Does stenting improve the surgical outcome of Endoscopic Dacryocystorhinostomy? A prospective randomized study

Abstract

Introduction: The objective of this study was to compare the surgical outcome of endoscopic dacyrocystorhinostomy with or without stenting. It was a prospective, randomized study conducted from October 2011 to September 2013. Ganesh Man Singh Memorial Academy for ENT-Head and Neck Studies ,Tribhuvan University Teaching Hospital, Maharajgunj Medical Campus, Institute of Medicine, Kathmandu, Nepal.

Methods: Patients aged 15 years and above of all genders with primary acquired nasolacrimal duct obstruction (PANDO) were included in the study. Forty patients were randomly allocated into two groups, 20 each in Endoscopic Dacyrocystorhinostomy with stenting (EwS) and Endoscopic Dacyrocystorhinostomy without stenting (EoS). Post-operative assessment was done at 8 weeks. In the subjective assessment using with 5-point Likert Scale of degree of epiphora, a score of 1, 2 or 3 was considered a success. Objective assessment with syringing and endoscopic evaluation of patency of rhinostome considered patent and partly patent lacrimal system on syringing and patent rhinostome as success.

Results: Both the subjective and objectivesuccess rate was 95% in EwS and 90% in EoS.However, there was no significant statistical difference between the two groups (p value =1.00).

Conclusion: The success rate of EwS was comparable to that of EoS with no added benefit in our study. In addition, EoS avoided the complications associated with stenting. So, we recommend EoS for PANDO.
