Summary
Endoscopic dacryocystorhinostomy (DCR) is effective, but diabetes, allergies, and prior eye surgery increase failure risk. Patients with these conditions should be aware of potential outcomes.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Endoscopic dacryocystorhinostomy (DCR) is a standard surgical treatment for nasolacrimal duct obstruction.
- The procedure boasts high success rates, typically exceeding 90%.
Purpose of the Study:
- To identify preoperative factors influencing the success of endoscopic DCR.
- To determine specific parameters associated with surgical failure.
Main Methods:
- Retrospective analysis of medical records from 165 patients (183 eyes) who underwent endoscopic DCR.
- Data collection focused on surgical outcomes and reasons for failure between January 2010 and August 2016.
Main Results:
- The overall success rate for endoscopic DCR was 94.7%.
- Significant predictors of surgical failure included diabetes mellitus (P=0.037), medication allergies (P=0.034), and previous ocular surgery (P=0.043).
- No correlation was found between failure rates and facial trauma, prior nasal/lacrimal surgery, or stent usage.
Conclusions:
- Endoscopic DCR remains a safe and effective procedure for nasolacrimal duct obstruction.
- Diabetes mellitus, allergies, and prior ocular surgery are identified as risk factors for increased surgical failure rates.
- Patients with these risk factors should be counseled regarding potentially higher failure rates.

1.0K
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

1.2K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
