A Prospective Longitudinal Study to Evaluate the Outcomes of Success of Endoscopic DCR in Pediatric Age Group.

Children with nasolacrimal duct obstruction (NLDO) have different therapeutic approach from that used in adults. Dacryocystorhinostomy (DCR) is the most common procedure in adults but it is less frequently carried out in children, indicated in children which are refractory to probing. The objective of the study is to report a series of 30 cases of paediatric epiphora who underwent endoscopic endonasal dacryocystorhinostomy surgery, for primary obstruction of nasolacrimal duct and results, outcomes of success are evaluated. This is a prospective and non-comparative review of 30 cases of epiphora aged between 3 and 9 years from April 2018 to March 2019. The main outcome measures assessed were determined by the resolution of symptoms and the patency of the lacrimal anatomy confirmed by syringing or irrigating the nasolacrimal duct. Secondary outcomes included the presence of such complications as bleeding, scarring, and/or persistent epiphora and infection. In our study 30 patients underwent unilateral DCR surgery in NLDO. Out of 30 patients males were 17 and females were 13. The overall success rate of endoscopic DCR was 90%, and failed cases were mainly due to pre-saccal obstruction. No major complications were reported, minor complications occurred in about 60% of cases. Analysis of the results indicated that EDCR was safe and an effective therapeutic approach for treating nasolacrimal duct obstruction in pediatric age group patients having NLDO. It's considered as an alternative procedure to external dacryocystorhinostomy after a failed conservative treatment.
