AIM:To investigate the usefulness of a new rendezvous technique for placing stents using the Kumpe (KMP) catheter in angulated or twisted biliary strictures.METHODS:The rendezvous technique was performed in patients with a biiiary stricture after living donor liver transplantation (LDLT) who required the exchange of percutaneous transhepatic biliary drainage catheters for inside stents.The rendezvous technique was performed using a guidewire in 19 patients (guidewire group) and using a KMP catheter in another 19 (KMP catheter group).We compared the two groups retrospectively.RESULTS:The baseline characteristics did not differ between the groups.The success rate for placing inside stents was 100％ in both groups.A KMP catheter was easier to manipulate than a guidewire.The mean procedure time in the KMP catheter group (1012 s,range:301-2006 s) was shorter than that in the guidewire group (2037 s,range:251-6758 s,P =0.022).The cumulative probabilities corresponding to the procedure time of the two groups were significantly different (P =0.008).The factors related to procedure time were the rendezvous technique method,the number of inside stents,the operator,and balloon dilation of the stricture (P ＜ 0.05).In a multivariate analysis,the rendezvous technique method was the only significant factor related to procedure time (P =0.010).The procedural complications observed included one case of mild acute pancreatitis and one case of acute cholangitis in the guidewire group,and two cases of mild acute pancreatitis in the KMP catheter group.CONCLUSION:The rendezvous technique involving use of the KMP catheter was a fast and safe method for placing inside stents in patients with LDLT biliary stricture that represents a viable alternative to the guidewire rendezvous technique.
