Abstract:
PURPOSE: This article analyzes the microorganisms and antibiotics susceptibility in dacryocystitis. METHODS: In this study, patients who were diagnosed with acute and chronic dacryocystitis with nasolacrimal duct obstruction were selected and underwent endoscopic endonasal dacryocystorhinostomy. Cultures were obtained from the lacrimal sac during operation from January 2008 to January 2016, and were used to analyze the microorganisms and antibiotics susceptibility. RESULTS: The 67 patients, 9 were diagnosed with acute dacryocystitis and 58 were diagnosed with chronic dacryocystitis. Among them, 64 cases showed bacterial growth (95.5%). The most frequently detected bacteria was Staphylococcus epidermidis (S. epidermidis) (33.8%), followed by Staphylococcus aureus (S. aureus) (25.4%) and Enterobacter aerogenes (18.3%). S. epidermidis had the most powerful resistance to ciprofloxacin compared to the other bacteria (58.3%, p = 0.02). Except for S. epidermidis and S. aureus, the other bacteria responded to ciprofloxacin and gentamycin. CONCLUSIONS: As a causative microorganism of dacryocystitis, S. epidermidis is becoming more prominent, and it is thought that S. epidermidis may be resistant to quinolones (i.e., broad-spectrum antibiotics). This resistance might be increasing the percentage of present S. epidermidis when viewed as a causal pathogen in dacryocystitis.
