Resumo

Purpose: To evaluate the effect of stents on the success of endoscopic dacryocystorhinostomy (DCR-EN) for treating primary acquired nasolacrimal duct obstruction (NLDO). Method: A systematic review of randomized clinical trials of DCR-EN for NLDO comparing outcomes of surgeries performed with and without the use of bicanalicular stents and the complications associated with each procedure. Two authors independently searched six databases (Scopus, PubMed, EMBASE, Google Scholar, Cochrane Central Register of Controlled Trials, and Web of Science) up to May 2019. Statistical analysis and meta-analysis were performed using RevMan 5.3 software provided by the Cochrane Collaboration. Results: Twelve studies involving 997 surgeries were included in this systematic review. The meta-analysis using a fixed-effects model showed a 94% success rate with stents versus 90.6% without stent. Although stent use favors greater success of DCR-EN, the confidence interval (CI) was wide and very close to nullity line (1.01), decreasing the strength of the recommendation for stent (odds ratio: 1.62, 95% CI: 1.01–2.59, I2 = 0%). Meta-analysis of the adverse effects was not possible. A descriptive analysis was performed of the general complications related to the stents. Conclusions: There is evidence that the use of bicanalicular stents slightly improves the success rate of DCR-EN, but the quality of evidence is low. Future prospective, randomized trials enrolling larger sample sizes may provide stronger evidence to determine whether the stent use influences the success of primary acquired DCR-EN.
