Background
Endoscopic papillary large balloon dilation (EPLBD) is safe and effective in management of common bile duct stones (CBDS). Endoscopic sphincterotomy (EST) prior to EPLBD has been performed as a standard procedure. However, the significance of EST prior to EPLBD has not been well studied yet.
Aims
To compare the clinical outcomes of EPLBD with and without EST to evaluate the significance of EST.
Methods
Between April 2010 and March 2015, a total of 82 patients with naïve papillae underwent EPLBD with or without EST for the management of CBDS. A retrospective analysis compared the efficacy and safety of EPLBD with and without EST.
Results
Basic patient characteristics were not significantly different between the groups that underwent EPLBD with EST (n = 27) and without EST (n = 55). Complete stone removal rates were similar between the groups (100 % in the EST group and 98 % in the non-EST group, p = 1.00). There was no significant difference in the median balloon size (13 mm in both groups, p = 0.445), rate of application of mechanical lithotripsy (26 vs. 35 % in the EST and non-EST groups, respectively, p = 0.463), or the median procedure time (38 vs. 34 min in the EST and non-EST groups, respectively, p = 0.682). The overall adverse event rates were not statistically different (4 vs. 7 % in the EST and non-EST groups, respectively, p = 1.00). Pancreatitis, cholangitis, and hemorrhage rates were also similar in both groups.
Conclusions
EST prior to EPLBD may be unnecessary since this study did not demonstrate its benefits.
