BACKGROUND: Endoscopic visualization of gallbladder lesions by the traditional peroral cholangioscopy (POCS) during the endoscopic retrograde cholangiopancreatography process is challenging. In the present study, we evaluated the feasibility of a newly designed POCS with an ultrafine outer diameter that facilitates gallbladder visualization.
METHODS: The novel POCS was designed and manufactured with an outer diameter of 7 French and achieved extremely high performance. The feasibility of this novel POCS for gallbladder observation was assessed in our center between April 2022 and January 2023. The primary outcome was technical success.
RESULTS: A total of 16 patients (64.6 ± 18.1 years, 9 males) who underwent novel ultrafine POCS inspection for gallbladder visualization were included. Technical success was achieved in 14 of 16 cases (87.5%); the main reasons for the two unsuccessful inspections were the presence of cystic duct strictures. A total of 1 adverse event occurred, for an overall rate of 6.3%, and there were no serious adverse events during the follow-up.
CONCLUSIONS: The results suggest that endoscopic visualization of the gallbladder using the novel ultrafine POCS is feasible. The device is expected to provide a new direction for the management of gallbladder disorders in the future.
