Practical principles of differential diagnose between benign and not benign gastric lesions (type, borders, infiltration estimation)

Endoscopic diagnosis of EGC involves detection and then characterization. This two-step process to determine the requirements for curative ESD. Because endoscopic submucosal dissection (ESD) of gastric cancer can only be curative if the cancer is detected at an early stage and a precise preoperative diagnosis is made. Preoperative assessment for ESD involves determining: (i) histological type; (ii) size; (iii) depth of invasion; (iv) presence or absence of associated ulceration; and (v) horizontal extent of the cancer.
