by 1 group of surgeons in a small rural practice over 8 years. Cholangiography demonstrated unsuspected common bile duct disease in 5% of the procedures, while 12% of the patients were spared an un...

Fifty-one patients with suspected obstructive jaundice and 14 without jaundice in whom disease of the biliary tract was suspected but infusion cholangiography had been unhelpful were examined by grey-scale ultrasonography and percutaneous transhepatic cholangiography and the findings analysed retrospectively. Grey-scale ultrasonography distinguished between obstructive and hepatocellular jaundi...

BACKGROUND Intraoperative cholangiography during laparoscopic cholecystectomy reveals the anatomy of the biliary tree and any stones contained within it. The use of intraoperative cholangiography may be routine for all laparoscopic cholecystectomy. An alternative approach is a selective policy, performing intraoperative cholangiography only for those cases in which choledocholithiasis is suspec...

The aim of the work is to assess the performance and effectiveness of intraoperative cholangiography or choledochoscopy in the prevention of choledocholithiasis oversight. The effectiveness of choledochoscopy was assessed in 50 patients during the years 2001-2002. Since 2000 intraoperative cholangiography has been performed on all patients after classic cholecystostomy in the absence of indicat...
