Comparison Results of Silicone Tube Intubation According to Syringing and Dacryocystography

Purpose: To compare the surgical success rate of silicone tube intubation according to the preoperative lacrimal syringing test and dacryocystography (DCG) in adult patients with epiphora. Methods: Medical records of 142 patients who underwent silicone tube intubation were retrospectively reviewed. The surgical results were divided into 3 groups based on postoperative symptoms and the syringing test results: Good, Fair, and Fail. Good and Fair were classified into the surgical success groups. We compared the surgical success rate according to the preoperative syringing test and stenosis site observed on dacryocystography. Results: The success rates of silicone tube intubation were 88.4% and 87.4% in eyes with preoperative syringing results of totally- passed and partially-passed syringing tests, respectively, revealing no statistically significant differences (<EM>p </EM>= 0.838, chisquare test). However, in eyes with the preoperative syringing results of partially-passed syringing tests, the success rates were 66.7% in patients with canalicular stenosis, 83.3% in patients with nasolacrimal duct stenosis, and 94.5% in those with diffuse stenosis (<EM>p </EM>= 0.018, chi-square test). Conclusions: No significant differences were found in the success rates of silicone tube intubation according to preoperative syringing test results. However, when considered together with DCG findings, the lowest success rate was found in eyes with the partially-passed syringing test and simultaneously showed canalicular stenosis on DCG. The syringing test results considered with DCG findings may help predict the success rates of silicone tube intubation.&nbsp;J Korean Ophthalmol Soc 2014;55(11):1584-1588
