A 68‐YEAR‐OLD MAN was diagnosed with early esophageal cancer after detection of a lesion measuring 15 mm in diameter. The lesion was located close to the postendoscopic submucosal dissection (ESD) scar (Fig. 1a). As a conventional scope could not approach the lesion because of postoperative stricture as a result of hypopharyngeal cancer (Fig. 1b), a thin endoscope was used. Endoscopic resection can be carried out after dilatation for the stricture, but this entails risk of perforation. EG-L580NW7 (Fujifilm, Tokyo, Japan) is a thin-endoscope; length of the distal end and instrument channel are 5.9 and 2.4 mm, respectively. Souten and Raicho (Kaneka Medics, Tokyo, Japan; Fig. 1c,d) are the available cutting and hemostatic devices. The entire procedure is presented in Video S1. Handmade attachment prepared with transparent tape was used. Local injection (needle: 25 G, 3 mm; TOP, Tokyo, Japan) was

薄型内窥镜黏膜下剥离术治疗早期食管癌术后狭窄

一名 68 岁的男性在检测到直径为 15 毫米的病变后被诊断出患有早期食管癌。病变位于靠近内窥镜黏膜下剥离术 (ESD) 瘢痕处（图 1a）。由于下咽癌术后狭窄（图 1b），传统内窥镜无法接近病灶，因此使用了薄型内窥镜。狭窄处扩张后可进行内镜下切除，但存在穿孔风险。EG-L580NW7（富士胶片，​​日本东京）是一款超薄内窥镜；远端和器械通道的长度分别为 5.9 和 2.4 毫米。Souten 和 Raicho（Kaneka Medics，日本东京；图 1c、d）是可用的切割和止血装置。整个过程在视频 S1 中介绍。使用用透明胶带制作的手工附件。
