Abstract: ［Abstract］Objective〖HTSS〗To explore the safety and feasibility of anatomical hepatectomy for severe liver trauma.
〖HTH〗〖WTHZ〗Methods〖HTSS〗Retrospective analyzed of clinical data of 20 patients with severe liver trauma after anatomical hepatectomy. The all patients underwent anatomical hepatectomy with pringle′s maneuver or regional hepatic portal occlsion. Operation time,intraoperative blood loss， and perioperative complications were observed.
〖HTH〗〖WTHZ〗Results〖HTSS〗All the 20 cases underwent anatomical hepatectomy successfully.The operations included left lateral lobectomy(n=4),right anterior lobectomy(n=2), segment Ⅶ hepatectomy(n=2), segment Ⅴ hepatectomy(n=3), segment Ⅵ hepatectomy(n=3), segment Ⅳb hepatectomy(n=3),left hemihepatectomy(n=1)， right hemihepatectomy(n=2). One of cases combined with posthepatic inferior vena cava injury underwent inferior vena cava repair successfully when anatomical right hemihepatectomy. Four cases with different degrees of biliary injury underwent repair and T tube drainage during the operation.The operation time was 2-6 h. The intraoperative blood loss was 300-1 000 mL. 1 case suffered from bile leakage after operation,and 2 cases suffered from subphrenic infection and 2 cases suffered from pulmonary infection,1 case suffered from introabdominal hemorrhage after operation. All recovered after symptomatic treatments.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗The treatment of severe liver trauma is not only emphasis on hemostasis, on the premise of ensuring the stability of vital signs, but also the prevention of postoperative complications. Anatomical hepatectomy is one of the safe and effective surgical methods in the treatment of severe liver trauma.
