ABSTRACT
The term choledocholithiasis refers to a condition when a gallstone or gallstones become lodged within any duct of the bile system. We can find pigment gallstones, cholesterol gallstones and mixed. During surgery to remove the gallbladder you may have a procedure called intraoperative cholangiogram to look for gallstones that may be in the common bileduct. Stones in the bile ducts are classified as either primary (arising the novo), secondary (migrating from the gallbladder), recurrent (reforming after biliary tract surgery) or retained (overlooked at the time of surgery). The prevalence of choledocholithiasis in patients with simptomatic gallbladder lithiasis can be a reason for enlargement of the hospital stay, and eventually in the complexity on the prevented surgical procedure. Our aim was to investigate its prevalence in our Hospital, and the results with the empoyement of the intraoperative cholangiography accordin to our surgical protoco, and the recognized guideliness from other Centers. The results obtained are discused
