Alternative technique in secondary tracheoesophageal puncture using flexible endoscope and overtube in patients with difficult post-laryngectomy abnormalities
This study presents an improved method of secondary tracheoesophageal prosthesis insertion using a flexible endoscope in association with a plastic pliable overtube to keep the virtual esophageal lumen open. By this method, the puncture can be performed easily and safely with the avoidance of unexpected lesions.
Results:
From 2005 to 2015, 12 (16,9%) out of 71 patientswho underwent secondaryvoice prosthesis placement at our institution required this alternative technique due to anatomical alterations that hindered the execution of the procedure following the standard technique.
