新生儿泪囊炎泪道探通术风险性研究

Evaluation of the risk factors in probing of lacrimal passage for neonatal dacryocystitis

目的研究婴幼儿泪道探通术在治疗新生儿泪囊炎中的风险。方法对过去10年中施行的婴幼儿泪道探通术的术式、探通次数及探通时间进行回顾性分析，探讨以上因素与泪道探通术并发症发生率之间的关系。结果泪道探通2771例3163眼。治愈2715例3101眼，治愈率为98．04％，共出现假道及下泪点撕裂等并发症36例36眼，并发症总发生率1．14％。冲洗式探通者并发症发生率低于非冲洗式探通者，差异有统计学意义。探通1次并发症发生率低于探通2次者，差异有统计学意义。在6个月龄及以前实施探通者并发症发生率低于6个月以后者，差异有统计学意义。结论泪道探通术治疗新生儿泪囊炎虽有一定风险，但有较高治愈率，严格操作步骤可以避免或减少并发症的出现。

Objective To evaluate the risk facors in probing of lacrimal passage for neonatal dacryocystitis. Methods A retrospective study was done to analyze different operations, number of times and timing of operation in probing of lacrimal passage in the past ten years. The relationship between the fac- tors described above and the incidence of complications was discussed. Results In 3163 eyes of 2771 ca- ses, 3101 eyes of 2715 cases were cured, the success rate was 98.04%. There were 36 eyes of 36 cases complicated with false passage or laceration of inferior lacrimal puncture. The incidence of complication was 1.14%. The patients treated with probing by lacrimal duet flushing had a lower frequence of complication than the patients treated by probing without duct flushing. The difference was statistically significant. The in- cidences of complications with once probing were lower than those with twice probing. Compared with the pa- tients under six months of age, the patients more than six months had a higher complieatou rate. The differ- ence had a statistical significance. Conclusion Probing of lacrimal passsage has high success rate for neo- natal dacryocystitis. Strict operating procedures can avoid the risk factors and reduce or eliminate the compli- cation.
