Summary
- If a patient undergoes gastrectomy, which is a kind of major abdominal operation, he/she
loses more than 5% of his/her body weight in 2 months after surgery. This point is one
of the criteria of 'risk of malnutrition' according to Nutrition Risk Screening (NRS
2002) and the patient who corresponds to this criterion needs nutritional support.
- According to Nutrition Risk Screening (NRS 2002), moderate malnutrition is defined as
the state that the patient orally intakes 25~50% of recommended requirements; severe
malnutrition is less than 25%.
- Meanwhile, when oral nutrition support was provided to patients after gastric cancer
surgery, the patients' average daily intake during the first three months was about a
half of the recommended requirements.
- Putting together the facts i) that the patient underwent major abdominal operation,
ii) that the weight loss rate exceeded 5% for two months, iii) that the average
daily intake of patients during the first three months was about half of the
recommended amount, the patients are eligible to be classified as a group who
require nutritional support according to NRS 2002.
Therefore, it is intended to verify the efficacy and safety of supplemental parenteral
nutrition by comparing Arm A, who are provided oral intake with supplemental parenteral
nutrition, Arm B, who are provided oral intake only after curative gastric cancer surgery.
