Gastric the structure and the relationship between gastric ulcer

Gastric expansion is part of the digestive tract, esophagus, then, even under the duodenum. The shape and size of the stomach with its contents and the number of different filling, swelling, emptiness can be sources and tubular. There anterior and posterior stomach, the anterior and posterior wall connected with a bending, bending to the stomach and the small bend, the entrance to gastric cardia, export-pyloric. Stomach can be divided into four parts: cardia stomach at the bottom, stomach and the Department of the Ministry of pylorus. Gastric mucosal layer containing many glands, with its different parts into three kinds: cardiac gland, and the gastric glands pyloric glands. In gastric acid and pepsin, respectively by the gastric fundus (CARICOM) gland cells and the main wall secreted by the cells, the distribution of gastric glandular stomach about all the 4 / 5, but mainly to gastric body. From autopsy can confirm that on the occurrence of ulcers and gastric acid-related, which is good because the ulcer site of gastric acid production is not glandular region, and in recent contact with the curved side and the small area before the pylorus, which is pyloric glands, and gastric glands at the junction of place. The regional distribution of pyloric glands can sometimes along the lesser curvature on the lateral extension, so many small ulcer may occur in the top bend and cardiac region. Overall speaking on the stomach, than occurred in the anterior posterior common, if implemented gastric ulcer patients in the subtotal gastrectomy, after anastomotic ulcer in the same location is not in the residual stomach acid production, but in the neighboring anastomotic jejunum. Therefore, in general gastric ulcer and gastric antral gastric antrum bias at the junction of the side and a small curved lateral common. It has been reported that about 90% of patients pyloric glandular ulcer occurred in the District. Other parts of the ulcer is relatively rare.
