Recently, several transoral approaches for minimally invasive surgery have been developed for oropharyngeal cancer. However, all approaches have certain disadvantages. Therefore, we built and examined new surgical environments for improving the situation.
Endoscopic transoral resection using a pharyngeal retractor or distending laryngoscope, rigid videoendoscope, and laparoscopic surgical instruments was performed in 17 patients with oropharyngeal squamous cell carcinoma. Postoperative results regarding oncology and function as well as complications were documented.
The 2-year relapse-free survival rate was 100%. Postoperative swallowing and speech function were satisfactory: 94.1% of cases scored ≤1 on the functional outcome swallowing scale (FOSS) and ≤1 on the communication score. Further, no perioperative mortality occurred.
The improved surgical environment made it possible to perform a safe and reliable en bloc resection with a wide field of view and sufficient working space. Our system can be useful, although further studies on additional cases are required.
最近，已经开发出几种用于口咽癌的微创经口手术入路。然而，所有方法都有一定的缺点。因此，我们构建并检查了新的手术环境，以改善这种情况。
对 17 例口咽鳞状细胞癌患者使用咽牵开器或扩喉喉镜、硬性视频内镜和腹腔镜手术器械进行经口内镜切除。记录术后肿瘤学和功能以及并发症的结果。
2 年无复发生存率为 100%。术后吞咽和言语功能令人满意：94.1%的病例在功能结局吞咽量表（FOSS）上评分为≤1，在交流评分上评分为≤1。此外，无围手术期死亡。
改进的手术环境使得能够进行安全可靠的整块切除，并具有广泛的视野和足够的工作空间。我们的系统可能有用，但需要进一步研究更多病例。
