目的:探讨短单反“α”法用于内镜下鼻胆管引流术后鼻胆管的固定效果。方法:选取2019年1—10月在同济大学附属东方医院实施内镜下鼻胆管引流术679例，按随机数字表法分为试验组（短单反“α”法）155例和对照组137例（常规反“α”法），进行鼻胆管固定，比较2组患者鼻胆管固定时间、脱出率、护理时间、舒适度及胆汁引流量。结果:试验组平均鼻胆管固定时间为（18.31 ± 1.67）s，脱出率5.2%（8/155），护理时间为（35.03 ± 2.68）s，均低于对照组的（46.50 ± 5.50）s，13.9%（19/137）和（72.07 ± 7.63）s，差异均有统计学意义（n t/n χ2值为60.795、6.570、56.629，n P<0.01或0.05）；试验组舒适度评分为（4.61 ± 1.06）分，胆汁引流量（241.52 ± 53.95）ml/d，优于对照组的（5.76 ± 0.76）分和（174.09 ± 47.55）ml/d，差异均有统计学意义（n t值为10.448、11.265，n P<0.01）。n 结论:采取短单反“α”法固定鼻胆管具有操作及护理简单、脱出率低、舒适度高、引流效果好的优点，值得临床推广。“,”Objective:To investigate the effect of short single reverse-α fixation of nasobiliary tube after endoscopic nasobiliary drainage.Methods:From January 2019 to October 2019, the patients who performed with endoscopic nasolbiliary drainage in Tongji University Affiliated Shanghai East Hospital were randomly divided into experimental group (short single reverse-α fixation, 155 cases) and control group (routine reverse-α fixation, 137 cases). The incidences of the fixation time, prolapse rate, nursing time, scores of nasal comfort and bile flow rate of nasobiliary duct were evaluated between the two groups.Results:The average time of nasobiliary duct fixation was (18.31±1.67) s, the prolapse rate was 5.2% (8/155) and the time of nursing was (35.03±2.68) s, which were lower than those of the control group (46.50±5.50) s, 13.9% (19/137) and (72.07±7.63) s. The difference was statistically significant (n t or n χn 2 values were 60.795, 6.570, 56.629, n P<0.01 or 0.05). The comfort score of the experimental group was (4.61±1.06) points, the bile flow rate was (241.52±53.95) ml/days, which were higher than (5.76±0.76) points and (174.09±47.55) ml/days of the control group, the difference was statistically significant (n t values were 10.448, 11.265, n P<0.01).n Conclusions:Shortening the length of nasobiliary duct combined with single reaction “α” method has the advantages of simper operation and nursing, low prolapse rate, high comfort and good drainage effect. It is worthy of clinical application.
