目的:分析婴儿先天性鼻泪管阻塞泪道探通术并发症发生的原因和治疗。方法:回顾性分析东莞市寮步医院2009年至2018年的先天性鼻泪管阻塞患儿(1～11个月龄)，行泪道探通手术后发生并发症者124眼的临床资料。结果:本研究共772眼泪道探通术中12眼(1.55%)发生假道，112眼(14.51%)发生泪点出血。并发症发生率随月龄增加而增加，3月龄以下患儿无出血发生。操作者熟练程度与假道的发生有关(n χ2＝12.00，n P＝0.001)，与出血的发生无关(n χ2＝0.562，n P＝0.453)，探通并发症与感染无关(n P>0.05)。n 结论:先天性鼻泪管阻塞患儿，在2～3个月龄时行泪道探通手术并发症少，规范操作、技术熟练，可有效减少并发症的发生。“,”Objective:To analyze the causes and the clinical preventive measures of the complications of lacrimal duct probing for obstruction of nasolacrimal duct of infants.Methods:The clinical data of 124 eyes with complications after infants, aged 1-11 months, with congenital nasolacrimal duct obstructions who underwent lacrimal duct probing from 2009 to 2018 in Liaobu Hospital of Dongguan were retrospectively analyzed.Results:There were 12 eyes (1.55%) with false passage and 112 eyes (14.51%) with lacrimal punctum hemorrhage among 772 eyes with lacrimal duct probing. The incidence of complications increased with the increase of month age, and no bleeding occurred in infants below 3 months. Operator proficiency was related to the occurrence of false passage (n χ2=12.000, n P=0.001), but not related to the occurrence of bleeding(n χ2=0.562, n P=0.453). Probe complications were not related to infection (n P>0.05).n Conclusion:The complications after lacrimal duct probing in infants with congenital nasolacrimal duct obstruction aged 2-3 months is less.Standardized operation and skilled technique can effectively reduce the incidence of complications.
