DSA下导丝引出法在困难性鼻胆管口鼻转换中的临床研究

Clinical study of DSA guided wire extraction method in difficult nasobiliary duct oronasal conversion

目的评价数字减影血管造影(DSA)下导丝引出法在困难性鼻胆管口鼻转换中的应用效果。方法选择2018年8月-2019年3月同济大学附属东方医院困难性鼻胆管口鼻转换的患者46例,采用DSA下导丝引出法进行鼻胆管口鼻转换,观察该方法在困难性鼻胆管口鼻转换中的总成功率、一次成功率、导丝置入次数、平均操作时间、患者对刺激的反应程度评分及并发症发生率。结果总成功率100.00%(46/46),一次成功率100.00%(46/46),导丝置入(1.33±0.60)次,平均操作时间(37.72±14.04)s,刺激程度评分(1.43±0.69)分;其中,轻度刺激31例、中度刺激10例、重度刺激5例,不良反应发生率15.22%(7/46)。结论DSA下导丝引出法是解决困难性鼻胆管口鼻转换的一种安全、可行的方法。

Objective To investigate the effect of DSA guided wire extraction method in difficult nasobiliary duct oronasal conversion.Methods From August 2018 to March 2019,46 patients performed with difficult nasobiliary duct oronasal conversion were randomly studied.The patients were performed with the method of DSA guided wire extraction.The total success rate,one-time success rate,the average taking number,the average operation time,the number of wire placement,the degree of response to stimuli and the incidence of complications were researched.Results The total success rate was 100.00%(46/46)and one-time success rate was 100.00%(46/46).The average number of wire placement was(1.33±0.60),the average operation time was(37.72±14.04)s,the stimulation degree score was(1.43±0.69)including 31 cases of mild stimulation,10 cases of moderate stimulation and 5 cases of severe stimulation.The rate of adverse reaction was 15.22%(7/4).Conclusion The DSA guided wire extraction is a safe and feasible method for the patients with difficult nasobiliary ductoronasal conversion.
