Arm 1
Experimental
Single balloon enteroscopy assisted ERCP using a mechanistic loop resolution strategy group
All ERCP was performed with the patient in the prone position using a SBE (SIF-H290S; Olympus Corp., Japan) under CO2 insufflation and conscious sedation. A soft transparent hood (D-201-11804; Olympus Corp., Japan) was used in all cases. The SBE was introduced alternately with an overtube apparatus (ST-SB1S; Olympus Corp., Japan) following the mechanistic loop resolution strategy under endoscopic and fluoroscopic guidance. The overtube was advanced along the enteroscope, by gently pulling the enteroscope, like as ERCP accessory advancement over the guidewire.
