Purpose: To compare characteristics in patients with and without previous dacryocystitis and satisfaction after endoscopic dacryocystorhinostomy. Methods: We retrospectively analyzed 156 eyes of 116 patients who underwent endoscopic dacryocystorhinostomy at our Hospital from May 2011 to December 2015. The patients were grouped into those with pre-operative dacryocystitis and those without dacryocystitis. Each patient group was characterized retrospectively, followed by a telephone survey regarding post-operative satisfaction. Results: Fifty-eight patients (66 eyes) had dacryocystitis, whereas 58 patients (90 eyes) did not. Patients' mean age was 64.9 years old. The mean duration of symptoms in patients with and without dacryocystitis was 11 and 20 months, respectively, showing a statistically significant difference (p < 0.05). The correlation between comorbidities and dacryocystitis was statistically insignificant (p > 0.05). Post-operative satisfaction was higher in patients with dacryocystitis, showing a statistically significant difference (p < 0.05). Conclusions: Patients with pre-operative dacryocystitis were characterized by a shorter duration of symptoms and higher post-operative satisfaction. This finding implies that post-operative satisfaction could be lower in patients without dacryocystitis, which should be noted. J Korean Ophthalmol Soc 2017;58(1):1-6
