目的探讨泪道内窥镜在诊断及治疗泪小管结石中的作用。方法回顾性分析32例（32只眼）泪小管结石的临床资料。在泪道内窥镜直视下探查泪小管发现泪小管结石后，直径〈2mm的结石在泪道内窥镜下冲洗人鼻腔，直径≥2mm的结石及伴有泪小管息肉者，进行部分泪小管切开术。若泪囊内伴有结石，较小的泪囊结石则在泪道内窥镜下冲洗人鼻腔，较大的泪囊结石采取泪囊切开术，若同时伴有泪囊炎，则选择改良泪囊鼻腔吻合术，术中同时置入双泪小管置入式人工泪管。术后3—6个月拔管，拔管后随访6个月至1年。结果2例应用泪道内窥镜冲洗至鼻腔，11例伴有泪小管息肉者和15例泪小管巨大结石者，行部分泪小管切开术，1例合并泪囊结石者应用泪道内窥镜冲洗至鼻腔，1例合并泪囊结石者行泪囊切开术，2例合并泪囊结石伴有泪囊炎者行改良泪囊鼻腔吻合术。治愈30例（93．75％），好转2例（6．75％）。结论泪道内窥镜在诊断和治疗泪小管结石中有较大价信．

英文摘要：

Objective To evaluate the diagnosis and treatment of canalicular concretions by using transeanalicular endoscope. Methods The clinical data of 32 patients （32 eyes） who suffered eanalieular concretions were retrospectively studied. The canaliculi of 32 eyes of 32 patients were searched directly by u- sing transcanalicular endoscope. When we found the canalicular concretions, the concretions with diameter 〈 2 mm were irrigated into nasal cavity by using transcanalicular endoscope, the concretions with diameter≥2 mm or canalieular polyp were extracted by partial eanaliculotomy. If we found the concretions in the dacryo- cyst, the smaller concretions were irrigated into nasal cavity by using transcanalieular endoscope, the bigger concretions were extracted by daeryocystotomy and if with dacryoeystitis, the patiens were treated by modified dacryocystorhinostomy, simultaneously the bieanalicular silicone stents were imbeded. The stents were pulled out after the operations from 3 months to 6 months, and the patients were followed up for 6 months to 1 year. Results The concretions were irrigated into nasal cavity by using transcanalicular endoscope in 2 cases, the concretions with eanalicular polyp in 11 cases and the big stones in 15 cases were extracted by partial canaliculotomy. The concretions in dacryocyst were irrigated into nasal cavity by using transcanalicular endo- scope in 1 case, and the concretions were extracted by dacryocysistomy in 1 case, 2 cases were treated by modified dacryoeystorhinostomy with dacryocystitis. 30 cases were cured（ 93.75% ）. 2 cases were improved （6.75%）. Conclusion Transcanalicular endoscopy has great value in the diagnosis and treatment of canalieular concretions.
