Polyps and submucosal bulges are not the same.
A polyp is a lesion in which the mucosa protrudes into the inner lumen and forms a confined bulge, usually a benign epithelial tumor. The color of the polyp is different from the color of the surrounding mucosa, and polyps are usually reddish. They can be categorized as hyperplastic polyps and fundic gland polyps. Polyps are usually treated by gastroscopic clamping.
Submucosal elevation refers to the elevation of the gastric and esophageal mucosa caused by lesions below the mucosal layer, and the elevated part of the mucosa is the same as the normal mucosa. It may be gastrointestinal mesenchymal tumors, benign gastric tumors such as smooth muscle tumors, etc. The lesion usually originates from the mucosal muscular layer or intrinsic muscular layer, etc. Mucosal bulges require ultrasound endoscopy to clarify the extent of the lesion and other issues before treatment can be formulated.
Therefore, polyp and submucosal bulge are not the same, in terms of lesion morphology, origin, treatment, etc. It is recommended to standardize the diagnosis and treatment under the guidance of a doctor.
