梁力建教授有不少作者提出胆管癌的分型,大多数的分型包括了肝外胆管的各部,如Nakeeb(1996)把肝外胆管瘤分为肝内型、肝门周围型、末段型,其中肝门周围型包括了肝门部、肝总管和胰腺上缘以上的胆管瘤。而Pitt(199)把胆管癌分为9型,其中属于肝门部胆管癌的有Ill型(右肝管)、IV型(左肝管)、V型(左右肝管汇合部)、对型(肝总管)。1975年Bismuth-COrlette将肝门部胆管瘤分为4型:l型,肿瘤位于肝总管,未侵犯汇合部;0型,肿瘤波及汇合部,未侵犯左右肝管;m型,已侵犯右肝管(Illa)或侵犯左肝管(Illb);IV型,已侵犯…  相似文献

提问与解答     
关于Ⅳ型胆管癌:本组中75例,大多数(48例)可行半肝加尾状叶切除治疗。一般认为已无手术切除可能,除非行肝移植。因为均累及肝内左右肝管或汇合部(左内外及右前后胆管),如1例累及肝内肝管汇合部.另1例仅累及左或右肝管开口处是否划入Ⅳ型?  相似文献

切开肝内胆管治疗复杂肝内胆管结石的手术入路和方法   总被引:1,自引:0,他引:1  
目的 探讨显露和剖开肝内各叶、段胆管的手术方法,提高复杂性肝内胆管结石病的治疗效果。方法 从肝内胆管手术显露的角度,研究了30个成人肝脏标本肝内各叶、段胆管与血管走行位置的解剖关系,设计了新的手术方法、用于治疗复杂性肝内胆管结石46例。结果 肝内胆管与血管走行的位置关系。从肝脏的脏面观:左右肝管均位于门静脉左右干的前上缘。左内叶胆管、右前叶胆管位于相应门静脉支的前内侧(近肝门侧)。右后叶胆管有73.3%(22/30)位于门静脉右前支(18/30)或门静脉右前下段支(4/30)脏面深侧;80%(24/30)走行于门静脉右后叶支脏面深侧(20/30)或后上缘(4/30)。左外叶胆管基本上都走行于门静脉矢状部脏面深侧,只有2个标本的左外叶下段支胆管在其浅侧。肝动脉在肝内各叶段的分支基本上走行与Glisson鞘内胆管与门静脉之间或侧旁。从肝脏膈面观:肝内各叶、段胆管与血管的解剖位置关系大致与脏面观相反或接近相反。据此,从肝脏脏面显露肝门、可以连续切开左右肝管和多数左内叶及右前叶胆管,但难以显露右后叶及右叶各段胆管和左外叶胆管;而从肝脏膈面进路切开肝方叶或肝中裂、再沿右后叶胆管投影方向切开肝实质,则可避开右肝内的门静脉主要分支,比较容易显露和切开右肝内各叶、段胆管汇合部及狭窄段。从肝左叶膈面切开左外叶胆管,可避免损伤左门静脉矢状况。设计经肝的脏面显露和剖开肝门及左右肝管与经肝的膈面显露和剖开肝内叶、段胆管相结合的手术方法,治疗复杂性肝内多叶、多段胆管多发结石并胆管狭窄的病人46例。无手术死亡。31例平均随访39个月,效果优良28例(90%),好转2例(6.5%),无效1例(3.5%)。结论 经肝的脏面和膈面相结合的手术入路,显露和剖开肝内外胆管及其狭窄段,便于取出结石。将剖开的肝内外胆管与空肠Roux-en-y大口吻合,则可解除胆道狭窄,建立通畅的胆流通道,是治疗复杂性肝内胆管结石有效的手术方法。  相似文献

15 patients are reviewed who had stenosis or obstruction at the hilus of the bile duct. Percutaneous transhepatic or endoscopic transduodenal cholangiography is indispensable for establishing the diagnosis before operation. Primary carcinomas involving the junction of the hepatic ducts may be regarded as resectable if proximal extension of the tumor is limited to below the second bifurcation of the intrahepatic bile ducts in both the right and left lobes and if the proper hepatic artery and portal vein are still free from tumor invasion. Our favourable operation procedures for resection or palliative decompression of the biliary tree are discussed.  相似文献

We have studied the surgical anatomy of the intrahepatic bile duct, hepatic hilus, and caudate lobe based on intraoperative findings and selective cholangiography of surgical patients and resected specimens, and have established the cholangiographic anatomy of the intrahepatic subsegmental bile duct. Thorough knowledge of the three-dimensional anatomy of the subsegmental bile duct, hepatic hilus, and caudate lobe is indispensable for curative surgery of hilar cholangiocarcinoma. We designed and actually performed 15 kinds of hepatic segmentectomies with caudate lobectomy and extrahepatic bile buct resection in 100 consecutive patients, with curative resection being possible in 82 patients. Postoperative survival after curative resection of hilar cholangiocarcinoma was better than expected, and the 5-year survival rates for all 82 patients with curative resection and for 55 patients with curative surgery without portal vein resection were 31% and 43%, respectively. Hepatic segmentectomy with caudate lobectomy and extrahepatic bile duct resection should be designed not only in accordance with the preoperative diagnosis of tumor extension into the intrahepatic bile ducts but also so that curative surgery for advanced hilar cholangiocarcinoma can be performed.  相似文献

