ABSTRACT Objective To discuss the importance of the study of conformation and variation of extrahepatic bile duct before gallbladder operationMethods The images of 100 cases having normal structure of gallbladder and extrahepatic bile duct were studied;the conformations and confluence sites were analyzedResults Among the 100 cases,97 cases had clear images of extrahepatic bile duct (97%),3 cases with large amount of air bulbs in bile duct because of the laxation of the lower common bile duct still had clear images of the general conformation of extrahepatic bile duct,87 cases had clear images of gallbladder and cystic duct (87%),13 cases (13%) had partial images of gallbladder or cystic ductConclusions ERCP can clearly show out the conformation and variation of extrahepatic bile duct and cystic duct and it is of important value before gallbladder operation

目的 通过对100例胆囊及肝外胆管正常结构尚存在的患者ERCP图像资料进行归纳和分析，探讨胆囊手术术前了解肝外胆道系统形态及变异的重要性。方法选出100例胆囊及肝外胆管正常结构尚存在的患者图像，对其形态、汇合位置进行分析。结果 100例患者图像中肝外胆管显示清晰者97例(97%)，3例因胆总管下端开口松弛导致大量气泡进入胆道，但肝外胆管大体形态显示尚清晰，胆囊及胆囊管显示清晰者87例(87%)，13例(13%)仅部分显示胆囊或胆囊管。结论 ERCP可以清晰显示肝外胆管及胆囊管的形态及变异情况，对于胆囊手术术前了解肝外胆道系统形态及变异有重要价值。 ERCP；胆囊管；肝外胆管

This study experimentally examined the heat transfer characteristics of 180-deg turning duct under forced convection cooling, as the internal cooling structure of 180-deg turning duct is widely applied to industrial cooling. While several perforated holes were separately arranged within the 180-deg turning duct, the cold flow of better cooling capability was guided in the first duct into the second duct in advance, so as to reduce the overheating of the second duct and realize uniform cooling of the machine members. In addition, the centrally separated holes could yield extra turbulence against the air current, and the interaction between bypass air current and mainstream may possibly improve the overall heat transfer capability.

本研究系以实验方法探讨180度转弯通道於强制对流冷却下之热传递特性，180度转弯通道之内部冷却构型在工业冷却之应用非常广泛，本研究设计将180度转弯通道其中间分隔具多个穿孔，目的在将第一流道内具较佳冷却能力之冷流提早引入第二流道，以减少第二流道产生过热情况，如此可使得机件获得均匀之冷却，此外，中间分隔上之穿孔对气流也具有额外之扰动效果、流经穿孔之旁通气流与主流交互作用，这都有可能增益整体热传能力。

To prevent cholelith in residual gallbladder, it is important to choose the proper timing and mode of cholecystectomy, to anatomize cystic duct, common hepatic duct, common duct clearly and cut cystic duct 0.3~0.5cm apart from common duct.

合理掌握胆囊切除术的手术时机、和术式，在术中解剖清楚胆囊管、肝总管、胆总管三管关系，然后距胆总管0.3~0.5cm切断结扎胆囊管，是预防残余胆囊结石的关键。

Results: NGF and TrkA were mainly distributed in intercalated duct, striated duct, excretory duct cells in salivary gland tissues around neoplasm, proven by pale brown positive response in cell membrane and plasm. p75 was not only found in duct epithelial cells in salivary gland tissues around neoplasm, but also apparently in serous acinus plasm.

研究发现：肿瘤周围涎腺组织中，NGF和TrkA主要分布于闰管、纹管及排泄管细胞，表现为胞膜及胞浆呈棕黄色阳性反应。p75在肿瘤周围涎腺组织中，不仅分布于导管上皮细胞，浆液性腺泡胞浆亦呈明显的阳性反应。

The duct is diffusingly narrow. The bile duct wall is stiff without flexibility, taking the shape of leaden tube. The normal intrahepatic bile duct is deprived of its "willow"-style softness and smoothness. The intrahepatic bile duct branches are to scarce to reach the edge of the liver, taking the shape of "withered arborization" or "pruned trees".

Ultrasound,ERCP,MRCP,liver enzyme profile and reoperation confirmed the folowing: Extra-hepatic bile duct or the right hepatic duct was ligated in 9 cases,common bile duct residual stone in 6,partial gallbladder or gallbladder duct stone in 4,biliary leak in 4, cholangitic hepatitis in 4,hepatitis B or posthepatitis cirrhosis in 5,icterus after blood transfusion in 2,hemobilia in 2, ligation of right branch of hepatic artery in 2, and icterus of unknown causes in 5 cases.
