Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central Telephone Number - random allocation once common bile duct stones are identified at operative cholangiogram.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence was generated with a computer program, in blocks. Patients are stratified at the time of randomisation according to whether or not the surgeon attempted to explore the common bile duct transcystically but failed to clear it.
Masking / blinding
Open (masking not used)

Summary
Brief summary
This study is designed to assess whether a new technique called facilitated endoscopic retrograde cholangiopancreatography (ERCP) is or is not superior to conventional ERCP to remove stones found in the bile duct at the time of laparoscopic cholecystectomy. ERCP is an endoscopic procedure used to facilitate the radiological examination and subsequent manipulation of the common bile duct (eg. opening it up, which is called sphincterotomy). Both facilitated and conventional ERCP are performed as a separate procedure after the initial gallbladder surgery. This is a comparative study of these two techniques in a randomised clinical trial.

The aim of this randomised clinical trial is to enable surgeons to decide whether placement of a plastic stent at the time of laparoscopic cholecystectomy will improve the success rate and safety of subsequent ERCP and sphincterotomy.
