Endoscopic Mucosal Resection (EMR) of Early Gastric Cancer

Abstract

We conducted this study to clarify the effectiveness of aspiration endoscopic mucosal resection (EMR) using a cap-fitted scope for early gastric cancer in the C and M regions of the stomach. E M R was performed in 1 1 1 early gastric cancer patients with 123 lesions in the C and M regions. The patients were divided into three groups. The EMR-1 CS group consisted of patients who had undergone E M R with a one-channeled scope, the EMR-2CS group those who had received E M R in which a two-channeled scope was utilized. The E M R C group consisted of patients who had undergone aspiration E M R with a cap-fitted scope.The rate of complete resection improved to a statistically significant degree in the E M R C group in comparison with that in the E M R -1 C S group. In type Ilc, a statistically significant improvement was achieved in the E M R C group in comparison with the EMR-2CS group. In the M region or in lesions 1 0 mm or less in diameter, the rate of complete resection improved in the E M R C group as compared with that in the EMR-2CS group. Our results suggest that E M R C is useful for lesions of early gastric cancer in the C and M regions. (Dig Endosc 1998; 1 0 : 3 1 -3 6 )

Treatment of Esophageal and Gastric Tumors

“…In our own group's experience, EMRC is easy to perform in this part of stomach, since the cap on the tip makes it easier to approach the target mucosa in an en-face direction. This view is also supported in the report by Chonan et al [30].…”
