  • Title: External dacryocystorhinostomy outcomes in patients with a history of dacryocystitis.
    Author: Lefebvre DR, Dhar S, Lee I, Allard F, Freitag SK.
    Journal: Digit J Ophthalmol; 2015; 21(3):1-22. PubMed ID: 27330467.
    Abstract:
    PURPOSE: To investigate nonidiopathic causes of external dacryocystorhinostomy (DCR) failure. METHODS: The medical records of all patients with acute or chronic dacryocystitis who underwent external dacryocystorhinostomy performed by the senior author over a 5-year period were retrospectively reviewed, with attention to microbiology, pathology, and associated medical and history. RESULTS: A total of 52 lacrimal systems of 49 patients were included, with a minimum follow-up of 2 months (average, 15.5 months). Surgical success was achieved in 42 systems (87%). Of 7 failures, 6 had a condition potentially associated with an increased risk of failure, including MRSA infection, Gram-negative infection, rhinosinusitis, lymphoma, inflammatory bowel disease, and early loss of lacrimal stents. CONCLUSIONS: External DCR is a successful procedure for the treatment of nasolacrimal obstruction associated with dacryocystitis. Various factors may affect surgical success, and awareness of these factors may enable better patient counseling and surgical planning.
