Chinese medicine has a good personalized adjuvant therapeutic role in the treatment of colorectal cancer, which can be used throughout all stages of colorectal cancer treatment, and can effectively reduce the occurrence of postoperative complications for patients undergoing surgery. Patients with colorectal cancer often suffer from qi and blood depletion, spleen and stomach qi deficiency and gastrointestinal qi stagnation, which are manifested as physical weakness, weakness of limbs, not thinking about eating and drinking, abdominal distension and fullness, and poor exhaustion and defecation. Some patients with improper diet, low postoperative activity, advanced age or weakness may also suffer from gastroparesis, complete or incomplete intestinal obstruction, which largely affects the recovery of patients and the smooth implementation of subsequent radiotherapy and chemotherapy.
