About this trial

This is an interventional treatment trial for Lacrimal Duct Obstruction focused on measuring Primary,silicone tube,revision,mitomycin C,endoscopic DCR

Eligibility Criteria

18 Years - 90 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Adults (age > 18), ASAI-III, and were scheduled for primary or revision lacrimal pathway surgery due to recurrent or chronic watering eyes or conjunctival discharge.
  • Patients were excluded if they had previous nasolacrimal surgery, malignancy in the paranasal sinuses, nasal cavity, or lacrimal pathway, presaccal obstruction, pregnancy or lactation, or mental disability.

Exclusion Criteria:

  • Malignancy in the paranasal sinuses, nasal cavity, or lacrimal pathway, presaccal obstruction, pregnancy or lactation, or mental disability.

5. Study Description

Brief Summary
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.
