1-3 tracheal resection
Generated Jan 16, 2015 by raymond.allen555


The age of the patient did not seem to directly contribute to the mortality rate of this procedure.

The highest incidence of fatal outcomes is when the resection was 4 cm in length. However, larger areas of resection, did not appear to have a higher risk of death.

The P Value is greater than 0.05, meaning there is no statistical significance regarding death respective to prior surgery or not prior surgery.
