Laboratory Medicine Summary

Although no specific testing is indicated after tracheoesophageal puncture (TEP), visualization of the neopharynx, esophagus and trachea may help in determining the cause of problems, such as during leakage or stenosis. Tests include esophagoscopy (with or without insufflation to determine the quality of seal), bronchoscopy, or swallow study. [4] However, a swallow study may be contraindicated in the presence of a suspected TEP leak, due to the likelihood of aspiration of contrast.
