摘要

目的:评估超微型内窥镜系统对离体猪肝肝内细小胆管（直径<1 mm）成像的可行性

并探讨其临床价值。方法:取新鲜离体猪肝10具

在实时图像监测下

经肝胆总管处缓慢地插入超微型光纤（外径=0.8 mm）

逐级观察肝叶、肝段胆道结构、黏膜形态并记录图像

直到不能再进入

固定光纤后行胆道CT三维重建

获得超微型光纤到达最小胆管直径数据。结果:超微型内窥镜系统可清晰显示猪远端肝内细小胆管

CT三维重建证实超微型内窥镜系统能观察到直径<1 mm的肝内细小胆管。结论:超微型内窥镜系统对远端肝内细小胆管成像可行

在肝内细胆道疾病方面诊治方面有潜在价值。

Abstract

Objective:To investigate the feasibility and clinical application value of imaging swine intrahepatic bile ducts(diameter <1mm)with an experiment Ultrathin Endoscope System in vitro. Methods:In vitro ten swine livers were scoped with a micro-imaging fiber(outer diameter =0.8 mm). Images of bile ducts at various levels and mucosal color were observed. The operation was stopped once it was difficult to insert ahead. Three-dimensional reconstruction was performed simultaneously to show the diameter of the distal bile ducts. Results:Perfect images of distal intrahepatic bile ducts were obtained. The CT(Computer Tomography)images showed that the micro-imaging fiber was able to access the distal bile ducts(diameter <1 mm). Conclusion:The micro-imaging fiber can probe into small intrahepatic bile ducts(diameter <1 mm). Ultrathin Endoscope System may have potential practical value in diagnosing the disease of intrahepatic bile ducts.
