[Role of intraoperative cholangiography in videolaparoscopic cholecystectomy]

Laparoscopic cholecystectomy represents elective the treatment of symptomatic lithiasis of gallbladder, due to advantages of shorter hospitalization and lower cost. The evolution of technological instruments permits today an easy and rapid execution of intraoperative cholangiography (IC). Therefore the elective or selective application of IC is debated, because of the effective determination of iatrogenic lesions and the real possibility of diagnosis for unknown lithiasis of biliary tract. Some authors agree that anatomic lesions cannot be prevented by IC, because 50% of its occur during the surgical dissection to prepare structures of Calot's triangle to make cholangiography. On the other hand the early diagnosis of iatrogenic lesions is fundamental for the results. The previous biliary symptomatology (jaundice), the elevation of biochemical parameters of biliary function (bilirubinemia, transaminase and alkaline phosphatase) and the dilatation of biliary ducts represents the indication to IC. The examination is also recommended in case of difficulties of dissection due to inflammatory process, to clarify the anatomy with more safety. Finally, the technique is well defined. The choice of patients is made on the basis of surgeon's opinions but we think that a good selection of patient is the only chance to perform IC with the best results.
