方法：选取2012-03/2015-03间入院诊治的复发泪囊炎患者80例80眼。根据随机数表法将患者分为试验组(40例)和对照组(40例)，其中试验组应用泪道激光吻合口成形联合U形泪道扩张管植入术治疗，对照组应用常规经皮肤切口的泪囊鼻腔吻合术治疗。观察两组患者的治疗效果与手术指标。

结果：试验组经治疗后治愈28例，好转5例，总有效率为82%； 对照组治愈15例，好转13例，总有效率为70%。试验组手术时间为40.06±1.35min，术中出血量5.37±1.28mL，留院观察26.28±3.42h； 对照组则分别为90.14±2.61min，14.47±6.19mL，98.14±10.53h。

结论：泪道激光吻合口成形联合U形泪道扩张管，较之常规经皮肤切口的泪囊鼻腔吻合术对于复发性泪囊炎患者的治疗效果更好，具有损伤小、操作性高、安全性好、治愈率高等优点。

METHODS:Eighty patients(80 eyes)with recurrent dacryocystitis admitted to our hospital for diagnosis and treatments from March 2012 to March 2015 were selected. According to a random number table, they were divided into experimental group(40 cases)and control group(40 cases). The experimental group received laser dacryocystorhinostomy combined with U-shaped lacrimal duct implantation. Patients in control group were treated with conventional dacryocystorhinostomy with skin incision. The effect of the treatments and surgical indicators of the two groups were observed and compared.

RESULTS:In experimental group, there were 28 cases were cured after treatment, 5 cases were improved, the total effective rate was 82%. In control group, there were 15 cases were cured, 13 cases were improved, the total effective rate was 70%. The operation time of experimental group was 40.06±1.35min, blood loss was 5.37±1.28mL, the time of remaining in hospital under observation was 26.28±3.42h; those of the control group were 90.14±2.61min, 14.47±6.19mL, 98.14±10.53h, respectively.

CONCLUSION:Laser dacryocystorhinostomy combined with U-shaped lacrimal duct implantation is more effective, more easy to operate, safer and has less injury and higher cure rate.
