The Comparison of Sizes Measured by Esophagogastroduodenoscopy and Endoscopic Ultrasonography in Small Submucosal Tumors

Endoscopic ultrsonography (EUS) can provide detailed information about submucosal tumors such as size, echo pattern, wall of origin and relation to adjacent organs. However, EUS is not a cost effectiveness and time-consuming procedure and many patients experience discomfort during the procedure. We tried to verify the usefulness of Esophagogastroduodenoscopy (EGD) in the measurement of submucosal tumor size in comparison with EUS.
We compare the size of small submucosal tumors from 68 patients measured by EGD and EUS at Konyang University Hospital from year 2000 to 2003.
Most of submucosal tumors were located in muscularis propria layer. The size of submucosal tumor measured by gastroscopy correlated well with the size by EUS (r=0.91). Submucosal tumor measured by EGD was slightly larger than EUS measurement (p=0.008).
The size of submucosal tumors measured by EGD was slightly larger than that by EUS due to covering mucosa, but both sizes were linearly correlated. So we think that gastroscopy plays as one strategy for the surveillance or follow-up procedure of small sized submucosal tumors which do not exhibit the suspicion of malignant potential.
