Benefits of endoscopic gallbladder stenting following percutaneous transhepatic gallbladder drainage

Endoscopic transpapillary gallbladder drainage is challenging because of the complexity of the procedure and high incidence of adverse events (AEs). To overcome these problems, endoscopic gallbladder stenting (EGBS) after percutaneous transhepatic gallbladder drainage (PTGBD) can be effective, as it mitigates inflammation and adhesion.

To examine the benefits of EGBS after PTGBD to assess its efficacy and impact on AEs.

We retrospectively analyzed data from 35 patients who underwent EGBS after PTGBD at a single center between January 2016 and December 2023. The primary outcomes were technical success and AEs, and the rate of recurrent cholecystitis was evaluated. In addition, the reasons for the failure of the procedure were identified.

Among the 35 patients, the technical success rate was 77.1% and the final contrast of the cystic duct was successful in 97.1% of patients. The incidence of early AEs was relatively low (11.4%), with no instances of cystic duct perforation. The rate of recurrent cholecystitis was 3.7%, and no other biliary events were observed.

EGBS after PTGBD may be significantly beneficial, with a substantial success rate and minimal AEs in both short- and long-term follow-ups.
