The cystic duct leakage rate is still high. The aim of this study was to evaluate an alternative technique for securing the cystic duct using the Ligasure vessel sealing system.
Eight pigs were included in this pilot study. We performed a cholecystectomy, using the Ligasure system to sealing the cystic duct and artery. The pigs were killed 8 days after operation, and specimens of the cystic duct and common bile duct were removed for pathologic examination.
There were no clinical complications other than two superficial wound infections. The sealing of the cystic duct and artery were both macroscopically and microscopically 100% sufficient. The maximum extension of the coagulative process in the sealed ducts was 0.25 mm on each side of the sealed area.
The Ligasure system seems promising for securing the cystic duct and artery during cholecystectomy. Future studies should evaluate safety with this technique on a larger scale.
胆囊管漏出率仍然很高。本研究的目的是评估一种使用Ligasure血管闭合系统固定胆囊管的替代技术。
八头猪纳入了这项初步研究。我们进行了胆囊切除术，使用Ligasure系统闭合胆囊管和动脉。术后8天处死猪，并取出胆囊管和胆总管标本进行病理检查。
除两例表浅伤口感染外，无其他临床并发症。胆囊管和动脉的闭合在宏观和微观上均100%充分。在闭合管道中，凝固过程在闭合区域两侧的最大延伸为0.25毫米。
Ligasure系统在胆囊切除术中固定胆囊管和动脉方面似乎很有前景。未来的研究应更大规模地评估该技术的安全性。
