Study on affect factors of laser plastic operation of lacrimal duct

【Abstract】 Objective To study the effect and the affect factors of laser plastic operation of lacrimal duct treating obstructive diseases of lacrimal duct.Methods results of laser plastic operation of lacrimal duct in treatment of obstructive diseases of lacrimal duct in our hospital by retrospective research were summarized;and the factors such as age'sex'progress'portion of obstruction'having or not purulent discharge andspecialmanagement in or after operation were observed.Results The cure-improve rate of laser plastic operation of lacrimal duct in treatment of obstructive diseases of lacrimal duct in our hospital was 85.8%.There was significant difference in the factors as age'portion of obstruction'having or not purulent discharge and special management in or afteroperation'and otherwise in the factors as progress and sex.Conclusion Age'portion of obstruction'having or not purulent discharge and special management in or after operation are the important affect factors to the effect of laser plastic operation of lacrimal duct.

利用激光治疗阻塞性泪道疾病自1995年在全国广泛开展以来取得了良好效果。虽然泪道激光成形术具有许多优点,然而其最终疗效仍不能令人满意。笔者拟通过对临床开展的泪道激光成形术患者进行回顾性研究以了解影响泪道激光成形术疗效的因素,以供临床中选择性地进行泪道激光成形术。

1 资料与方法

1.1 一般资料 我院自2002年9月以来门诊及住院患者103例(106眼),男6例,双眼1例;女97例,双眼2例。年龄24~76岁,平均(48.36±14.08)岁。病程6个月~20年,平均(4.95±3.67)年。泪总管及以上阻塞者8眼,泪囊及以下阻塞者84眼,上、下泪道多处阻塞(混合性)者14眼;其中有脓性分泌物者96眼。曾行泪道探通插管治疗后复发11眼,行泪道激光成形术后复发3眼。

1.2 方法

1.2.1 激光成形术方法 泪道注入1%丁卡因黏膜表面麻醉,扩张泪小点及泪小管后插入套针至阻塞部位后插入Nd∶YAG激光(华工HD-110型)光导纤维边激光击射边向下前进,直至顺利到达鼻腔;泪道冲洗通畅后一边注入典必殊眼膏,一边退出套针。术后第2天每日泪道冲洗1次,连续5天后逐渐减少冲洗频率至1个月。

1.2.2 术中术后特殊处理 (1)贝复舒眼液:激光打通泪道后以0.5ml贝复舒眼液缓慢冲洗泪道2min后再注入典必殊眼膏,术后每日泪道冲洗后以0.5ml贝复舒眼液缓慢冲洗泪道,配合滴贝复舒眼液每日4次,连续3天;(2)泪道插管:激光打通泪道后采取套环式泪道置入硅胶管[1],留置3~6个月;(3)泪道扩张:如泪道激光术后泪道冲洗不畅,采取每周行2次泪道插管扩张泪道。

1.2.3 疗效标准[2] 在泪道激光成形术后3个月判断疗效。治愈:泪溢症状消失,泪道冲洗通畅,无液体反流;好转:泪溢症状减轻,泪道冲洗通而不畅,有少许液体反流;无效:泪溢症状无缓解,泪道冲洗不通,液体甚至黏脓性分泌物反流。

1.3 统计学方法 数据采用SPSS 10.0软件进行方差等统计学处理。

2 结果

2.1 一般资料统计 见表1。

表1 泪道激光成形术治疗阻塞性泪道疾病患者的一般资料 (眼)

2.2 泪道激光成形术治疗阻塞性泪道疾病的疗效分析 治愈70眼,治愈率为66.0%;好转21眼,好转率为19.8%;无效15眼,占14.2%。总有效率为85.8%。单纯泪道激光治疗共41例,好转率为75.6%;术中联合应用贝复舒好转率为94.1%;术后泪道扩张好转率为80.0%;术中术后联合泪道插管转率为90.5%。

2.3 各因素对治疗疗效影响的分析 将上述资料用SPSS 10.0软件进行方差分析,结果表明对泪道激光成形术疗效的影响差异具有显著性的因素有:年龄(F=7.256,P<0.001),阻塞部位(F=4.382,P<0.05),有无脓性分泌物(F=5.981,P<0.01),术中术后特殊处理(F=3.595,P<0.05);性别(F =0.643,P>0.05)和病程(F=1.195,P>0.05)对治疗疗效的影响差异无显著性。
