Abstract:
Objective To explore the feasibility of gallbladder mucosal ablation by hysteroscopic rollerball electrocoagulation after cholecystostomy.Methods Under epidural or general anesthesia combined with local anesthesia,20 patients were examined and treated with hysteroscopy after cholecystostomy.After inserting a Storz endoscope,the epithelium of the proximal cystic duct and the mucosa of the gallbladder were ablated with the roller-ball and roller-barrel electrodes respectively.The electrocoagulation power was set at 60-70 W with the roller-barrel excursion rate between 10-15 mm/s,which makes the inner wall of the cyst homogenously brown-grey.Results The mean endoscopic operation time was 35 minutes(range: 25-55).Among the patients,the gallbladder lumen was completely obliterated within one month in 12 patients,and within 3 months in 5;3 patients developed retention cysts.Conclusion Endoscopic electrocoagulation of the cholecystic mucosa is feasible for obliteration of the gallbladder.
