Submucosal elevation of the gastric fundus indicates that gastric mucosal elevation can be observed under gastroscopy. Submucosal elevation of the gastric fundus is a diagnostic term under endoscopy, which means that gastric mucosa in the fundus area can be observed under gastroscopy to show elevated lesions, which can be seen in gastric polyps, gastric smooth muscle tumor, gastric adenoma, gastric cancer, gastric lymphoma and other diseases, and may be benign or malignant. If necessary, further biopsy can be performed to confirm the diagnosis and to clarify the benign or malignant nature of the bulging lesion, which will help guide the subsequent treatment. Patients with submucosal elevations in the fundus of the stomach after gastroscopy are advised to go to the hospital, consult a medical professional and ask the doctor to make a judgment.
