A proposed grading system for post-intubation tracheal stenosis

Area of Science:

• Pulmonology
• Surgical Critical Care

Background:

• Post-intubation tracheal stenosis is a significant complication of endotracheal intubation.
• Existing classification systems lack management guidance.
• There is a need for a system to guide surgical intervention decisions.

Purpose of the Study:

• To introduce a novel classification system for post-intubation tracheal stenosis.
• To evaluate the system's efficacy in identifying patients requiring surgical intervention.

Main Methods:

• Developed a classification system based on stenosis size, type, and clinical presentation.
• Graded stenosis using clinical examination and rigid bronchoscopy.
• Performed ROC curve analysis to establish an optimal cut-off point.

Main Results:

• Studied 60 patients; 49 underwent resection and anastomosis.
• The developed scoring system showed a sensitivity of 89% and specificity of 42% with a cut-off of 8.5.
• A strong agreement (kappa = 0.78) was found between the score and surgeon's judgment, with scores > 8.5 significantly predicting surgical need (P=0.007).

Conclusions:

• A new scoring system for post-intubation and tracheostomy tracheal stenosis has been developed and prospectively evaluated.
• This system integrates key diagnostic and treatment factors.
• The system shows potential for standardizing treatment interventions and facilitating comparative studies.
