Abstract

Background: A new device is described for secondary tracheoesophageal puncture (TEP). We hypothesize that the device can be used to create the puncture, size, and insert the voice prosthesis in antegrade fashion in a single procedure suitable for office-based use.

Methods: A measurement and insertion device (MAID) was designed with the hypothesis in mind and tested on 3 pigs while they were under general anesthesia.

Results: The procedure was easy and successful in all 3 animals. The MAID allowed measurement of tracheoesophageal wall thickness and antegrade insertion of voice prosthesis with a single device. Transnasal esophagoscopy (TNE) allowed visualization of markings on the MAID within the esophagus to facilitate sizing. Intraesophageal visualization using TNE also enabled accurate positioning, reduced risk of posterior esophageal wall injury, and practically eliminated false passage formation.

Conclusion: We believe the MAID can facilitate single-stage office-based secondary TEP in postlaryngectomy patients.

用于单阶段室内气管食管二次穿刺的新装置:动物实验。

背景:介绍了一种用于继发性气管食管穿刺(TEP)的新装置。我们假设该设备可用于创建穿孔，大小，并以顺行方式插入语音假体，这是一个适合办公室使用的单一程序。方法:设计一种测量插入装置(MAID)，在3头猪全身麻醉状态下进行试验。结果:3只动物手术简单、成功。MAID可以测量气管食管壁厚度，用单一装置顺行插入语音假体。经鼻食管镜检查(TNE)可以看到食管内MAID上的标记，以方便确定大小。使用TNE进行食管内显像也可以实现准确定位，降低食管后壁损伤的风险，并实际上消除了假通道的形成。结论:我们相信MAID可以促进喉切除术后患者的单期办公室继发性TEP。
