Abstract

Background: Endoscopic dacryocystorhinostomy (EN-DCR) is an effective procedure when treating saccal and postsaccal obstructions of the nasolacrimal pathway. The benefit of silicone tubing after DCR is still controversial. We conducted a prospective, randomized study to evaluate the necessity of bicanalicular silicone tubes after primary EN-DCR.

Methods: Forty-six consecutive primary EN-DCR procedures were performed in 42 patients during 2004-2007. The patients were randomized into two study groups according to whether silicone tubing was used or not.

Results: The overall success rate after primary EN-DCR was 89%: with silicone tubes it was 78%, and without silicone tubes it was 100%. The difference between these two groups was statistically significant (p<0.049). The follow-up period was 6 months and included three follow-up visits: 1 week, 2 months, and 6 months postoperatively. If inserted, the silicone tubes were removed at the 2-month visit.

Conclusion: The results of our prospective, randomized study showed that the use of silicone tubes after primary EN-DCR is not necessary.

初次内窥镜泪囊鼻腔造口术后不需要硅胶管:一项前瞻性随机研究。

背景:内窥镜下泪囊鼻腔造口术(EN-DCR)是治疗鼻泪道囊及囊后阻塞的有效方法。硅胶管DCR后的效益仍有争议。我们进行了一项前瞻性随机研究，以评估原发性EN-DCR后双管硅胶管的必要性。方法:2004-2007年间，42例患者连续行46例EN-DCR手术。根据是否使用硅胶管将患者随机分为两个研究组。结果:一期EN-DCR的总成功率为89%，其中硅胶管组为78%，无硅胶管组为100%。结论:我们的前瞻性随机研究结果显示，EN-DCR术后没有必要使用硅胶管。
