title: Evidence-based treatment of patients with rectal cancer.
abstract: Rectal cancer is a worldwide disease whose incidence has increased significantly. Evidence-based medicine is a category of medicine that optimizes decision making by using evidence from well-designed and conducted research. Evidence-based medicine can be used to formulate a reasonable treatment plan for newly diagnosed rectal cancer patients. The current review focuses on the application of evidence-based treatment on patients with rectal cancer. The relationship between perioperative blood transfusion and recurrence of rectal cancer after surgery, the selection between minimally invasive laparoscopic surgery and traditional laparotomy, choice of chemotherapy for patients with rectal cancer prior to surgery, selection between stapled and hand-sewn methods for colorectal anastomosis during rectal cancer resection, and selection between temporary ileostomy and colostomy during the surgery were addressed. Laparoscopy is considered to have more advantages but is time-consuming and has high medical costs. In addition, laparoscopic rectal cancer radical resection is preferred to open surgery. In radical resection surgery, use of a stapling device for anastomosis can reduce postoperative anastomotic fistula, although patients should be informed of possible anastomotic stenosis.
