Objectives
To compare the results of immediate endoscopic dacryocystorhinostomy (En-DCR) and delayed En-DCR in the treatment of new-onset acute dacryocystitis (AD).
Study Design
This report describes a prospective randomized controlled interventional case series.
Methods
Between April 2009 and May 2019, 176 adults presenting at a tertiary eye care center with new-onset AD manifesting within the last 48 hours were randomized into two groups. Altogether, 160 patients (48 male, 112 female) were included in this study, with a median age of 52.8 years (range: 18–82). Patients in group A underwent urgent En-DCR, although those in group B underwent a delayed En-DCR after 2 to 5 days of systematic antibiotic treatment. Variables compared between these two groups included the time for resolution of acute external inflammation, free lacrimal passage reconstruction (LPR) success rates, and complication rates.
Results
Postoperative data were collected from 86 patients in group A and 74 patients in group B. Patients that underwent immediate En-DCR exhibited a quicker resolution of acute inflammation (P < .05). Patients that underwent delayed surgery experienced compilations of acute inflammation, with 10 ultimately developing skin fistulization and 4 exhibiting orbital cellulitis before surgery. The success rate of LPR at 12 months after surgery was higher in group A (81/86 94.2%) relative to group B (62/74 83.8%; P < .05).
Conclusions
Immediate En-DCR is associated with quicker disease resolution and a higher long-term success rate, although reducing the incidence of complications including skin fistulization and the spread of infection.
