Endoscopic Sphincterotomy with Large Balloon Dilation versus Endoscopic Sphincterotomy for Bile Duct Stones: A Systematic Review and Meta-Analysis

Table 1

Baseline characteristics comparing endoscopic sphincterotomy with large balloon dilation (EPLBD) versus endoscopic sphincterotomy (EST).

Trials	Site	Number of patients		Stone size (diameter, mm)		EPLBD procedure		The length of the sphincterotomy
		EPLBD	EST	Range	Mean	Balloon size (mm)	balloon inflated time	EPLBD	EST
Heo et al., 2007 [12]	Korea	100	100	≤40	16.0 ± 0.7 (EPLBD) versus15.0 ± 0.7 (EST)	12–20	60 seconds	Limited to a third size of full length	Complete sphincterotomy
Kim et al., 2009 [13]	Korea	27	28	15–50	20.8 ± 4.1 (EPLBD) versus 20.5 ± 5.7 (EST)	15, 16.5, and 18	Not mentioned	Midportion of the papilla	Complete sphincterotomy
Teoh et al., 2013 [14]	Hong Kong	73	78	Not mentioned	12.47 (5–35) (EPLBD) versus 13.26 (5–40) (EST)	13–15	30 seconds	One-third to one-half of the papilla	Complete sphincterotomy
