INDICATIONS AND OUTCOME OF EXTERNAL DACRYOCYSTORHINOSTOMY (EXT DCR) AT NATIONAL EYE CENTRE (NEC) KADUNA, NIGERIA: A TENYEAR REVIEW
Keywords:– Outcomes, Indications, Dacryocystorhinostomy, Nasolacrimal duct obstruction
Aim - to evaluate the outcome of external DCR at the Nigeria’s National Eye Centre.
Method – a descriptive retrospective cross-sectional study where clinic and theatre records of
patients who had DCR from 2010 – 2019 were reviewed. Information obtained include: Sociodemographic data, chief complaint, duration of symptoms prior to presentation and after
surgery, presence or absence of regurgitation on pressure over lacrimal sac (ROPLAS sign) before
and after surgery, duration of stent before removal, indications for surgery and complications of
surgery. Data obtained were entered into excel sheet and descriptive statistics done.
Results – information was obtained from records of 139 patients, 87 (62.6%) were males with a
M: F of 1.67: 1. The mean age of participants was 29years +/- 13.1 SD while the modal age group
was 21–30. Epiphora was the predominant presenting symptom which majority endured for up
to 4–6 years before presentation to hospital. Traumatic nasolacrimal duct obstruction was the
most common indication for surgery (39%). Other indications were chronic dacryocystitis,
congenital NLDO, and primary acquired NLDO. There was a 96.4% success rate in the first 6
months post DCR with only 5 patients (3.6%) symptomatic at the 6 months follow-up visit. The
major complications recorded were nasal oedema, intraoperative bleeding, failure, infection and
premature stent extrusion.
Conclusion – this study has shown that external DCR is a safe therapeutic procedure for NLDO
with a very high success rate. It is still the treatment of choice in resource limited settings like
ours, and efforts should be made to maximize its potential for high success in this setting.
