Li EY, et al. - A comparative scrutiny was conducted of the outcomes of endoscopic dacryocystorhinostomy (EN-DCR) as primary treatment with EN-DCR as a secondary treatment after percutaneous drainage of lacrimal sac abscess in acute dacryocystitis. A faster resolution was achieved via the primary EN-DCR in acute dacryocystitis with lacrimal sac abscess than with secondary treatment. The data did not illustrate any variations in the recurrence, safety, or outcomes at postoperative year 1, between the 2 treatment groups.
