TUESDAY, Oct. 28, 2014 (HealthDay News) -- Exercising, eating a healthy diet, and learning relaxation techniques before colorectal cancer surgery appear to speed a patient's recovery, according to a small study published in the November issue of Anesthesiology.
The study included 38 patients (undergoing colorectal resection for cancer) who took part in a "prehabilitation" program and 39 who only did normal rehabilitation after their surgery. The prehabilitation program lasted an average of about 24 days and included: 50 minutes of aerobic and resistance exercises at least three days a week; a personalized nutrition program and whey protein supplementation; and lessons in relaxation methods to help reduce anxiety. After surgery, both groups of patients followed the same rehabilitation program.
According to the researchers, at the start of the study, patients in both groups walked about the same distance in six minutes -- approximately 425 meters. But immediately before and two months after surgery, patients in the prehabilitation group could walk significantly farther than those in the other group. Just before surgery, the patients in the prehabilitation group walked an average of 25 meters more in six minutes, compared with 16 meters less for patients in the other group. Two months after surgery, the average distances were about 23 meters more in six minutes than at the start of the study for the prehabilitation group and 22 meters less for the group that had no intervention.
"Prehabilitation prepares patients to withstand the stress of surgery so they are able to recover faster and function better after the procedure," lead author Francesco Carli, M.D., professor of anesthesia at the McGill University Health Center in Montreal, said in a journal news release. "Pre-surgery conditioning helps patients take an active role in their own recovery. We believe instituting prehabilitation before surgery when possible could improve health and recovery and reduce costs."
