Gastric cancer is the most common malignant tumor of stomach, for the treatment of gastric cancer, radical resection is the first choice in clinical practice, that is, radical 2 gastrectomy (radical 2 subtotal gastrectomy for distal gastric cancer) plus perigastric lymph node dissection, and at the same time, with postoperative chemotherapy or even molecular targeting drug treatment. After radical gastrectomy for gastric cancer, the increased frequency of bowel movement after surgery is mainly considered to be caused by low nutritional status after gastrectomy, abdominal fluid accumulation or even pelvic infection stimulating the rectum in the early stage, which can be cured after supplementing human albumin and anti-infection treatment. In the recovery period, the increase of bowel movement is mainly considered to be caused by too much water in fluid or semi-liquid, which stimulates the colon to move faster and leads to the increase of bowel movement, which can usually be cured after normal diet.
