Protocol    The doctor prescribes Step 1 diet (clear liquid diet) as the first meal after surgery. Patients eat this diet for 2–3 meals. As the next meal, the doctor prescribes Step 2 diet (full liquid diet). Patients eat this diet for 2–3 meals. If the diet transition goes smoothly, the doctor prescribes Step 3 diet (soft diet). Patients eat this diet until discharge. The doctor prescribes hospital meal intake. Depending on the patient’s condition, the steps for consuming the diet could be adjusted. The dietitian surveys the dietary intake every day until discharge. If there is a meal-related side effect, it is reported to the doctor.
