Theoretical step approach with 'Three-pillar' device assistance for successful endoscopic transpapillary gallbladder drainage.

ABSTRACT:

Background

Endoscopic transpapillary gallbladder drainage (ETGBD) has been reported as an alternative procedure for acute cholecystitis but remains a challenging procedure.

Aims

To elucidate the efficacy of a strategic approach for ETGBD that utilizes a four-step classification system and the optional use of 'Three-pillar' assistance with the following devices: cholangioscopy (SpyGlass DS, SG), a flex-type guidewire (Flex-GW), and a 3-Fr microcatheter (3-Fr Micro).

Methods

A total of 115 patients undergoing ETGBD were studied retrospectively. Characteristics and technical outcomes were compared between conventional ETGBD technique (Classical ETGBD, N = 50) and strategic ETGBD with optional Three-pillar assistance (Strategic ETGBD, N = 65).
