Three‐dimensional endoscopic ultrasonography for the assessment of early gastric carcinoma invasion: could it provide diagnostic innovations?
BACKGROUND: This study aimed to evaluate a three‐dimensional endoscopic ultrasonographic (3‐D EUS) system in the assessment of the tumor invasion depth of early gastric carcinoma. METHODS: Sixty‐nine macroscopically early cancer lesions in 67 patients were recruited in an _in vivo_ study. The surgically resected gastric specimens of 30 of them were re‐examined in an _ex vivo_ study. An Olympus 3‐D ... Read more
