手术切除治疗肝尾状叶巨大肿瘤的病例对照研究

目的 探讨肝尾状叶巨大肿瘤的手术疗效及最佳手术方法.方法 对2001年1月至2007年6月,东方肝胆外科医院手术治疗的33例肝尾状叶巨大肿瘤(≥10 cm)患者资料进行回顾性分析.对单独尾状叶切除与联合切除病例的临床病理特征、手术结果、并发症、远期生存率进行比较.结果 33例患者中15例(45.5％)接受了全部或部分尾状叶切除,18例(54.5％)接受了全部或部分尾状叶切除联合部分肝切除.手术切除最常用于原发性肝癌(HCC)(51.5％)、其次为血管瘤(21.2％)、肝内胆管癌(9.1％)、血管平滑肌脂肪瘤(6.1％)、肝腺瘤(3％)、局灶性结节性增生(3％)、结肠癌肝转移(3％)和肉瘤(3％).肿瘤的平均直径为12.3(范围10.2～21)cm.与联合肝尾状叶切除术比较,单纯尾状叶切除患者有较长的手术时间(280 min比170 min)及住院天数(17 d比12 d),失血量较多(1250ml比670 ml).两组病例均无围手术期死亡.单纯肝尾状叶切除术与联合肝尾状叶切除术两组患者的并发症发生率为别为26.7％与16.7％.恶性病变组患者1、3、5年无瘤生存率,单纯肝尾状叶切除术组分别为25.9％、0％、0％,联合肝尾状叶切除术组为74.3％、46.7％、31.2％.两组恶性病变患者的总生存率分别为68.6％、19.7％、0％和100％、66.5％、41.8％.结论 肝尾状巨大肿瘤切除术的术式取决于病变的大小、位置及肝脏的功能储备.肝功能储备良好的病例,肝尾状叶切除联合其他部分肝切除是首选.而对于肝功能储备处于临者值的患者,惟一可行的术式是单纯的肝尾状叶切除术.     

肝尾状叶肿瘤切除术

肝尾状叶按Ｃｏｎｉｎａｕｄ分段为第Ⅰ肝段，尾状叶肿瘤相对肝左、右叶而言较少见。由于尾状叶的特殊解剖位置所限，致使切除尾状叶肿瘤在手术技术上具有相当的难度，术中还可能发生致命性并发症。随着对尾状叶解剖的深入了解和肝外科技术的不断提高，近年国内外累计报告...     

尾状叶肝癌的治疗进展

原发性肝癌(简称肝癌)是消化道常见肿瘤之一,手术切除仍是治疗肝癌首选并且最有效的方法.而位于肝尾状叶的肝癌,由于其位置深在,显露困难,局部解剖复杂,过去常被当作肝胆外科的“手术禁区”.近年来,随着尾状叶解剖的深入、影像学的发展、手术入路的不断探索、手术方式及其他辅助治疗方法的不断改善,尾状叶切除已不罕见.本文仅对肝尾状叶的局部解剖及尾状叶肝癌的相关治疗进展作一简要综述.     

单独肝尾状叶血管瘤切除术

Isolated resection of bemangioma in the cau-date lobe is challenging due to the surgical anatomy of caudate lobe. The caudate lobe consists three portions: Spiegel's lobe, paracaval portion and caudate process. Most of the blood supply of caudate lobe is provided by the posterior segmental branches of the portal vein and left hepatic artery. The hepatic venous drainage encompasses a few sizable and several small branches that join the inferior vena cava. Selection of the ideal route for bepatectomy, adequate mobilization of the liver, preparatory placement of band for hepatic vascular occlusion are key factors during the operation.     

Relation among portal segmentation, proper hepatic vein, and external notch of the caudate lobe in the human liver

OBJECTIVE: To identify portal segmentation and a portal fissure in the caudate lobe of the human liver in relation to the hepatic venous system and the external notch at the caudal edge of the caudate lobe. SUMMARY BACKGROUND DATA: Although the anatomy of the caudate lobe has been studied, the detailed anatomy has not yet been clarified; this is necessary to develop safe procedures for caudate lobe resection. METHODS: A total of 88 formalin-fixed human livers were dissected to visualize the portal vein and hepatic vein systems of the caudate lobe in relation to the external notch. RESULTS: The patterns of portal branching were classified into two types. In 58 livers (67.4%), the territories of the first-order portal branches were clearly divided into two areas (the Spiegel lobe and the paracaval portion). In the remaining 28 livers (32.6%), the territories of the second-order portal branches were clearly divided into two areas. These two areas were distinctly separated by an internal plane, which was coincident with the external notch. The caudate lobe had a systematized hepatic venous system that consisted of one (87.5%) or two (11.4%) proper hepatic veins and plural accessory hepatic veins. The proper hepatic veins laid along the internal plane between these two portal areas. CONCLUSION: The caudate lobe exhibited distinct portal segmentation with a portal fissure that was indicated internally by the proper hepatic vein and externally by the notch at the caudal edge of the caudate lobe.     

Preoperative cholangiography of the caudate lobe: Surgical anatomy and staging for biliary carcinoma

The biliary branches of the caudate lobe (B1) join the right hepatic duct, the left hepatic duct, the confluence of these ducts, and/or the right posterior segmental bile duct. Therefore, in the preoperative staging of biliary tract carcinoma it is important to delineate the anatomy of B1 and the extent of cancer spread into B1. Tube cholangiography through percutaneous transhepatic biliary drainage or selective cholangiography by percutaneous transhepatic cholangioscopy enables us to obtain fine images of B1. We have developed cholangiography in the cephalad anterior oblique position to visualize B1 more clearly and distinctly. Four separate types of biliary branches are identified in the caudate lobe: (1) A duct running from the cranial portion of the right caudate lobe along the inferior vena cava to the hepatic hilus (B1r); (2) a duct from the cranial portion of the left caudate lobe to the hepatic hilus (B1ls); (3) a duct from the left lateral part of the left caudate lobe to the hepatic hilus (B1li); and (4) a duct from the caudate process to the hepatic hilus (B1c). The findings of the root of B1 in resected patients with biliary tract carcinoma were classified into four groups: not stenotic, short segmental stenosis, long segmental stenosis, and poorly imaged. A study of 64 branches of B1 in 42 resected patients with biliary tract cancer revealed carcinoma invasion in or near the root of B1 in all patients with poorly imaged or long segmental stenosis of B1, and in 33% of those with short segmental stenosis of B1.
