Abstract

Abstract : Introduction: Endoscopic dacryocystorhinostomy (eDCR) is the preferred approach for nasolacrimal duct obstruction, yet quality data on long‐term outcomes is lacking. Study Design: A retrospective study in a single, academic institution. Objective: To assess the 5‐ and 10‐year success rates of eDCR, and its associated risks. Patients and Methods: All eDCRs conducted at Kaplan Medical Center between the years 2002–2017 were included. For long‐term follow‐up analysis, two subgroups with a minimum of documented 5‐ and 10‐year follow‐up after surgery were defined. Surgical success was defined by both anatomical (observed patent lacrimal flow) and functional (symptomatic relief) success. Data was collected from the hospital's electronic medical records and was completed by phone interviews. Pre‐, intra‐, and postoperative variables were collected and stratified by multivariate analysis. Results: After exclusions, 321, 168, and 65 patients were included for immediate, 5‐ and 10‐year outcome analysis, respectively. Overall success rates were 92.5%, 86.3%, and 80%, respectively. The anatomical success rates were 93.8%, 89.9%, and 86.1%, respectively. Multivariate analysis revealed that older age ( P < .001, P = .001) previous smoking ( P = .043, P = .037), and postoperative complains of epiphora (even when a successful irrigation was observed, P < .001, P = .01) were all associated with eDCR failure 5 and 10 years following surgery. Male gender was also associated with eDCR failure (5 years, P = .045; 10 years, P = .063). Conclusions: Despite decreased rates over time, eDCR is beneficial for the majority of patients also at 10 years following surgery. Older age, smoking, postoperative epiphora, and male gender are related to long‐term failure and should be discussed with the patients before surgery.