OBJECTIVE: To evaluate anatomic variations of the biliary tree as applied to living donor liver transplantation. SUMMARY BACKGROUND DATA: Anatomic variability is the rule rather than the exception in liver surgery. However, few studies have focused on the anatomic variations of the biliary tree in living donor liver transplantation in relation to biliary reconstruction. METHODS: From November 1992 to June 2002, 165 patients underwent major hepatectomy with extrahepatic bile duct resection; right-sided hepatectomy in 110 patients and left-sided hepatectomy in 55. Confluence patterns of the intrahepatic bile ducts at the hepatic hilum in the surgical specimens were studied. RESULTS: Confluence patterns of the right intrahepatic bile ducts were classified into 7 types. The right hepatic duct was absent in 4 of the 7 types and in 29 (26%) of the 110 livers. Confluence patterns of the left intrahepatic bile ducts were classified into 4 types. The left hepatic duct was absent in 1 of the 4 types and in 1 (2%) of the 55 livers. CONCLUSIONS: In harvesting the right liver from a donor without a right hepatic duct, 2 or more bile duct stumps will be present in the plane of transection in the graft in 3 patterns based on their relation to the portal vein. Accurate knowledge of the variations in the hepatic confluence is essential for successful living donor liver transplantation.  相似文献

对于肝胆管结石的治疗目前已取得了很多成功的经验,但最常使用的胆肠吻合术虽经不断改进,仍未能从根本上解决返流性胆管炎、胃肠分泌功能紊乱等并发症。为此,设计了一种新术式:即皮下通道型胆囊肝胆管成形术。在清除结石,解除肝内外胆管狭窄、肝门整形的基础上,利用胆囊壶腹部切开相应大小的切口与之吻合,并适当游离胆囊,使其底部可以被固定到切口皮下。患者必须具备基本正常的胆囊、肝外胆管和Oddi括约肌。同时要求术中基本取尽肝内结石或切除病灶。已完成此手术共35例,所有患者手术顺利,术后未发现并发症。其中1例3年后结石复发,1例2年后发生胆道蛔虫,均经皮下胆囊通道用胆道镜轻易取出。该术式既能处理好结石和狭窄问题,又能保存胆囊、胆管、Oddi括约肌的功能,保持胃肠道的正常生理通路,并能以最简捷的方法处理术后结石复发和胆道内其它问题  相似文献

Fibrillin-1, one of the main constituents of microfibrils, is present in normal adult liver and overexpressed in fibrotic area around cirrhotic nodules and hepatocellular carcinoma. In this work fibrillin-1 expression was studied by immunohistochemistry in liver samples from children with various cholestatic diseases corresponding to paucity of intrahepatic bile ducts, biliary atresia, congenital hepatic fibrosis, Byler's disease, mitochondrial cytopathy, sclerosing cholangitis, or choledochal cyst. As controls, histologically normal liver samples were used. In control liver, as in adult, fibrillin-1 was expressed in vessel walls, sinusoids, and portal connective tissue, particularly at the interface with the limiting hepatocytic plate and close to the basement membrane of bile ducts. In paucity of intrahepatic bile ducts without fibrosis, the fibrillin-1 distribution was similar to controls. In cholestatic diseases associated with severe fibrosis, such as biliary atresia, congenital hepatic fibrosis, Byler's disease, mitochondrial cytopathy, or sclerosing cholangitis, an enhanced deposition of fibrillin-1 was observed in portal connective tissue and fibrous septa. The strong fibrillin-1 expression close to the basement membrane of biliary structures was lost in cholestatic diseases, except biliary atresia. Finally, in normal and pathologic tissues, fibrillin-1 was co-localized with its putative receptor alphaVbeta3 in sinusoids but not around biliary structures.  相似文献

BACKGROUND/PURPOSE: In biliary atresia (BA), although the intrahepatic bile ducts are reported to appear in the fetal configuration in about 20% to 60% of cases, information about the 3-dimensional (3-D) morphology of the hilar biliary structures is limited. The authors, therefore, have applied the technique of computer-generated 3-D reconstruction, to study the morphology of the hilar biliary structures in patients who have undergone biliary decompression. METHODS: Computer-generated 3-D reconstructions were performed from serial sections of the hepatic hilum of 4 BA patients and compared with those obtained from a 3-day old infant who had no apparent biliary disease but died of congenital diaphragmatic hernia (CDH) and with normal human fetal ductal plate at 11 weeks of gestation. RESULTS: In all 4 BA patients, the hilar bile ducts strongly resembled the ductal plate structures of the fetus rather than the bile ducts of the CDH infant. This leads the authors to suggest that these abnormal biliary structures are the result of improper ductal plate remodeling at the hepatic hilum. In 3 of the BA patients there were some tubular bile ducts that probably are the result of delayed and abnormal attempt at ductal plate remodeling.  相似文献

Resected hepatic tissues of 24 patients with primary intrahepatic lithiasis were examined histo-pathologically. Calcium bilirubinate stones, cellular debris and mucinous substances occupied the lumen of large dilated intrahepatic bile ducts. Numerous mucin secreting glands were seen within or around the wall of these bile ducts. Similar structures were demonstrated in two patients with non calculous congenital dilatation of the intrahepatic bile ducts. Cholestasis was often absent in the hepatic parenchyma. Production of intrahepatic gallstones may be caused by not only biliary stasis and infection, but also by intraductal mucin and slow flowing bile in combination with cellular debris, bile pigment and other bile components.
