The effect and risk factors for postoperative physical decreased exercise in patients with colorectal cancer

(Introduction) Patients after surgery receieve a physiologic stress and the risks due to delayed recovery. (Purpose) To evaluate the relationship between perioperative physical activity and postoperative outcome in colorectal surgery. (Patients and methods) This study enrolled 86 patients who underwent surgery for primary colorectal cancer at the our hospital between April 2021 and March 2022. The clinical characteristics, short terms outcomes, pre- and post-operative physical parameters were analyzed. Physical parameters were examined as follows; body weight, body mass index, percentage of body fat, grip strength, 6 Minutes Walking Test (6MWT) and 10-m gait speed. (Results) A total of 86 patients were included. Laparotomy and laparoscopic surgery were performed 10 and 76 cases. The rate of postoperative complications was 27.9%. All of physical parameter and performance (grip strength, 6 Minutes Walking Test were decreased after colorectal surgery. There was not correlation between short-term outcomes and 6MWT decreased by more than 10%. Surgical approach was the only dependent factor for 6MWT decreased by more than 10% (p＜0.05). (Conclusion) After colorectal surgery, all factors of physical parameter and performance are decreased, so that we should select laparoscopic surgery in addition to perioperative rehabilitation.
