Design outcomes

Primary

Measure	Time frame
Preoperative primary endpoint: Does the preoperative body composition influence the postoperative change in body composition? Postoperative primary endpoint: Does the regular measurement of the body composition pre- and postoperatively with visualization and quantification of the changes have influence the change of the body?	—

Secondary

Measure	Time frame
Preoperative secondary endpoints: Does the preoperative body composition have influence on intra- and postoperative complications as well as the duration of the hospital stay? Postoperative secondary endpoints: The regular measurement of body composition pre- and postoperatively with visualization and quantification of the changes influences other parameters such as the initial extent of weight reduction, quality of life, psychological well-being, comorbidities, laboratory values, etc. (see secondary endpoints).	—
