“…Dacryocystorhinostomy (DCR) creates a low-pressure system by diverting tear flow through the lacrimal bone and an artificial opening. Toti first described external DCR in 1904, and Caldwell used an endonasal technique in 1893 that West modified in 1914 [1][2][3] .…”

Objective: To analyze the efficacy of endoscopic dacryocystorhinostomy (DCR) with marsupialization of the lacrimal sac compared with other techniques of endoscopic dacryocystorhinostomy. Material and methods: Clinical chart review. Patients with lacrimal sac pathologies and endoscopic DCR with or without marsupialization of the lacrimal sac were included from 2011 to 2015. The outcome measurements were absence of ocular symptoms and permeability of the lacrimal sac. Results: A total of 24 patients were evaluated, 17 women and 7 men, average age was 47 years. Seven patients underwent DCR with marsupialization, 17 patients underwent other endoscopic techniques. Average follow-up was 18 months. The efficacy (absence of symptoms and permeability of the lacrimal sac) of the DCR technique with marsupialization was 71%, without significant difference compared to other techniques (p = 0.686). Conclusion: Similar results were found in the different types of endoscopic DCR techniques. More studies are needed to corroborate our results.
