Transcanalicular laser-assisted and external dacryocystorhinostomy anatomical and functional success in primary acquired nasolacrimal duct obstruction: systematic review and meta-analysis

Primary acquired nasolacrimal duct obstruction (PANDO) is a condition in which tear ducts are blocked, leading to epiphora and dacryocystitis. This systematic review and meta-analysis aimed to measure the ability of transcanalicular dacryocystorhinostomy (TC-DCR) as an alternative approach to PANDO...

Description
Summary:Primary acquired nasolacrimal duct obstruction (PANDO) is a condition in which tear ducts are blocked, leading to epiphora and dacryocystitis. This systematic review and meta-analysis aimed to measure the ability of transcanalicular dacryocystorhinostomy (TC-DCR) as an alternative approach to PANDO compared to traditional external dacryocystorhinostomy (EX-DCR). Our search included Embase, Medline, and the Cochrane Central Register of Controlled Trials (CENTRAL). We included only observational studies, randomized controlled trials (RCTs), and quasi-experimental studies that compared TC-DCR and EX-DCR. The outcomes measured were anatomical and functional success rates, intraoperative complications, postoperative complications, and surgical time. Statistically significant results were determined as a p value of less than 0.05; thus, a confidence interval of 95% was used. Dichotomous outcomes were reported via risk ratios (RR), whereas continuous outcomes were reported using standardized mean differences (SMD). There was a statistically significant difference in anatomical success (RR = 0.84, 95% CI 0.72-0.97; P = 0.02), favoring EX-DCR; functional success (RR = 0.87, 95% CI 0.78-0.97; P = 0.01), favoring EX-DCR; operative (OR) time (SMD = -2.42, 95% CI -2.92 - -1.91; P
