? Patients with gastric adenoma or adenocarcinoma that were taken gastric submucosal dissection in our hospital
- the indication of endoscopic submucosal dissection
: absolute indication
(1) well-differentiated elevated cancers less than 2 cm in diameter
(2) small (< 1 cm) depressed lesions without ulceration.
These lesions must also be moderately or well-differentiated cancers confined to the mucosa, and have no lymphatic or vascular involvement
: expanded indication
(1) differentiated mucosal cancer without ulcer findings, irrespective of tumor size(including the tumor that is larger than 2cm)
(2) differentiated mucosal cancer with an ulcer = 3 cm in diameter
(3) minimal (= 500 µm from the muscularis mucosa) submucosal invasive
differentiated cancer = 3 cm in size
(4) undifferentiated intramucosal cancers without ulcer findings : 20 mm in size
? early gastric cancer with lymphatic invasion or over indication of endoscopic submucosal dissection
? patients who refused to sign the consent
? pregnancy
