腹腔鏡下胆嚢摘出術における胆管損傷6例について原因,予防および対処法を中心に検討を行った.原因は解剖学的誤認によるものが4例(完全離断1例,部分損傷3例)と多く,剥離操作による穿孔損傷が2例であった.術中胆道造影は全例に行われていた.完全離断例に対して胆管胆管端々吻合術を施行したが,縫合不全を生じ約5か月後に吻合部狭窄のためステント留置に至った.胆管損傷の予防には胆道系の解剖を十分に把握することが重要で,特に術中胆道造影は胆管損傷の早期発見と重症化の防止に有用であると思われた.完全離断例に対する術式の選択は慎重にすべきであると考えられる.
We investigated the causes, prevention and management in 6 cases of biliary injuries that occurred during laparoscopic cholecystectomy. Causes of the injuries included disorientation of surgical anatomy in 4 cases (1 with complete transection, 3 with partial injury), and inappropriate operative maneuvers in 2. Intraoperative cholangiography was performed in all cases. End-to-end anastomosis of the bile duct was performed for com-plete transection, but anastomotic stricture resulted approximately 5 months later due to failure of the suture, which was treated by expandable stent placement.
