书·论著·梗阻性黄疸选择性胆管外引流大鼠模型的建立曾永毅张玉君郑树国董家鸿【摘要】目的建立梗阻性黄疸选择性胆管外引流(约占30%肝脏体积)动物模型,了解其对胆汁分泌及肝功能改善的影响,为肝门部胆管癌减黄实验及临床研究提供参考。方法采用结扎切断SD大鼠左中叶肝胆管及胆总管预制外引流管10d的方法,制作大鼠选择性胆管外引流模型,在引流的0、1、4、7、10、14d收集胆汁及检测肝功。结果成功建立了大鼠完全梗阻性黄疸部分肝脏外引流的模型并观测到其对胆汁分泌及肝功能改善的影响。结论与梗阻性黄疸全肝外引流模型相比,梗阻性黄疸约30%肝脏外引流能够改善肝功能,而且可以增加预保留肝的功能代偿。【关键词】胆管肿瘤;肝门部;梗阻性黄疸;大鼠【中图法分类号】R735.8【文献标识码】AEstablishmentofmodelofselectiveexternalbiliarydrainageinratswithobstructivejaundiceZENGYongyi,ZHANGYujun,ZHENGShuguo,DONGJiahong.SouthwestHospital&InstituteofHepatobiliarySurgery,ThirdMilitaryMedicalUniversity,Chongqing400038,China【Abstract】ObjectiveToestablishthemodelofselectiveexternalbiliarydrainageinratswithobstructivejaundicetounderstanditseffectsonbilesecretionandhepaticfunctionimprovementsoastoprovidesomereferenceforexperimentalandclinicalresearchesonhilarcholangiocarcinoma.MethodsWeemployeddoubleligationofthecommonbileductandtheleftandmiddlelobebileductandresetprefabricatedexternaldrainageductincommonbileductfor10daystomakethemodelofselectiveexternalbiliarydrainageinobstructivejaundicerats.Bilewascollectedandhepaticfunctioncheckedafterdrainagefor0,1,4,7,10,14days.ResultsWesuccessfullyestablishedthemodelofselectiveexternalbiliarydrainageinratswithobstructivejaundiceandfoundimprovementofbilesecretionandhepaticfunction.ConclusionComparedwithtotalexternalbiliarydrainageinratswithobstructionjaundice,selectiveexternalbiliarydrainagecannotonlyimprovehepaticfunction,butalsoimprovefunctionalcompensationoftheremnantliver.【Keywords】Biliarytumor;Hepaticportal;Obstructionjaundice;Rats肝门部胆管癌90%以上合并有不同程度的梗阻性黄疸,且大部分为完全梗阻性黄疸,术前多采取经皮经肝胆管引流(percutaneoustranshepaticbiliarydrainage,PTBD),以降低胆红素水平。肝门部胆管癌与其他引起梗黄的...
