You cannot determine the severity of a gastric sinus bulge based solely on a 1 cm bulge. Depending on the specific nature of the antrum bulge, it can be inflammation, benign lesions such as polyps, severe atypical hyperplasia or cancer. If it is a benign lesion, the situation is not serious; if it is cancerous, the situation is relatively serious. If the gastric antrum bulge is an adenomatous, hyperplastic or inflammatory polyp, this this lesion is not serious and it is recommended that the polyp be removed under gastroscopy. If the gastric sinus bulge is caused by peptic ulcer, acid-suppressing drugs such as omeprazole and gastric mucosal protectants such as colloidal bismuth can be taken. In addition, the gastric sinus bulge tissue is submucosal lesions, such as fibroma, mesenchymal tumors, lipomas, etc. in the stomach, which can not be biopsied to clarify, and need to do ultrasound gastroscopy, abdominal CT, etc. to further clarify the nature. If the patient’s gastric sinus bulge is a malignant tumor by pathological examination, it needs timely surgical treatment, and if necessary, it also needs to cooperate with radiotherapy and other treatments. After the discovery of gastric sinus bulge, it is recommended to take a biopsy of the tissue at the lesion to clarify the nature, and develop the next treatment plan under the guidance of the doctor.
