经泪小点泪管内镜操作技巧及治疗泪管阻塞疗效分析

Handling skill of endoscopy of lacrimal drainage system and its treatment for lacrimal passage obstruction

目的探讨经泪小点泪管内镜治疗泪管阻塞的手术方法及疗效。方法121例(142眼)泪管阻塞患者于局部麻醉下使用经泪小点泪管内镜进行泪管检查,对阻塞部位进行激光或微型电钻处理,术后随访6个月观察疗效。结果术中检查成功率及再通率为100%,术后随访治愈114眼(80.28%)。其中上泪管阻塞、鼻泪管阻塞、上泪管并鼻泪管阻塞及慢性泪囊炎治愈率分别为80.36%、84.91%、57.14%及76.92%。结论经泪小点泪管内镜能对泪管阻塞性疾病进行有效观察及针对性治疗。

[Objective] To evaluate the treatment of the lacrimal passage obstructions with endoscopy of lacrimal drainage system and investigate its handling skill. [Methods] 121 patients （142 eyes） with lacrimal passage obstructions were examined by endoscopy of the lacrimal drainage system after local anesthesia, and the obstructions were treated with laser or micro-drill. Ointment with 0.3% tobramycin and 0.1% dexamethasone was injected into the lacrimal passage after unblocked irrigation. All the patients were followed up after operation for 6 months. [Restilts] The scene in lacrimal passage of each patient could be observed effectively. All of the obstructions could be cleaned out in the operation.The follow up showed that 114 eyes （80.28%） were cured by the treatment. The cure rate of presaccal canalicular obstruction, nasolacrimal duct obstruction, obstruction of the two segments, and chronic dacryocystitis were 80.36%, 84.91%, 57.14% and 76.92%, respectively. [Conclusion] The lacrimal passage obstructions can be observed directly and treated with endoscopy of the lacrimal drainage system. It is an effective way to treat such diseases.
