Optimal Timing for Primary Early Endoscopic Dacryocystorhinostomy in Acute Dacryocystitis

Purpose: To evaluate the surgical outcomes of primary early endoscopic dacryocystorhinostomy (EnDCR) in acute dacryocystitis (AD) and to determine optimal timing for surgery. Methods: A retrospective review medical records was performed on consecutive patients who underwent EnDCR (within 1 week) AD between May 2010 June 2020 (AD group) an age- gender-matched control group NLDO (non-AD group). The outcome measures were at final follow-up examination. secondary measure clinical course patients. Subgroup analysis surgery by comparing very 3 days) those (between 4 7 days). Results: Forty-one included 82 non-AD group. anatomical functional success rates 87.8% 82.9% group, 91.5% 84.1% which not significantly different two groups (p = 0.532 p 0.863). In mean times pain relief resolution swelling after 2.4 6.5 days surgery, respectively. subgroup according time symptom diagnosis, length hospital stays, duration antibiotic treatments shorter (all ps < 0.05), whereas 1.000). Conclusions: Primary is a safe effective procedure treatment AD. particular, within leads faster recovery shortens treatment.
