Simulation of KTP Laser–Based Zenker Diverticulotomy with a Porcine Model and Laryngeal Dissection Station:
[摘要] Zenker’s diverticulum is a rare cause of progressive dysphagia that is treated surgically. Potassium titanyl phosphate (KTP) laser–based diverticulotomy is one effective treatment. Developing a simulation model is helpful for rare conditions. Pigs have a natural hypopharyngeal pouch similar to a diverticulum. We present a model for performing rigid endoscopic KTP laser diverticulotomy in a porcine model with a laryngeal dissection station. Eleven pigs were examined to confirm presence of the hypopharyngeal pouch. A specimen was mounted on the modified laryngeal dissection station, and a KTP laser–based diverticulotomy was performed. Novel aspects include use of the laryngeal dissection station and application of the model for simulating rigid endoscopic KTP laser diverticulotomy. This model allows trainees to practice equipment setup, positioning of the laryngoscope to isolate the cricopharyngeal bar, tissue handling, laser safety techniques, and use of the KTP laser through the laryngoscope under microscopic visualization.
