Outline of Final Research Achievements

This multicenter retrospective study comprised 248 patients with severe obesity who underwent laparoscopic sleeve gastrectomy at five institutions in Japan. A percentage total weight loss < 20% at 1 year was defined as primary non-response. Parsimonious predictive models were developed based on the results of multiple regression analyses. A receiver operating characteristic (ROC) curve analysis was used to assess the discriminative performance for primary non-response. There were 28 (11.3%) primary non-responders. For discriminating primary non-responders, the areas under the ROC curve of the parsimonious model and actual percentage of total weight loss at 3 months after laparoscopic sleeve gastrectomy were 0.846 and 0.803, respectively. Cutoffs for the predicted percentage total weight loss using the model and actual value of percentage total weight loss at 3 months attaining 80% sensitivity were 30% and 22%, and those attaining 98% specificity were 22% and 15%, respectively.

Academic Significance and Societal Importance of the Research Achievements

世界中で増加している高度肥満症に減量・代謝改善手術は有効で、2 型糖尿病、高血圧等の併存疾患の改善も認める。医療経済面も利点が大きく、現在世界で年間40 万件以上の同手術がされている。しかし約20%の症例で術後減量効果不良となり、その機序は未解明である。術後1,3,6か月時の通院が推奨されているが、これらの時期における減量目標値はない。本研究では、減量・代謝改善手術後の減量効果不良因子を同定し、それらを用いた術後1年の減量効果を予測する式を作成した。この予測式および術後3か月の全体重減少率を用いれば、術後3か月における減量目標値が設定でき、より効果の高い減量外科治療を行うことが可能となる。
