胆囊造口后内镜下电凝胆囊粘膜消除术

Obliteration of the gallbladder mucosa by endoscopic electrocoagulation after cholecystostomy

目的 :对内镜下电凝消除胆囊管及胆囊粘膜的效果进行评估。方法 :12例胆囊造口术后病人在硬膜外麻醉下行宫腔镜检查和治疗。分别用滚球和滚棒电极电凝消除胆囊管及胆囊粘膜 ,电凝功率为6 0～ 70W ,滚棒移动速度为 10～ 15mm/s。结果 :内镜下操作时间为 2 5～ 5 5min (平均 35min) ,术后 6个月内胆囊腔完全闭合者 8例 ,其余未闭合者胆囊已萎缩。结论 :内镜下电凝消除胆囊管及胆囊粘膜是胆囊造口后一期胆囊硬化闭塞的可行方法。

Objective:To evaluate a method of gallbladder mucosa obliteration by endoscopic electrocoagulation. Methods:Twelve patients after mini-cholecystostomy have been treated with histeroscopy under epidural anesthesia. The mucosae of the cystic duct and gallbladder were ablated with the roller ball and the roller bar electrodes respectively. The electrocoagulation power was 60～70W with the roller bar moving speed of 10～15mm/s.Results:The manipulation under the endoscope took 25～55 minutes (average 35min). Eight patients had their gallbladders completely sclerosed in six months of the manipulation. The others who were under 4 months or 6 months follows up had all the gallbladders shrunken. Conclusion:Endoscopic electrocoagulation is a practical single phase method for ablation of the gallbladder.
