Outline of Final Research Achievements

Changes in body composition (body weight, body fat mass, skeletal muscle mass, serum branched-chain amino acids (BCAAs)) and nutritional status were investigated up to 1 month after discharge from the post-gastrectomy patients. The subjects of analysis were 11 (TG: 4 total gastrectomy, PG: 7 partial gastrectomy), and the average age was 69.9 years. There were no significant differences in body composition and serum BCAAs at 3 points (discharge, 1 week after discharge and 1 month after discharge) in both groups. The trunk muscle mass of the TG group continued to decrease gradually even one month after discharge, there was a difference from the change of the DG group (TG:-2.60 ± 0.94 vs DG:-0.83 ± 0.78 (p = 0.008)). Changes in trunk muscle mass in the DG group were correlated to serum BCAAs (r =-954, p = 0.046). The need for BCAA-rich nutrition intake to prevent skeletal muscle loss was suggested.

Academic Significance and Societal Importance of the Research Achievements

胃切除術後患者個々の経時的な回復状態，食事・栄養摂取状況の把握と疾病の病期や病態に応じた，嗜好性の高い食事・栄養補給ができることが重要である。そのためには，食事摂取に伴う症状の発現を抑え，自己の栄養状態に適った食べ方の主体的な栄養管理が必要である。今後，胃切除術後患者の食生活管理の実践化には，外来看護師，管理栄養士，医師が連携した指導体制づくりの必要性が生じている。
