Postoperative care for gastric cancer resection

When the stomach is completely or partially removed, a series of changes occur in the above situation: first, the digestive juice is partially or completely lost; second, the food enters the small intestine directly from the mouth and esophagus, and its temperature, osmotic pressure, and pH remain almost the same; third, the pylorus and pyloric glands lose their functions. Next, let's take a look at the conditioning after gastric cancer resection surgery.

Dietary conditioning after gastrectomy 1. Chew slowly and use the mouth to replace part of the stomach's digestive function. Oral saliva contains amylase, which can break down starch in food. Saliva also contains protein, phosphate, potassium, sodium, calcium and other substances that are beneficial to the human body.

Dietary adjustments after gastrectomy 2. Eat small, frequent meals.

3. Strictly control the quality of food. Choose fresh, clean, easy to digest, low volume, high protein, high energy and vitamin-rich food. The temperature of food should be between 40℃ and 50℃. Too cold, too hard, highly sweet, beverages, spicy condiments with strong irritation, alcohol, etc. are all restricted. Food suspected of being moldy, corrupt or contaminated should not be eaten.

In addition, patients with diarrhea should limit or reduce their intake of dairy products and fat; patients with anemia should regularly supplement vitamin B12 and iron preparations.
