The clinical study of endoscopic dacryocystorhinostomy by suture / 中国基层医药

ABSTRACT

Objective To investigate the clinical value of endoscopic transnasal dacryocystorhinostomy ( ET-DCR) by suture techniques.Methods 85 patients of 98 eyes with chronic dacryocystifis were randomly divided into the two groupscontrol group ( without suture) and observation group ( by suture) .All cases were followed up for more than 12 months.The cure rates and occurrence of granulation tissue were compared between the two groups. Results The cure rate of the observation group ( 96.00%, 48/50 ) was higher than that in the control group (81.25%,39/48) (χ2 =5.35,P<0.05). During process of following up,the occurrence of granulation tissue at the ostium margins accounted for 14.00%(7/50) in the observation group and 31.25%(15/48) in the control group (χ2 =4.19,P<0.05).Conclusion ET-DCR by suture techniques reduces the formation of granulation tissue and improves the cure rate.Especially, ET-DCR by suture techniques for the small lacrimal sac of patients may have special advantages.
