Direct peroral cholangioscopy using an ultrathin endoscope: making technique easier

| description | Background: Cholangioscopy is a useful tool for the study and treatment of biliary pathology. Ultrathin upper endoscopes allow direct peroral cholangioscopy (DPC) but have some drawbacks. Objective: The aim of the study was to evaluate the success rate of DPC with an ultrathin endoscope using a balloon catheter to reach the biliary confluence. Material and methods: Prospective observational study. An ultrathin endoscope (Olympus XP180N, outer diameter 5.5 mm, working channel 2 mm) was used. To access the biliary tree, free-hand technique was used. To reach the biliary confluence an intraductal balloon catheter (Olympus B5-2Q diameter 1.9 mm) and a 0.025 inch guide wire was used. In all cases sphincterotomy and/or sphincteroplasty was performed. The success rate was defined as the percentage of cases in which the biliary confluence could be reached with the ultrathin endoscope. Results: Fifteen patients (8 men/7 women) were included. Mean age was 77.7 ± 10.8 years (range 45-91). The indications for cholangioscopy were suspected bile duct stones (n = 9), electrohydraulic lithotripsy for the treatment of difficult choledocholithiasis (n = 5) and evaluation of biliary stricture (n = 1). Access to the bile duct was achieved in 14/15 cases (93.3 %). Biliary confluence was reached in 13/15 cases (86.7 %). One complication was observed in one patient (oxigen desaturation). Conclusions: DPC with an ultrathin endoscope can be done with the free-hand technique. Intraductal balloon-guided DPC allows full examination of the common bile duct in most cases. |
