摘　　要：目的 探讨右肝蒂周围肝肿瘤的分型及其意义,为精准肝切除设计切除范围和肝血流阻断方式提供依据.方法 2009年1月至2012年12月我院收治的32例位于右肝蒂周围的单个肝脏肿瘤患者,其中原发性肝癌17例、肝海绵状血管瘤15例.根据其与右肝蒂的毗邻关系分为4型,分别为A型（肿瘤浸润或包绕右肝蒂）、B型（肿瘤位于右肝蒂前侧）、C型（肿瘤位于右肝蒂后侧）和D型（肿瘤位于右肝蒂分叉间）.根据分型设计手术方案,并分别施行不同形式的肝血流阻断和肝切除.结果 肿瘤位置与术前影像学分型完全符合,肝血流阻断方式和肝切除术式与手术规划基本一致.其中右肝蒂浸润型5例,主要施行右半肝或扩大右半肝切除术;右肝蒂前侧型8例,主要施行右前叶或肝中叶切除术;右肝蒂后侧型9例,分别施行肝Ⅴ、Ⅵ段切除术;右肝蒂叉间型10例,分别行肝右前叶或右后叶切除术.肝血流阻断方法有Pringle法、全肝血流阻断术、选择性右侧入肝或出入肝血流阻断术等.所有手术均顺利完成,平均手术时间145 min,平均出血量320 ml,输血18例,平均每例460 ml.术后发生胆漏3例、右侧胸腔积液2例、肝断面出血1例,均经保守治疗而愈.结论 术前运用影像信息对右肝蒂周围肝肿瘤进行分型,可为拟定肝切除范围、选择合适的肝血流阻断方法提供可靠依据,有助于制定更完善的手术方案,完成精准肝切除.Objective To explore the use of the right hepatic pedicle to guide classification of liver neoplasms on medical imaging and the type of liver resection.Methods From January 2009 to December 2012,32 patients with a single liver neoplasm surrounding the right hepatic pedicle,including 17 patients with primary liver cancer and 15 patients with cavernous hemangioma of liver,were recruited into this study in our hospital.Using the position of the neoplasm in relation to the right hepatic pedicle on CT or MRI,these liver neoplasms were divided into 4 types：type A neoplasms which infiltrated or surrounded the right hepatic pedicle; type B neoplasms which were in the front of the right hepatic pedicle; type C neoplasms which were at the back of the right hepatic pedicle,and type D neoplasms which were between the two branches of the right hepatic pedicle.Before surgery,a simulated plan was designed on the different hepatic vascular inflow obstruction and types of hepatectomy based on the classification in medical imaging.Results The locations of the liver neoplasm were completely in line with the preoperative imaging classification.Boththe vascular flow obstruction and the types of hepatectomy correlated with the preoperative surgery simulation planning.Five patients with type A neoplasms underwent right hemihepatectomy or extended right hepatectomy; 8 with type B tumors underwent right anterior sectionectomy or mesohepatectomy; 9 with type C neoplasms underwent segment Ⅴ,Ⅵ resection; 10 with type D tumors underwent right anterior or right posterior sectionectomy.Pringle maneuver,total hepatic blood inflow obstruction and selective right hepatic blood inflow obstruction were applied according to the operation and the regional anatomical structures.All operations were smoothly carried out with an average operation time of 145 min.The average blood loss was 320 ml and 18 patients required intraoperative blood transfusion with an average blood transfusion amount of 460 ml.Postoperative complications included bile leak
