Abstract:
Objective The study intends to evaluate the extent to which the rapid exchange biliary system(RX system)provides improved efficiency in comparison with conventional guide wire combinations during therapeutic endoscopic retrograde cholangiopancreatography(ERCP).Methods A prospective study was carried out in which 213 patients were randomized to undergo traditional devices(106 patients)or RX system(107 patients).The parameters were recorded in every case,including the wire loss rates,catheter/guide wire exchange times and fluoroscopy times.Results Wires accessing to the desired ductal/strictures were achieved in 97.1% of conventional devices group and 98.1% of RX system group.But in the conventional devices group,the wire loss rates(%)were significantly higher than the rates in RX system group(10.2?2.3 vs 2.4?1.2,P
