阑尾的浅表肿瘤大多是内窥镜切除的禁区，因为完全切除的技术挑战和穿孔的风险，因为几何上困难的解剖结构。1例72岁男性患者行结肠镜检查，诊断为颗粒状横向扩散性肿瘤从盲肠侵犯阑尾。肿瘤有不规则的毛细血管（2B型，JNET分类）和管状凹陷模式（IIIL型，Kudo分类）。将结肠镜的尖端推到阑尾口上，可见一个20 mm的肿瘤扩散到阑尾的一半区域。
Superficial tumors at the appendix are mostly off limits for endoscopic resection due to the technical challenge of a complete resection and risk of perforation because of the geometrically difficult anatomy. 1A 72-year-old man underwent colonoscopy with the diagnosis of a granular laterally spreading tumor invading the appendix from the cecum. The tumor had irregular capillary (type 2B, JNET classification) and tubular pit patterns (type IIIL, Kudo classification). The tip of the colonoscope was pushed onto the appendiceal orifice, and a 20-mm tumor spreading into the appendix for half of its area was visualized.
