巴马猪胆道盐酸消融实验 杨爱军1ab，董家鸿2（1.第三军医大学：a.基础部外科应用解剖与手术学教研室；b.西南医院肝胆外科，重庆 400038；2.中国人民解放军总医院肝胆外科，北京 100853） 提要：目的 研究以5%盐酸为消融剂，氰基丙烯酸酯为栓塞剂对巴马猪行选择性胆道消融栓塞后靶肝叶病理改变以及肝功改变，为临床应用胆道消融栓塞治疗肝内胆管结石提供实验依据。 方法 5头巴马猪左外叶胆道置管，造影后行选择性左外叶胆道消融并栓塞术，了解术后动物的肝脏功能状态、组织病理改变和术后存活情况。 结果 术后3天，肝功能与术前有显著差异。术后1周肝功能与术前无明显差异。术后1月，所有动物靶肝叶胶原增生明显，萎缩纤维化。 结论 5%盐酸是巴马猪有效的胆道消融剂。 关键词： 肝内胆管结石；消融；盐酸；巴马猪 中图法分类号 R575.62 文献标识码：A EXPEREMENT OF SELECTIVE BILE DUCT ABLATION WITH HYDORCHLORIC ACID IN BAMA SWINES YANG Ai-jun, DONG Jia-hong (Department of Hepatobiliary Surgery, Southwest Hospital, Third Military Medical University, Chongqing 400038, China) Abstract: Objective To study pathological changes after ablation with hydrochloric acid in intrahepatic bile ducts in Bama swines. Methods 5% hydrochloric acid was used as ablation reagent. The pathologic changes and liver function were evaluated after selective bile duct ablation. The hepatic histopathology and the survival rate of the Bama swines were observed. Results The index of liver function enzymes increased quickly during the first several days and decreased to normal levels on day 7 postoperation. Pathological analysis suggested hepatic cell death , bile duct fibrosis, inflammation cells infiltration and fibroblast proliferation. Liver atrophy and fibrosis were obvious on week 4. Masson stain suggested collagen increased remarkably 4 weeks after ablation (P0.05). Conclusions 5% is the proper concentration of hydrochloric acid for selective bile duct ablation in Bama swines.
