目的探讨新型泪道探通针泪道探通后逆行置管的临床效果。方法收集我院2012年6月至2013年10月在我院确诊为泪道疾病需行逆行置管治疗的门诊患者106例（133只眼），doll’s随机数字法分为观察组53例（68只眼）和对照组53例（65只眼）。对照组采用传统钢针进行泪道探通，观察组采用新型泪道探通针探通，而后进行逆行置管。观察两组治疗有效率，置管成功率，自行脱管率，并发症发生情况。结果两组置管成功率及并发症（鼻腔出血、下睑肿胀）比较， P ＜0．05，差异具有统计学意义；术后6个月内两组置管自行脱落人数经统计学分析，P ＜0．05，差异具有统计学意义；术中观察组因痛疼需追加麻醉者2例，对照组9例，经比较，P ＜0．05，差异具有统计学意义。两组治疗有效率情况经Ridit 分析发现，观察组稍优于对照组（观察组＜对照组），两组R 的95％置信区间均不包含0．5，差异具有统计学意义。结论新型泪道探通针泪道探通及鼻泪管义管置管术，价廉，操作简单，术中损伤小，患者更易接受，值得推广。%Objective To investigate the clinical effect of retrograde catheterization after probing of lacrimal pas-sage with a new type probing needle. Methods Author enrolled 106 patients (133 eyes)who were diagnosed with lacri-mal duct diseases and needed the retrograde catheterization in our hospital from June 2012 to October 2013. Patients were divided into two groups randomly. Fifty-three patients (68 eyes)received lacrimal passage probing with a new type of probe,and the other 53 patients (65 eyes)served as control by probing with a traditional needle. After probing,all pa-tients underwent retrograde catheterization. We observed the treatment efficiency,success rate of catheterization,rate of self-decannulation and the complications. Results There were significant differences in success rate of catheterization and the complications (nasal bleeding,lower eyelid swelling)between two groups (P < 0. 05). Rate of self-decannulation at 6 month was significantly different (P < 0. 05). There were 2 patients needed additional anesthesia in observation group, and 9 patients needed additional anesthesia in control group (P < 0. 05). The effective rate was slightly better in patients received probing with a new type of probe,revealed by using Ridit analysis,but this difference was not significant. Con-clusion The new type lacrimal passage probing is an inexpensive,simple,and safe treatment. Patients are more likely to accept it.
