[Value and technique of laparoscopic choledochus revision in choledocholithiasis]

Despite a large scale indication to ERCP, 5% of unsuspected stones are shown by principally intraoperative cholangiography in our patients. Praeoperative diagnostic makes it possible to select the individual optimal therapy for each patient, the possibility of saving the Papilla vateri gives the large scale indication to laparoscopic common bile duct exploration. Also suspected stones gets a one-time cure therapy by complete laparoscopic operation. After balloon-dilatation of cysticus duct to 6 mm, the laparoscopic choledochoscopy is possible through the cysticus duct. Little stones are flushed into the duodenum or extracted by Segura-basket through the cysticus duct. Big stones needs a Laser- or electrohydraulic lithotripsy, the stonefragments can be flushed into the duodenum or aspirated through the cysticus duct. Multiple big or proximal incarcerated stones gives the indication for laparoscopic choledochotomy. Effective extraction is possible by big Segura-basket, residual stones are taken out under choledochoscopic control by little Segura-basket. Incarcerated stones needs the lithotripsy. Microdrainage of the common bile duct and only in special indication the T-tube saves the gall-flow to restitution of papilla function, the common bile duct is closed by running suture in Lahodny-technique. After the regular postoperative cholangiography on third day after operation, the microdrainage can be taken out. In 96% of all laparoscopic cholecystectomies the intraoperative cholangiography was successful. Only 3 of 103 patients needs a postoperative EPT because of residual fragments after trans cystic duct exploration. 8 laparoscopic choledochotomies shows the successness of endoscopic techniques, the postoperative complications can be the same then in conventional operation.
