Endoscopic treatment can be a curative option for small carcinoid tumors with an extremely low risk of metastasis. Since most carcinoid tumors are characterized by a specific growth pattern in the submucosal (SM) layer, specialized endoscopic techniques for deeper resection to achieve clear vertical margins are needed. The endoscopic submucosal dissection (ESD) method in the SM space is superior to conventional endoscopic mucosal resection. However, the standard ESD technique sometimes fails to provide complete deep SM dissection due to insufficient SM lifting. Here, to resolve this problem, we describe our initial experience with an endoscopic SM tunneling technique that is effective for treating rectal carcinoid tumors.
内镜治疗对于转移风险极低的小型类癌肿瘤是一种有治愈可能的选择。由于大多数类癌肿瘤的特征是在黏膜下层（SM）层具有特定的生长模式，因此需要专门的内镜技术进行更深层次的切除以获得清晰的垂直切缘。内镜黏膜下剥离术（ESD）在 SM 空间中的方法优于传统的内镜黏膜切除术。然而，由于 SM 提升不足，标准的 ESD 技术有时无法提供完全的深层 SM 解剖。在这里，为了解决这个问题，我们描述了我们在直肠类癌肿瘤治疗中使用内镜 SM 隧道技术的初步经验，该技术非常有效。
