食管环周病变较少见,内镜下治疗相对困难。内镜下切除术(ER)可用于治疗短段环周病变。内镜黏膜下剥离术(ESD)可完整切除病变,适用于范围较大的病变,但对于长环周病变的切除仍较为困难。内镜下隧道式黏膜剥离术(ESTD)可提高食管环周病变的切除速度,且病变长度不再成为食管黏膜病变内镜下治疗的限制。环周黏膜病变切除后狭窄不可避免,推荐术后预防性应用激素、球囊扩张或支架置入,可能需要联合多种治疗手段。
Esophageal lesions are less common, endoscopic treatment is relatively difficult. Endoscopic resection (ER) can be used to treat short-term circumferential lesions. Endoscopic submucosal dissection (ESD) can be completely removed lesions for a wide range of lesions, but for the removal of long circumferential lesions is still more difficult. Endoscopic tunnel mucosal dissection (ESTD) can improve the esophageal peripheral lesions removal rate, and the lesion length is no longer the limit of endoscopic treatment of esophageal mucosal lesions. Cervical mucosal lesions resection stenosis is inevitable, recommended postoperative prophylactic use of hormones, balloon dilatation or stent placement, may require a combination of multiple treatments.
