Acute versus late endoscopic dacryocystorhinostomy in treatment of acute dacryocystitis: A prospective randomised trial with an 18-month follow-up.

PURPOSE

To compare the long-term symptom resolution and use of resources of performing endoscopic dacryocystorhinostomy (enDCR) in acute or delayed phase in patients with acute dacryocystitis (AD).

METHODS

This prospective, randomised controlled trial was conducted in Helsinki University tertiary Eye and Ear, Nose and Throat (ENT) Hospitals between September 2013 and January 2019. Fifty patients aged 18 and above presenting with AD in the emergency care were randomised into acute and delayed enDCR surgery groups, performed in 1 week or 4 months from the diagnosis of AD. The follow-up time was 18 months. Outcome measures were subjective epiphora, lacrimal symptoms and visual analogue scale (VAS) pain scores, the number of hospitalised and unhealthy days, use of medication and openness in lacrimal syringing and dye test.

RESULTS

EnDCR was performed on 24 patients in the acute and 19 in the delayed group. There were no significant differences between the groups in follow-up lacrimal symptoms, syringing test, dye test or use of resources. At the 18 months' follow-up, 21/23 (91.3%) in the acute group and 12/13 (92.3%) in the delayed group had no disturbing lacrimal symptoms. When reoperations and dropouts are considered, beneficial outcome was 22/24 (91.7%) in the acute and 12/16 (75%) (p = 0.195) in the delayed group. The acute group had significantly fewer pain medication days than the delayed group, 3 versus 10.5 (p = 0.03).

CONCLUSION

Acute enDCR is associated with fewer pain medication days and equal resolution of lacrimal symptoms and use of resources.
