[The selective use of intraoperative cholangiography in video laparoscopic cholecystectomy]

Intraoperative cholangiography, a diagnostic method through images introduced in to clinical use in 1932, has recently become a different technical support from that attributed by traditional surgery and it has got a different diagnostic meaning with the introduction of video surgery. The authors used it in 54 of 194 patients submitted to a CVL, always making use of the trans-cystic access, with a percentage of success of 82.6%. It was not possible in 8 patients due to the complete section of the cystic duct during the work (3 cases) and the impossibility of introducing the catheter (5 cases). There is still no common agreement about the opportunity to use IC daily: the authors think selective use is better preceded by a careful clinical laboratory instrumental preoperative study to find patients with the common duct stone. Besides, they are of the opinion that a rigorous surgical technique is fundamental to reduce the lesions of the VBP that there are not in their experience.
