[Intraoperative cholangiography in laparoscopic cholecystectomy: a simple, cost-effective techniques].

Description of an easy technique to perform an intraoperative cholangiography (IOC) during laparoscopic cholecystectomy at low cost. After puncture of the abdomen in the right hypochondrium with a commercial vein cannula used as a "mini-trocar", this cannula is mounted by an ureteral catheter (UC). By means of the inlying metal-mandrin the UC can be performed in a slightly curved fashion, which permits an easy cannulation of the Ductus cysticus. Furthermore the mandrin prevents an obstruction of the lumen by the metal clip used to fix the UC in the D.cysticus. After withdrawal of the mandrin the IOC can be performed by use of a commercial syringe fitting to the light-blue plastic adapter delivered with the UC. The method is safe, quick and easy and with a price of less than Swiss francs 10.- per IOC it is unrivalled regarding the costs.
