Optimal Timing for Primary Early Endoscopic Dacryocystorhinostomy in Acute Dacryocystitis
Abstract Purpose: To evaluate the surgical outcomes of primary early endoscopic dacryocystorhinostomy (EnDCR) in acute dacryocystitis (AD) and to determine the optimal timing for surgery.Methods: A retrospective review of the medical records was performed on consecutive patients who underwent primary early EnDCR (within 1 week) for AD between May 2010 and June 2020 (AD group) and age- and gender-matched control group of NLDO patients who underwent EnDCR (non-AD group). The primary outcome measures were surgical outcomes at the final follow-up examination. The secondary outcome measure was clinical course of AD patients. Subgroup analysis was performed to determine the optimal timing of surgery by comparing outcomes of very early EnDCR (within 3 days) and those of early EnDCR (between 4 and 7 days).Results: Forty-one patients were included in the AD group and 82 patients in the non-AD group. The anatomical and functional success rates were 87.8% and 82.9% in the AD group, and 91.5% and 84.1% in the non-AD group, which were not significantly different between the two groups (p = 0.532 and p = 0.863). In the AD group, the mean times for pain relief and resolution of swelling after surgery were 2.4 and 6.5 days after surgery. In subgroup analysis according to the timing of surgery, the time for symptom resolution after diagnosis, the length of hospital stay, and the duration of antibiotics treatment were significantly shorter after very early EnDCR (all ps < 0.05), whereas the surgical outcomes were not different between the 2 groups (p = 1.000)Conclusions: Primary early EnDCR is a safe and effective procedure for the treatment of AD. In particular, very early EnDCR, performed within 3 days, leads to faster recovery and shortens the course of antibiotic treatment.
