To compare the success rates of endoscopic transcanalicular diode laser dacryocystorhinostomy (EL-DCR) and external DCR.
Operations were performed on 55 eyes of 54 patients who had distal nasolacrimal canal obstruction. External DCR was performed on 29 of the eyes and EL-DCR on 26 of them. Success was defined based on subjective relief of patients reported at their final examinations.
There were 23 women and 6 men in group 1 and 19 women and 6 men in group 2 (p = 0.77). The mean ages of groups were 45.24 ± 12.08 (range, 15-74) and 43.2 ± 17.01 (range, 11-72) years, respectively (p = 0.63). The mean follow-up times were 8.82 ± 5.51 (range, 3-18) and 7.12 ± 2.96 (range, 2-12) months, respectively in groups (p = 0.58). The success rates based on symptoms were measured at 25 of 29 (86%) and 17 of 25 (68%) for 2 groups. The difference in the success rates was higher but not found to be statistically significant (p = 0.202). The authors found various conditions related to nasal passage in 4 of 8 unsuccessful EL-DCR, including allergic rhinitis, nasal crust, silicone tube reaction, and unsuitable passage for endoscopic surgery.
The success rate of EL-DCR was lower than that of the external DCR; however, no statistically significant difference was observed. Endoscopic transcanalicular diode laser DCR may be considered as an alternative method to external DCR with these results.
比较经鼻内窥镜下钬激光泪囊鼻腔吻合术（EL-DCR）和外路泪囊鼻腔吻合术的成功率。
对 54 例 55 只患有下泪道阻塞的患者进行了手术。其中 29 只眼行外路泪囊鼻腔吻合术，26 只眼行 EL-DCR。根据患者最终检查时的主观缓解情况定义手术成功。
第 1 组有 23 名女性和 6 名男性，第 2 组有 19 名女性和 6 名男性（p = 0.77）。第 1 组的平均年龄为 45.24 ± 12.08 岁（范围 15-74 岁），第 2 组为 43.2 ± 17.01 岁（范围 11-72 岁）（p = 0.63）。第 1 组的平均随访时间为 8.82 ± 5.51 个月（范围 3-18 个月），第 2 组为 7.12 ± 2.96 个月（范围 2-12 个月）（p = 0.58）。根据症状评估，第 1 组的成功率为 29 例中的 25 例（86%），第 2 组为 25 例中的 17 例（68%）。虽然成功率差异较大，但无统计学意义（p = 0.202）。作者发现，在 4 例 EL-DCR 不成功的病例中存在与鼻道相关的各种情况，包括变应性鼻炎、鼻痂、硅胶管反应和不适合内镜手术的通道。
EL-DCR 的成功率低于外路泪囊鼻腔吻合术，但无统计学差异。基于这些结果，EL-DCR 可被视为外路泪囊鼻腔吻合术的替代方法。
