Purpose:
To investigate the long-term efficacy of dacryoendoscopy-guided recanalization and silicone tube intubation in patients with obstruction in the lacrimal drainage system and to identify factors related to surgical outcome.
Methods:
We retrospectively reviewed the medical records of patients with primary nasolacrimal duct obstruction and canalicular obstruction who underwent dacryoendoscopy-guided recanalization and silicone tube intubation between August 2014 and March 2016. Factors related to surgical outcome were examined and compared between the success group (eyes with complete response and partial response) and the failure group. Kaplan-Meier survival analysis and multivariable logistic regression analysis were used to analyze the success rate according to the factors found to have statistical significance.
Results:
The study included 74 eyes of 51 patients. The mean age of the patients was 60.3 ± 10.0 years (range, 34-80 years). The success group consisted of 66 eyes (89.2%) (complete response, 56 eyes, 75.7%; partial response, 10 eyes, 13.5%) and the failure group consisted of eight eyes (10.8%). The median follow-up period was 58 months (range, 6.5-72 months), and the overall success rate was 89.2%. Compared to the eyes with preoperative lacrimal irrigation test of partial passage, the eyes with no passage were associated with a lower success rate (95.9% vs. 76.0%, p = 0.01). Postoperative inflammation was also associated with a lower success rate (96.6% vs. 60.0%, p < 0.001).
Conclusions:
Dacryoendoscopy-guided recanalization and silicone tube intubation is effective and can be considered a first choice of treatment for eyes which show partial passage in the lacrimal irrigation test. The management of postoperative inflammation is essential to ensure surgical success.
