Endoscopic papillary balloon dilation: Revival of the old technique

Table 1 Comparison of endoscopic balloon dilation methods according to balloon diameter

	Small-balloon EPBD	Large-balloon EPBD
Balloon diameter used	≤ 10 mm (6-10 mm)	≥ 12 mm (12-20 mm)
Target stone	Small to moderate sized stones in no or minimally dilated CBD	Large stones in considerably dilated CBD
Endoscopic biliary sphincterotomy	Not performed	Mostly, in conjunction with a small EST1

¹Preceding small-endoscopic biliary sphincterotomy (EST) use may shift the expansile force more toward the common bile duct (CBD) rather than the pancreatic orifice. EPBD: Endoscopic papillary balloon dilation.
