摘要
Background and Aims
One of the main reasons for failed endoscopic transpapillary gallbladder stenting (ETGS) under fluoroscopic guidance is the inability to cannulate the cystic duct. Single-operator peroral cholangioscopy (SOC)-assisted ETGS is an adjunct technique to facilitate ETGS. We aimed to demonstrate its efficacy. Methods
Between 2015 and 2019, 104 patients with acute cholecystitis at moderate to high surgical risk underwent ETGS, which involved 3 steps: (1) cystic duct cannulation under fluoroscopic guidance with or without additional SOC guidance; (2) guidewire placement; and (3) stent placement in the gallbladder. The technical success rate was determined when stent placement was confirmed endoscopically and radiographically. Results
Of 104 patients, 55 (53%) patients had successful ETGS under fluoroscopic guidance. Of 49 patients who had failed fluoroscopy-guided ETGS, 41 patients underwent additional SOC-assisted ETGS and 5 patients proceeded to other interventions. Of patients who underwent SOC-assisted ETGS (n = 41), 23 (56%) cystic cannulation followed by stent placement were successful; cystic duct cannulations, guidewire, and stent placement failed in 8, 9, and 1 patients, respectively. The overall technical success rate of ETGS increased from 53% (55 of 104) to 75% (78 of 104) after additional SOC assistance. Adverse events and recurrence were not different between patients who underwent ETGS under fluoroscopic guidance and those who underwent SOC-assisted ETGS. Conclusions
In patients with acute cholecystitis who are not surgical candidates, SOC-assisted ETGS can increase the technical success rate after failed fluoroscopic guidance. SOC can help for the cystic duct cannulation and guidewire placement steps but not for the stent placement step.
