Abstract
Objective: Conduct the first prospective randomized controlled study investigating the safety and efficacy of endocanalicular high pressure 5-mm balloon catheter endoscopic dacryocystorhinostomy (DCR) in adult patients with acquired complete nasolacrimal obstruction.
Method: This prospective randomized controlled study was conducted between 2004 and 2009 including 70 procedures of endoscopic dacryocystorhinostomy. They were prospectively equally randomized into 2 groups; endocanalicular high-pressure 5-mm balloon catheter endoscopic DCR (group I) and conventional endoscopic DCR (group II). Regular follow up settings were done to document the patient’s subjective improvement, to judge ostium patency on irrigation, and to record any complications. Statistical analysis was done using SPSS for Windows. The primary end point was determined to be the success of the surgery as defined by the subjective disappearance of symptoms.
Results: Both groups demonstrated a success rate of 91.4%. There was a shorter mean operative time (25.7 minutes) in the endocanalicular balloon catheter endoscopic DCR group.
Conclusion: The endocanalicular balloon catheter endoscopic DCR shares the benefits and success rate of conventional endoscopic DCR. In addition, it is simpler, requires less manipulation, consumes a shorter operative time, has a better safety profile, and can be totally utilized under local anesthesia with minimal sedation.
