目的：了解先天性泪囊炎行泪道探通术的临床疗效。

方法：选取2011-01/2016-12于我院就诊的先天性泪囊炎患儿322例361眼作为研究对象，患儿均行泪道探通术。术后1wk，1、3mo复诊观察疗效。

结果：先天性泪囊炎患儿322例361眼治愈率为99.2%(358眼)，3眼鼻泪管为板块样骨性阻塞； 1眼发生皮下水肿，11眼泪小点出血，其他无明显并发症发生； 8～18月龄患儿一次性探通成功率85.0%(204/240)，显著高于>18月龄患儿一次性探通率60.2%(71/118)，差异有统计学意义(χ²=27.387，P<0.05)； 泪道多处阻塞或粘连一次性探通率4.4%(3/68)显著低于泪道下端膜性阻塞探通率94.1%(273/290)，差异有统计学意义(χ²=251.134，P<0.05)。

结论：泪道探通术治疗先天性泪囊炎疗效显著，有效解除患儿泪囊炎症状，其手术操作简单，安全可靠，但其治疗疗效与泪道阻塞性质有密切关系。

METHODS: Totally 322 children(361 eyes)with congenital dacryocystitis treated in our hospital from January 2011 to December 2016 were selected and underwent lacrimal duct probing. The follow-up were taken on 1wk, 1 and 3mo after operation.

RESULTS: The cure rate of 322 cases(361 eyes)of congenital dacryocystitis was 99.2%(358 eyes); 3 eyes had nasolacrimal duct bony obstruction, 1 eyes had edema, 11 eyes had bleeding, and no other complications occurred. The success rate of once probing of children between 9 months to 18 months(85.0%, 204 eyes/240 eyes)was significantly higher than that of children older than 18 months(60.2%, 71 eyes/118 eyes), the difference was statistically significant(χ²=27.387, P<0.05). The one-time probing rate of multiple obstruction or adhesion of lacrimal duct was 4.4%(3 eyes/68 eyes), which was significantly lower than 94.1% of membranous obstruction at the lower end of lacrimal passage(273 eyes/290 eyes), the difference was statistically significant(χ²=251.134, P<0.05).

CONCLUSION: Lacrimal duct probing can be used for most congenital dacryocystitis and can relieve the symptoms of dacryocystitis effectively. The operation is simple, safe and reliable, but the therapeutic effect is closely related to the type of lacrimal passage obstruction.
