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.
A measurement and insertion device (MAID) was designed with the hypothesis in mind and tested on 3 pigs while they were under general anesthesia.
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.
We believe the MAID can facilitate single-stage office-based secondary TEP in postlaryngectomy patients.
描述了一种用于二次气管食管穿刺（TEP）的新装置。我们假设该装置可用于在适合门诊使用的单一手术中顺行方式进行穿刺、确定尺寸并插入语音假体。
设计了一种测量和插入装置（MAID），并在3头处于全身麻醉状态的猪身上进行了测试。
该手术在所有3只动物中均简便且成功。MAID允许使用单一装置测量气管食管壁厚度并顺行插入语音假体。经鼻食管镜检查（TNE）可观察到食管内MAID上的标记，以利于确定尺寸。使用TNE进行食管内可视化还能实现精确定位，降低食管后壁损伤风险，并几乎消除假道形成。
我们认为MAID可促进喉切除术后患者在门诊进行单阶段二次TEP。
