Efficacy Study of a Low Volume of Water Intake and Mosapride for Endoscopy in Patients With Subtotal Gastrectomy

Efficacy of a Low Volume of Water Intake and Mosapride for Endoscopy Preparation in Gastric Cancer Patients With Subtotal Gastrectomy: A Randomized Controlled Trial

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.

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.
