Thoracic Epidural Versus Intravenous Patient-Controlled Analgesia after Open Colorectal Cancer Surgery

The aim of the study was to compare thoracic epidural analgesia (TEA) and intravenous patient-controlled analgesia (IV-PCA) after open colorectal cancer surgery. This prospective study included sixty patients scheduled for elective open colorectal surgery and randomized to either postoperative IV-PCA with morphine (n=30) or TEA with a mixture of levobupivacaine, fentanyl and adrenaline (n=30). Th e primary outcome was return of bowel function. The secondary outcome was quality of postoperative analgesia at rest, on coughing and during mobilization. Intermediate outcomes included patient satisfaction, time out of bed, rate of side effects and postoperative complications, and time of discharge. Recovery of postoperative ileus occurred sooner (p
