The duodenum is the shortest and deepest part of the small intestine, about 25 cm in length. It is a very important digestive organ because it receives gastric juice, pancreatic juice and bile. The duodenum is located between the stomach and jejunum, and its body surface is closer to the middle than the stomach. The duodenum is mainly divided into mucosa, submucosa, outer membrane, bulb, descending part, horizontal part and ascending part. Duodenum is also the most stable small intestine segment at this stage. If duodenal ulcer may show back pain, vomiting, and even shock in severe cases. The main causes are excessive pressure and irregular diet. The main way to prevent this disease is to pay attention to diet and prevent eating cold food or spicy food.
