方法：采用病例对照研究，回顾性分析2013-09/2014-10我院就诊的43例泪小管炎患者，病例组22例行泪道内窥镜联合泪小管切开，对照组21例行泪小管排石、泪小管内抗生素注射的保守治疗，随访1a观察二者的临床疗效并进行统计学比较。

结果：病例组中21例治愈，1例好转，未有无效患者，有效率100%。对照组中10例治愈，5例好转，6例无效行手术治疗，有效率71%。病例组较对照组能有效提高泪小管炎治疗的有效率，二者的差异有统计学意义(P<0.05)。

结论：泪道内窥镜联合泪小管切开治疗泪小管炎微创、安全、有效。

METHODS: A case-control study.Forty-three patients with canaliculitis were collected from September 2013 to October 2014 in our hospital. The patients were divided into case group with lacrimal endoscope with canalicular incision for 22 cases, and control group with canalicular concretion extruded and antibiotic injection within lacrimal canaliculi for 21 cases. The patients' 1a follow-up was carried out to observe the clinical effect of these two groups and to conduct statistical analysis.

RESULTS:The effective rate was 100% with 21 patients cured, one patient improved and no treatment failure for case group. The value was 71% with 10 patients cured, 5 patients improved and 6 treatment failure(surgical treatment)for control group. It had a better effective rate for canaliculitis treatment in case group, compared to control group. The difference was statistically significant(P<0.05).

CONCLUSION:The treatment of lacrimal endoscope with canalicular incision was minimally invasive, safe and effective for canaliculitis.
