方法：选择2008-05/2010-05在我院诊治的107例慢性泪囊炎患者为研究对象，随机分组，观察组(内窥镜下泪道钻通联合置管术治疗组)54例，对照组(外路泪囊鼻腔吻合术治疗组)53例，比较两组慢性泪囊炎患者治疗后的效果。

结果：观察组治愈率为74.1%，与对照组比较差异不显著(P>0.05)； 并发症发生率为38.9%、术后1a内复发率为5.6%，明显低于对照组，差异明显(P<0.05)。

结论：内窥镜下泪道钻通联合置管术治疗慢性泪囊炎不仅有效、安全，同时具有微创的特点，适合在临床应用。

METHODS: From May 2008 to May 2010, 107 patients with chronic dacryocystitis were selected as objects in our hospital. They were randomly divided into observation group and control group. Observation group(endoscopic lacrimal drill combined with intubation group, n=54)and control group(external-route lacrimal sac and nasal cavity anastomosis group, n=53). Their clinical effects were compared after the treatment.

RESULTS: In observation group, the cure rate was 74.1%, it was not significant when compared with the control group(P>0.05); the complication rate was 38.9%, the recurrence rate was 5.6% for 1 year after the surgery, it was significantly lower than the control group, there was a sharp distinction(P<0.05).

CONCLUSION: The endoscopic lacrimal drill combined with intubation for the treatment of chronic dacryocystitis is effective, safe as well as minimal invasion. It was suitable for clinic.
