AbstractBackground and Aims

The recent development of EUS-guided gallbladder drainage (EGBD) with a lumen-apposing stent has made endoscopic assessment and advanced gallbladder interventions via the stent possible. The aim of this study was to assess the feasibility and safety of per-oral cholecystoscopy and the types of gallbladder interventions that can be performed.

Methods

This was a retrospective review conducted in the Prince of Wales Hospital from June 2012 to March 2016. All patients who had acute cholecystitis with EGBD were included. Cholecystoscopy was performed 1 to 3 months after stent insertion. Patients’ demographic data, technical success, types of intervention, and adverse events were recorded.

Results

Twenty-nine cholecystoscopies were performed in 25 patients. Twenty-seven of 29 cholecystoscopies were successful (93.1%). Magnifying endoscopy was performed in 10 patients, confocal endomicroscopy and EUS in 1 patient, and endocytoscopy in another patient. Fourteen patients (56%) had spontaneous stone passage. Eleven patients (44%) had residual gallstones on cholecystoscopy, and removed in 8. Overall stone clearance rate was 88% after a mean (standard deviation) number of 1.25 (0.46) sessions of cholecystoscopy.

Conclusions

Per-oral cholecystoscopy and advanced gallbladder interventions were feasible and safe. This opens up exciting possibilities for endoscopic treatment of gallbladder pathologies.
