We evaluate that a 500mL of water intake and mosapride will effectively reduce food residue in remnant stomach for patients who had undergone subtotal gastrectomy due to gastric cancer. We plan to compare this method with routine midnight fasting method for endoscopy in patients with subtotal gastrectomy.
A low volume of water intake and mosapride will effectively reduce food residue in remnant stomach for patients who had undergone subtotal gastrectomy due to gastric cancer.
