Background: Early cholecystectomy is the standard therapy for acute cholecystitis. In critically ill elderly patients, however, the mortality rate of emergency cholecystectomy can reach 30%. Several reports have described the usefulness of percutaneous transhepatic gallbladder drainage (PTGBD) or percutaneous transhepatic gallbladder aspiration (PTGBA) for such poor surgical candidates. Recently, endoscopic transpapillary naso-gallbladder drainage (ETGBD) and endoscopic gallbladder stenting (EGS) have been reported to be useful in patients with acute cholecystitis for whom a percutaneous approach is contraindicated. Objective: To evaluate the efficacy of permanent EGS for management of acute cholecystitis in elderly patients who are poor surgical candidates. Design: Retrospective study. Setting: Japan Labour Health and Welfare Organization Niigata Rosai Hospital. Patients: Forty-six elderly patients with acute cholecystitis who were 65 years of age or older. Interventions: All patients underwent EGS. A 7Fr double pig-tail stent was inserted into the gallbladder. If EGS failed, PTGBD or PTGBA was performed subsequently. Main outcome measurements: The efficacy of EGS. Results: EGS was successful in 37 patients (80.4%) without immediate postprocedural complications, and performed permanent EGS was applied in 31 patients. In 30 of these 31 patients (96.7%), there was no recurrent cholecystitis and 29 patients (93.5%) remained asymptomatic for the duration of their survival (from 1 month to 5 years). Limitations: Difficulty of the EGS procedure. Conclusions: EGS can be effective for elderly patients with acute cholecystitis who are poor surgical candidates and can maintain them for up to several years.
