K28.5: Gastrojejunal ulcer : chronic or unspecified with perforation

The small intestine is the longest section of the digestive tract. It consists of 3 sections. The 1st section begins immediately after the stomach and is called the duodenum. The gallbladder and the pancreas secrete the digestive juices in this section. The jejunum and ileum sections come next. The nutrients are absorbed into the blood from the food in the small intestine. The small intestine is followed by the large intestine.

The small intestine is lined with mucous membrane. The mucous membrane of your small intestine is severely damaged in one place. As a result, a deep wound has formed in the mucous membrane of your small intestine. A hole has developed from the wound. The wound has existed for a considerable time.

It is possible that surgery was performed on your stomach and intestines in the past. In the process, certain parts of the intestines or stomach may have been removed and reattached. As a result, gastric acid may get into the small intestine and damage the mucous membrane of the small intestine.

Because of the wound, you may have pain in your stomach. It is also possible to feel nauseated and your stomach may feel unpleasantly full. You may feel exhausted. If a hole develops via the wound, you may then have various other symptoms. It may be that the hole will connect the small intestine to another organ. As a result, this organ may then be damaged. It is also possible that the hole will connect the small intestine to the abdominal cavity. In that case, you may get very severe abdominal pain. The abdomen may also feel very hard.
