经口内镜粘膜下隧道肿瘤切除术切除食管固有肌层平滑肌瘤

摘要

起源于食管固有肌层的粘膜下肿瘤目前多采用胸腔镜下切除,随着内镜技术的发展,内镜粘膜下切除术(ESD)亦可用来切除源于固有肌层的粘膜下肿物,但是出现穿孔的风险大,穿孔以后内镜下闭合难度高.我们在开展ESD的基础上,借鉴经口内镜下括约肌切断术的经验,成功采用经口内镜粘膜下隧道肿物切除术切除起源于食管固有肌层的粘膜下肿物1例,相对于ESD操作,即使出现穿孔,亦可轻松闭合隧道口,有效防止气体以及消化液外漏.因此,经口内镜粘膜下隧道肿瘤切除术(STER)有望成为一种新的内镜下微创治疗方法切除源于食管固有肌层粘膜下肿物.%Tumors originating from the muscularis propria layer of esophagus are usually removed by thoracoscopic resection. With the introduction of new endoscopic therapeutic techniques, some of these tumors could be treated by endoscopic submucosal dissection (ESD). However, the above endoscopic methods are associated with a high risk of perforation and it is hard to close the perforation through the endoscopy. Recently we successfully resected a tumor originating from the muscularis propria layer of the esophagus by submucosal tunneling endoscopic resection (STER), which was based on peroral endoscopic myotomy (POEM) and ESD. Compared with ESD, STER is a safe, economic and less invasive treatment. Even when perforation happens, it is easier to close the tunnel with the endoscopic clips which can help stopping the leak of air and digestive fluids. In this case, we found STER wss an effective and safe endoscopic procedure to remove tumors originating from the muscularis propria layer in the esophagus.
