Submucosal endoscopy with a mucosal flap (SEMF) safety valve technique is a global concept in which the submucosa is a free working space for endoscopic interventions. A purposefully created intramural space provides an endoscopic access route to the deeper layers and into the extraluminal cavities. The mucosa overlying the intramural space is protective, reducing contamination during natural orifice transluminal endoscopic surgery (NOTES) procedures and providing a sealant flap to repair the entry point and the submucosal space. In addition to NOTES, SEMF enables endoscopic achalasia myotomy, histologic analysis of the muscularis propria, and submucosal tumor removal.
带黏膜瓣的黏膜下内镜（SEMF）安全阀技术是一个全球性的概念，其中黏膜下层是内镜干预的自由操作空间。有目的地创建的壁内空间提供了一条通向更深层和腔外腔隙的内镜进入途径。覆盖壁内空间的黏膜具有保护作用，可减少经自然腔道内镜手术（NOTES）过程中的污染，并提供一个密封瓣来修复进入点和黏膜下层空间。除NOTES外，SEMF还可进行内镜下贲门失弛缓症肌切开术、固有肌层的组织学分析以及黏膜下肿瘤切除。
