Efficacy study of endoscopic dacryocystorhinostomy with decompression of lacrimal sac

Abstract

Objective Study and analyze the clinical effect of endoscopic dacryocystorhinostomy with decompression of lacrimal sac. Methods Prospective randomized controlled trail. 269 patients (302 eyes) with chronic dacryocystitis were diagnosed in Aier eye hospital of Wuhan university from February 2018 to September 2023, and all patients were underwent endoscopic dacryocystorhinostomy. According to the principle of double-blind random sampling, they were divided into two groups before surgery. Group A was treated with decompression of lacrimal sac during the operation, while the lacrimal sac decompression was not performed during operation in group B. Regular follow-up to 6mo postoperative was carried out to count the postoperative efficacy of two groups of patients. Results Five patients (6 eyes) lost to follow-up were removed, a total of 264 patients (296 eyes) were included in the comparative analysis in this study. 136 cases (151 eyes) in the group A were included in the comparative analysis, the cure rate was 82.78%, the improvement rate was 13.25%, the effective rate was 96.03%, and the inefficiency was 3.97%. While in group B, the cure rate of 128 cases (145 eyes) was 62.76%, the improvement rate was 26.90%, the effective rate was 89.66%, and the ineffective rate was 10.34%. The difference in efficacy between the two groups was statistically significant (χ2 = 15.147, P = 0.000). Conclusion Dacryocyst decompression performed during endoscopic dacryocystorhinostomy can improve the efficacy of surgery and reduce the occurrence of complications.
