人工泪管置入术后复发原因分析

目的探讨人工泪管置入术治疗泪道阻塞性疾病术后复发的原因。方法观察66例76眼泪道阻塞性疾病行人工泪管置入术,术后随访1～3年。结果 30只泪囊炎患眼手术治疗后,3眼无效,占4%;14只泪小管阻塞患眼手术治疗后,3眼无效,占4%;余32只患眼手术治疗有效。具有2个以上阻塞节点的15只患眼手术治疗后,6眼无效,余61只患眼手术治疗有效。与鼻部疾病相关的24只患眼手术治疗后,6眼无效;余52只患眼手术治疗有效。阻塞节段为多发和或鼻部伴有病变者未治愈率明显高于单一位点阻塞及无鼻部病变患者,差异有统计学意义。结论泪囊炎、泪小管阻塞、多节点阻塞等因素是人工泪管置入术后复发的主要原因。

Analysis of Causes of Postoperative Recurrence after Implantation of Artificial Lacrimal Duct

Objective To investigate the causes of recurrence of lacrimal duct obstruction after the implantation of artificial lacrimal duct.Methods 66 cases(76 eyes)with lacrimal duct obstruction receiving artificially tear duct implantation were observed,follow-up of 1-3 years.Results The operation was ineffective in 3 eyes out of 30 dacryocystitis eyes,accounting for 4%,in 3 eyes out of 14 lacrimal duct obstruction eyes accounting for 4%;effective in the remaining 32 eyes.The operation was ineffective in 6 eyes out of the 15 eyes with over 2 obstruction nodes;effective in the remaining 61 eyes.The operation was ineffective in 6 eyes out of 24 eyes associated with nasal diseases;effective in the remaining 52 eyes.The ineffective rate of cases with multiple-node obstruction and/or nasal diseases was obviously higher than the cases with single obstruction site and no nasal diseases with statistical significance.Conclusion Dacryocystitis,lacrimal duct obstruction,and obstruction of multi-node etc.are the main causes of recurrence of artificial tear ducts implantation.
