简介：目的观察泪道探通联合硅胶管植入术治疗慢性化脓性泪囊炎的临床疗效。方法对30例（32眼）慢性化脓性泪囊炎患者行泪道探通联合硅胶管植入术，术后随访3—6个月。结果植入成功率100％。4眼于术后4-7d发生阻塞，及时行泪道冲洗后恢复通畅。硅胶管留置期间，其中溢泪、溢脓症状完全消除28眼，另外4眼仍有轻度溢泪。取出硅胶管后复发5眼占15％，治愈23眼，好转4眼，总有效率84％。结论应用硅胶管植入术治疗慢性化脓性泪囊炎手术时间短，出血少，安全性高，具有肯定的临床效果。值得推广。

简介：目的观察泪道探通后氟尿嘧啶应用联合鼻泪管中逆行植入球头硅胶管术治疗慢性泪囊炎的临床疗效。方法从门诊就诊的泪道阻塞患者中,选取泪点泪小管均通畅的慢性泪囊炎患者42例（56只眼）,随机分为实验组与对照组,治疗组采用先泪道探通扩张,并将氟尿嘧啶溶液浸入阻塞创面,后经鼻腔逆行植入球头硅胶管术治疗,对手术疗效进行分析。对照组则不采用氟尿嘧啶干预措施,其余治疗与对照组相同。两组患者均于术后3个月拔管。结果拔管后随访3～12个月,治疗组21例（29只眼）中有效25只眼,泪道冲洗通畅无分泌物,2只眼冲洗欠通畅无分泌物,2眼泪道冲洗仍阻塞,治愈率86.2%。对照组21例（27只眼）中有效17只眼,泪道冲洗通畅无分泌物,4只眼冲洗欠通畅无分泌物,6眼泪道冲洗仍阻2塞,治愈率63.0%。经χ检验治疗组治愈率高于对照组（P〈0.05）。结论泪道探通联合球头硅胶管逆行植入术治疗慢性泪囊炎具有操作简便、不切皮肤、不损伤组织结构等优点,临床疗效肯定。氟尿嘧啶对于预防泪道阻塞部位创面再次粘连,提高远期疗效有确切作用。
