Endoscopic dacryocystorhinostomy (EN-DCR) is an effective procedure when treating saccal and postsaccal obstructions of the nasolacrimal pathway. The benefit of silicone tubing after DCR is still controversial. We conducted a prospective, randomized study in order to evaluate 1) the necessity of bicanalicular silicone tubes after primary EN-DCR, 2) efficacy of the perioperative Mitomycin C for the prevention of adheesion and re-stenosis of rhinostomy site in revision EN-DCR, 3) the subjective symptoms and QoL changes before and after DCR-operation.

Further study details as provided by Juha Seppa, Kuopio University Hospital:

Primary Outcome Measures:
  • The success rate after primary DCR with and without silicone tubes. The success rate after revisio DCR with and without Mitomycin C. [ Time Frame: 5 years ]

Secondary Outcome Measures:
  • The EN-DCR operation influence on the patients subjective symptoms and QoL before and after operation. [ Time Frame: 5 years ]

Estimated Enrollment: 80
Study Start Date: September 2004
Estimated Study Completion Date: December 2016
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
surgical Procedure: DCR

The patients were randomized into the two study groups, either with or without the insertion of a bicanalicular silicone tube after primary DCR.

In revision group patients were randomized into the two groups,ether with or without application of mitomycin "C" after DCR
