Enhanced recovery programme (ERP) includes early postoperative mobilization and ambulation the day of surgery. Data suggest that orthostatic symptoms prevent a large number of patients (up to 50%) from ambulating the day of surgery.~The investigators plan to include 50 patients scheduled for colorectal surgery and bariatric surgery in an ERP.~The primary endpoint will be the ability to get out of the bed and sit in an armchair. Orthostatic symptom will be recorded. The secondary endpoint will be a 6-min walk test (6-MWT). This test will be performed before surgery, 3 hour after the end of surgery, and 24 hour after surgery. The day of surgery a 2-min walk test (2-MWT) will be realized.~Correlation of the ability to early ambulate and postoperative course (adherence to ERP, complications) will be analyzed.
