Outcomes in pediatric powered endoscopic dacryocystorhinostomy: a single-center experience

Abstract

ABSTRACTPurpose: The purpose of the article is to report the outcomes of powered endoscopic dacryocystorhinostomy (PEnDCR) in pediatric patients.Methods: A single-center, single surgeon, retrospective, interventional, non-comparative case series was performed on all pediatric patients who underwent PEnDCR between July 2014 and July 2017. Patients with associated congenital anomalies like single punctum agenesis or lacrimal fistula were excluded. Surgery was performed as per standard protocols published earlier. Data collected include demographics, clinical presentations, past interventions, indications for the surgery, intraoperative and postoperative complications, postoperative ostium characteristics, and anatomical and functional success.Results: Ninety-one eyes of 83 children underwent PEnDCR during the study period. Mean age was 8.32 years and epiphora was the most common presentation (81%, 74/91). The most common indication for PEnDCR was persistent congenital nasolacrimal duct obstruction refractory to earlier interventions of probing or intubation. Postoperative ostium assessment at 4 weeks showed a well-healed ostium with a dynamic internal common opening in 86.8% of the eyes. Edge granulomas of the ostium were the most common abnormal finding in the postoperative period (9.8%, 9/91) and all except one could be managed conservatively. At 6 months follow-up, five eyes showed anatomical failure and additional two eyes showeXd functional failure. Two of anatomical failure group and one of functional failure underwent a second intervention. The final anatomical and functional success were noted in 96.7% (88/91) and 95.6% (87/91), respectively.Conclusions: This study shows that PEnDCR is a safe surgery for pediatric populations with a high success rate of beyond 95%.
