Characteristics and clinical outcomes of endoscopic transpapillary gallbladder drainage

Abstract

Objective : This study aimed to analyze the clinical outcomes of therapeutic endoscopic transpapillary gallbladder drainage (ETGBD) and to clarify its characteristics.
Methods : This was a retrospective study where we examined data from 25 patients who had undergone therapeutic ETGBD.
Results : The indications included acute cholecystitis (22 cases ; 88%) , gallbladder bleeding (2 cases ; 8%) , and gallbladder perforation (1 case ; 4%) . The technical success rate was 76% (19 cases) ; we performed endoscopic gallbladder stenting in 13 cases and endoscopic nasogallbladder drainage in 6 cases. The functional success rate in 19 technically successful cases was 84% (16/19 cases) . Adverse events occurred in 2 cases (8%) , one case each of cystic duct perforation and gallbladder perforation.
Conclusion : ETGBD may not be suitable as a therapy for patients with gallbladder bleeding. The indications of ETGBD should be carefully decided.
