Purpose

To identify the efficacy and adverse event rates of balloon dacryoplasty in cases of congenital nasolacrimal duct obstruction in children who fail to respond to an initial nasolacrimal duct probing.

Methods

A literature search was last performed in September 2017 in the PubMed database to identify all reports of balloon dacryoplasty. All searches up to and including the last search were limited to the English language, and they yielded 104 articles that were assessed for relevancy. Thirty-six articles were selected for full review, and 8 of these were selected for inclusion in this assessment and assigned a quality of evidence rating by the panel methodologist.

Results

Three of the 8 studies included in this assessment were rated level II, and 5 were rated level III. Success rates varied from 75% to 100%. Only 2 complications were identified, and these were cases of self-limited postoperative emesis. The 2 studies that compared balloon dacryoplasty with lacrimal stenting reported that outcomes were comparable between the 2 techniques.

Conclusions

Although level I evidence was not available, the studies that were uncovered in the literature review indicate that balloon dacryoplasty is a safe, effective procedure to address congenital nasolacrimal duct obstruction that persists after standard probings. The outcomes of this intervention are similar to those of lacrimal stenting, and the absence of an implanted stent theoretically reduces the risk of complications.

先天性鼻泪管阻塞的球囊泪成形术

目的

为了确定先天性鼻泪管阻塞的儿童对初始鼻泪管探测没有反应的情况，球囊泪成形术的疗效和不良事件发生率。

方法

文献检索最后一次于2017年9月在PubMed数据库中进行，以鉴定所有球囊泪成形术的报告。直到最后一次搜索（包括最后一次搜索），所有搜索都限于英语，并且他们得出104篇文章的相关性得到了评估。选择了36篇文章进行全面审查，并选择了其中8篇纳入本评估，并由专家组方法学家对证据质量进行了评级。

结果

评估中包括的8项研究中有3项被评为II级，5项被评为III级。成功率从75％到100％不等。仅发现了2种并发症，这些都是术后自我限制的呕吐病例。两项将球囊泪成形术与泪道支架置入术进行比较的研究报告说，两种技术之间的结果相当。

结论

尽管尚无I级证据，但文献综述中未发现的研究表明，球囊泪成形术是一种解决先天性鼻泪管阻塞的安全，有效的方法，该阻塞在标准探测后仍然存在。这种干预的结果类似于泪道支架置入的结果，并且理论上无需植入支架可降低发生并发症的风险。
