There are two types of gastric cancer surgery: open surgery will probably have a large incision of about 20 centimeters or so; minimally invasive laparoscopy may have an incision, or consist of several small holes. The pain is not the same. If it is open, the incision is usually painful for about 3-4 days, and if it is minimally invasive, the pain is about 1-2 days. With the method of analgesia, sometimes it is possible to achieve basically no significant pain. The general surgical options for gastric cancer are distal major gastrectomy, or proximal major gastrectomy and total gastrectomy. Either way, part or all of the stomach is removed and part of the stomach or all of the small intestine is needed to replace the stomach. In this case, the diet should begin with fresh, easily digestible foods. Avoid fried and very difficult to digest foods, this diet is not good for the small stomach or small intestine to replace the stomach.
