Research Article: Successful outcomes of pediatric dacryocystorhinostomy with adjunctive 5-fluorouracil
Abstract:
To determine whether nasal intramucosal 5-fluorouracil (5-FU) injection improves outcomes after external dacryocystorhinostomy (DCR) in pediatric patients with nasolacrimal duct obstruction (NLDO).
Multi-center retrospective non-comparative case series review of all DCR cases with intra-operative 5- FU injection performed between 2014 and 2023 on all patients age < 18 years. Each case was reviewed to determine if the patients had epiphora recurrence following surgery with 5-FU injection.
Sixteen pediatric patients with NLDO (19 eyes) underwent DCR and nasal intramucosal injections of 5-FU intra-operatively. One had a lost stent. Ten (53%) eyes were in patients with craniofacial syndromes. In all patients with the use of 5-FU there was no recurrence of tearing. Eight of the patients (42%) had already had at least one or two failed stents prior in which recurrence had occurred. There were no post-operative complications.
Adjuvant intramucosal 5-FU demonstrated a 100% success rate of epiphora not recurring following pediatric DCR without any complications in this small sample size, particularly in patients with increased risk of recurrence.
Introduction:
Most cases of pediatric nasolacrimal duct obstruction (NLDO) are due to congenitally incomplete canalization of the nasolacrimal duct ( 1 , 2 ). Obstruction of the nasolacrimal duct can cause excessive tearing and possibly dacryocystitis. The reported incidence of pediatric NLDO ranges from 5% to 20% ( 2 , 3 ). Though most cases of NLDO resolve with observation and lacrimal sac massage, persistent cases may require surgical intervention ( 4 ). First line surgical treatment of congenital NLDO is nasolacrimal duct…
