新型RS泪道硅胶管在泪小管断裂吻合中的应用

Application of new RS lacrimal duct silicone tube for lacrimal canalicular laceration

目的 探讨新型RS泪道硅胶管在泪小管断裂吻合中的临床疗效.方法 收集本院眼科于2014年5月至2017年5月期间手术治疗的泪小管断裂伤患者62例62眼,其中下泪管断裂58例,上泪管断裂1例,上下泪管均断裂3例,所有患者均在显微镜直视下寻找泪小管鼻侧断端,所有患者均使用新型RS泪道硅胶管作为管腔支撑物,术后3月拔管,拔管后随访3～6月,观察临床疗效.结果 62例患者62只眼手术顺利,全部吻合成功,手术时间35～55 min,拔管后随访时间3个月评估：62只眼中56只眼治愈,无溢泪,泪道冲洗通畅;4只眼好转,轻微溢泪,泪道冲洗通而不畅;2只眼无效,溢泪,泪道冲洗不通.总有效率为96.8％（60/62）.结论 新型RS泪道硅胶管应用于外伤性泪小管断裂吻合的临床疗效可靠,操作简便,手术时间短,手术成功率高,术后并发症少,值得临床推广应用.

Objective To investigate the clinical effect of new RS lacrimal duct silicone tube in treating lacrimal canalicular laceration.Methods From May 2014 to May 2017,62 cases （62 eyes） of lacrimal canalicular laceration were collected and studied in department of ophthalmology of our hospital,in whom there were 58 cases with inferior canalicular laceration,1 case with superior canalicular laceration,and 3 case with superior and inferior canalicular laceration.All patients were treated by lacrimal duct anastomosis with new RS lacrimal duct silicone tube under the microscope.The tubes were removed 3 months later and all patients were followed up for 3-6 months.Observed the clinical effect.Results Surgeries in all 62 cases （62 eyes） were successful and the operation lasted 35 to 55 minutes.After 3 months of follow-up,56 eyes were cured,4 eyes improved,and 2 eyes was ineffective,the total effective rate was 96.8% （60/62）.Conclusion New RS lacrimal duct silicone tube is effective for lacrimal canalicular laceration,with simple operating procedure,short operation time,high successful rate,few complications,which should be promoted clinically.
