Aim: Multimodal perioperative rehabilitation in patients undergoing curative conventional colonic resection for cancer has not yet been studied in a multicenter setting. In 2005, a nationwide quality assurance program was initiated in Germany in an unselected patient population. Methods: The prospective multicenter data collection includes patients from 24 German hospitals. All hospitals had established ‘fast-track’ rehabilitation as the standard perioperative treatment in elective colonic resection, and all patients entered the registry. Results: 748 of 2,047 fast-track patients (36.5%) underwent open resection of colonic cancer. The median age of the 380 female and 368 male patients was 71 (26–96) years. Compliance was high for epidural analgesia (89%), systemic basic nonopioid analgesia (93%), ‘restrictive’ intraoperative intravenous fluids (81%), oral feeding (73%) and enforced mobilization (84%) on the day of surgery. Surgical complications were diagnosed in 20%, general morbidity occurred in only 13% of all patients, and 3 patients (0.4%) died in the early postoperative period. Readmission within 30 days of discharge was necessary in 27 patients (4%). Conclusions: Compliance with fast-track measures was high, and general morbidity was low in a population of patients undergoing multimodal perioperative rehabilitation for conventional colonic cancer resection.
