Abstract
Backgroud/Aims: Endoscopic ultrasonography (EUS) has been used in assessing the depth of cancer invasion of the stomach. The aim of this study was to compare the factors which were likely to affect the diagnostic accuracy of EUS for the depth of invasion in early gastric cancer (EGC).
Methods:
Seventy eight EGC patients were pre-operatively examined by EUS. The depth of invasion by EUS was compared with the histopathologic finding of the resected specimen. The diagnostic accuracy of EUS was analyzed according to the factors which were likely to affect the accuracy.
Results:
The diagnostic accuracy of EUS for the depth of invasion was 78% (46/49) in mucosal cancer, 68.4% (13/19) in submucosal cancer (p<0.05). Overall diagnostic accuracy of EUS in EGC was 75.6%. The diagnostic accuracy of the flat submucosal cancer was 55.6% and was significantly lower than other types of mucosal or submucosal cancers in endoscopic morphology (p<0.05).
Conclusions:
The depth of invasion per se with respective endoscopic findings affected the diagnostic accuracy of EUS for the depth of invasion in EGC. Other factors did not affect the diagnostic accuracy of EUS for the depth of invasion in EGC. (Korean J Gastrointest Endosc 2004;29:6⁣12)
