Rationale: Major upper gastrointestinal (MUGI) surgery for cancer is associated with postoperative weight loss. The aim of this study was to study changes in body weight, body composition and body energy content in patients on nutritional therapy during the first postoperative year after MUGI surgery. Methods: Body composition was assessed with dual-energy x-ray absorptiometry (DXA) preoperatively, 6 and 12 months postoperatively in 41 patients (men/women 27/14, age (mean (SD)) 60 (13)). Differences in body energy stores were calculated from changes in fat and fat free mass. Comparisons were done by analysis of variance for repeated measures with Bonferroni correction. Results: The greatest weight loss (mean (SD)) (3.9 (0.7) kg or 5.6%, p
