Abstract
Purpose: To compare the effect of endoscopic and external dacryocystorhinostomy (EN and EX-DCR) for treating dacryocystitis
in Chinese adult population.
Methods: A retrospective, multi-center case series was conducted. A total of 185 eyes out of 167 patients suffered from either
chronic or acute dacryocystitis were enrolled in this study. Patients were treated in one of the three regional hospitals from January
to December of 2016. The patients were reviewed for demographic characteristics, clinical presentation, and management outcome.
The primary surgery success was defined as having an anatomical success without any revision surgery. The final surgery success
was defined as having an anatomical success after all surgeries (including repeated surgeries).
Results: Enrolled patients included a total of 112 eyes out of 102 patients who underwent EN-DCR, and 73 eyes out of 65
patients who accepted EX-DCR. The primary surgery success rate was 89.29% (100/112) for EN-DCRs and 89.04% (65/73) for
EX-DCRs. The Kaplan-Meier survival analysis showed no statistical difference in primary surgical outcomes between these two
approaches, with a log rank X2 of 0.369 (P=0.543). Repeated EN-DCR was accepted by the patients with primary surgical failures in
both EN- DCR (12/12) and EX-DCR (8/9) groups, leading the final surgical success rate of the EN-DCR and EX-CR group at 97.32%
and 97.26%, respectively. The final surgical success rate was statistically significantly higher than the primary success rate in each
group.
Conclusion: N-DCR is a valid alternative to external procedure in the management of dacryocystitis in the Chinese adult
population, because of the comparable primary success rate to external approach and the unique advantages in treating the patients
that need repeated surgeries.
