Comparison of surgical outcome of endoscopic DCR using gouge or drill with or without stent

The aim of the study was to evaluate the longterm results of endoscopic endonasal dacryocystorhinostomy in the management of epiphora due to nasolacrimal duct obstruction.The prospective study included 30 patients of all age and either sex with features of dacrocystitis. Patients were randomly distributed for one of the following surgeries - Dacryocysto-rhinostomy using Stent and Powered instruments (STPI) / Dacryocysto-rhinostomy using Stents and Gouge (STGO) / Dacryocysto-rhinostomy using Powered instruments (NSPI) / Dacryocysto-rhinostomy using only Gouge (NSGO). Follow up till 365 days was done and data on outcome, recurrence and complications were collected.: Success rate of all the procedures were 100 % at Day 3 and Day 7. On Day 30, success rate of all the procedures except NSGO were 100 %. At day 90 and 180, success rates were NSGO (85.7%); NSPI (100%); STGO (100%); STPI (85.7%). At day 365, success rates were NSGO (57.1%); NSPI (100%); STGO (100%); STPI (71.4%). The difference was not statistically significant (p <0.05). The results indicate that the success rate of all the four modalities are comparable. : Endoscopic DCR is a safe day-care procedure done which can be done under local anaesthesia with excellent results. Its efficacy ranges from 85.7-100% on Day 90 and 180; and 57.1-100% on Day 365. Success rate of all four procedures are same. In view of high success rate and low complications with all four procedures (NSGO; NSPI; STGO; STPI), endoscopic DCR using gouge or drill with or without stent were recommended.
