Feasibility and Safely of Oral Rehydration Therapy before Upper Gastrointestinal Endoscopic Submucosal Dissection

Figure 2

Time course for the PORT group and non-PORT group. In the PORT group, 500 mL of alginade water was administered up to 2 hours before ESD. In contrast, 500 mL of extracellular fluid infusion was administered in the non-PORT group before ESD. ESD: endoscopic submucosal dissection; PORT: preoperative oral rehydration therapy.
