【摘要】 目的：应用气囊导尿管、明胶海绵应用于泪囊鼻腔吻合术中的临床疗效。方法：将慢性泪囊疾病患者200例(200眼)按照随机的原则分成2组：A组(气囊导尿管组)100眼，B组(明胶海绵组)100眼,观察手术后连续1mo溢泪及冲洗泪道通畅情况。结果：A组中治愈99眼(99%)；B组中治愈93眼(93%)。两组疗效及并发症，差异有显著意义(P <0.05)。结论：气囊导尿管治愈率较高，充填吻合道，对止血、防止粘连、抑制纤维化及减轻吻合口收缩起重要作用，是较为安全，有效，使用方便理想的留置物。

Abstract AIM: To evaluate the clinical effect of two different filling material on treating chronic dacryocystitis：aerocyst urethral catheter, compressed gelatin sponges. METHODS: Two hundred patients(200 eyes)with chronic deacryocystis disease were divided into two groups：group A(100 eyes) accepted aerocyst urethral catheter as a filling material in EXTDCR，group B(100 eyes)accepted compressed gelatin sponges. The condition of epiphora and syringing of the lacrimal passage were observed in the first month after the operation continuous1y. RESULTS: There were 99 eyes cured (99％) in group A and 93 eyes cured(93％) in group B .There was significantly statistical difference between the two groups in the surgical success rate and the operative complications (P <0.05). CONCLUSION: It is believed that the with higher success rate in Group A，fewer operative complications and a high patient satisfaction can be used to simplify and speed up traditional EXTDCR．aerocyst urethral catheter play a important function in stopping hemorhage and preventing adhesion and inhabiting fibrous tissue growth and reducing contraction of anastomosis．Aerocyst urethral catheter is a safe, effective and ideal filling material for treatment of chronic deacryocystis disease, which can be cured or improved．
· KEYWORDS: aerocyst urethral catheter；chronic dacryocystitis；dacryocystorhinostomy
0引言
慢性泪囊疾病是眼科常见的泪器病,而泪囊鼻腔吻合术是其治疗的首选方法。由于泪总管开口和骨孔处纤维组织增生，肉芽和瘢痕形成等常见原因，仍有部分病例术后失败.另外术后吻合口骨窗过小、吻合口中血凝块、吻合瓣过松及瓣缝线脱落均可引起吻合口的阻塞，导致手术失败。为了提高手术成功率，减少术后出血，使吻合口腔足够大，术后置放何种引流物于吻合腔内也就至关重要.我院2002/2005年分别采用气囊导尿管和明胶海绵两种材料治疗200例慢性泪囊疾病, 采用两样本t 检验对其基本资料、临床疗效等方面进行比较分析。现报告如下。
