The diagram shows the implications of the layer of origin that is identified on EUS. Whereas tumors that arise from the muscularis mucosae can be resected endoluminally, if appropriately indicated — using endoscopic submucosal dissection (ESD), for example — tumors that arise from the muscularis propria, particularly when they bulge outward, have to be removed using other techniques such as a tunnel resection in the esophagus.
