Prehabilitation in patients undergoing colorectal surgery fails to confer reduction in overall morbidity: results of a single-center, blinded, randomized controlled trial.

Background: Currently, there are solely weak recommendations in the enhanced recovery after surgery (ERAS) protocol regarding the role of preoperative physical activity and prehabilitation in patients undergoing colorectal surgery. Studies in heterogenous groups showed contradictory results regarding the impact of prehabilitation on the reduction of postoperative complications. The aim of this study was to assess the impact of prehabilitation on postoperative complications in patients undergoing colorectal surgery within an ERAS protocol.
