To evaluate treatment of epiphora due to acquired stenotic obstruction of the nasolacrimal duct system with dacryocystoplasty (DCP), in which balloon dilation is used to alleviate the obstruction.
Twenty patients (21 eyes) with epiphora due to obstructing lesions at the saccular or subsaccular level were treated with DCP. The authors used a catheter with a balloon diameter of only 3 mm to prevent damage to the nasolacrimal duct system and a nontraumatizing guide wire. Stent placement was not considered necessary. Follow-up ranged from 14 to 70 weeks.
Cannulation was not possible in one case of complete obstruction. DCP was successfully performed in the other 20 cases. In 18 of these cases (90%), results comparable with those of dacryocystorhinostomy were achieved. No side effects were observed.
DCP is potentially the treatment of choice for epiphora due to acquired stenotic obstruction of the nasolacrimal duct system.
评估采用泪囊成形术（DCP）治疗因后天性鼻泪管系统狭窄阻塞所致溢泪症的效果，该手术通过球囊扩张来缓解阻塞。
20例（21只眼）因泪囊或泪囊以下水平阻塞性病变导致溢泪的患者接受了泪囊成形术治疗。作者使用球囊直径仅3毫米的导管以防止损伤鼻泪管系统，并使用无创伤导丝。未考虑放置支架。随访时间为14至70周。
1例完全阻塞患者无法进行插管。其他20例成功进行了泪囊成形术。其中18例（90%）取得了与泪囊鼻腔吻合术相当的效果。未观察到副作用。
泪囊成形术可能是治疗因后天性鼻泪管系统狭窄阻塞所致溢泪症的首选方法。
