Clinical comparative study of endoscopic dacryocystorhinostomy and lacrimal duct retrograde tube insertion in the treatment of nasolacrimal duct obstruction
Objective To compare the clinical effect of endoscopic dacryocystorhinostomy and lacrimal duct retrograde tube insertion in the treatment of nasolacrimal duct obstruction(NLDO).Methods 50 patients with nasolacrimal duct obstruction were divided into group A(single number date,25 cases)and group B(even number date,25 cases)according to the odd-even number of days of treatment.Group A underwent endoscopic retrograde lacrimal duct insertion,and group B underwent endoscopic dacryocystorhinostomy.The operation related indexes,complication rate and recurrence rate were compared between the two groups.Results The operation time and hospital stay of group A were(29.25±3.18)min and(0.85±0.23)d,which were significantly shorter than(51.74±3.26)min and(4.47±1.26)d of group B;group A had less blood loss of(5.03±1.06)ml than(46.45±11.12)ml in group B(P<0.05).The incidence of complications in group A(4.00%)was lower than that in group B(24.00%),but 1-year postoperative recurrence rate(28.00%)was higher than that in group B(4.00%)(P<0.05).Conclusion Endoscopic lacrimal duct retrograde tube insertion for nasolacrimal duct obstruction has the advantages of shorter operation time,easier operation,and less bleeding than dacryocystorhinostomy,whereas endoscopic acryocystorhinostomy is more favorable to the prevention of postoperative recurrence than lacrimal duct retrograde tube insertion.
