Abstract
patients) and the ESBD groups (60 patients). There were no significant differences in background demographics. 39 patients had prior history of endoscopic sphincterotomy (P 0.825). The mean (S.D.) size of the largest common bile duct stone was 12.87 (7.11) and 12.53 (5.07) mm respectively (P 0.82). There were no differences in the rate of stone clearance during the index ERCP for all stones (90.9% vs 86.67%, P 0.435) and for stones that were 1.5cm (85% vs 80%, P 0.25). However, significantly more patients in the ES group required the use of the BML to complete stone extraction (45% vs 28.3%, P 0.047). Complications occurred in 18.2% and 20% of the patients respectively (P 0.795) and there were no differences in the rates of postsphincterotomy bleeding amongst the 2 groups (10.6% vs 8.35%, P 0.66). There were no procedure-related mortalities.Conclusions:Combined sphincterotomy and balloon dilation enables the retrieval of large common bile ducts stones with reduced need of the BML. The procedure can achieve high rates of complete stone clearance with comparable rates of morbidities to standard sphincterotomy.
