Sealing of cystic duct with bipolar electrocoagulation

Background: 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. Methods: 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. Results: 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. Conclusions: 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.
