The removal of a gastric mass may be minimally invasive if it is benign and small, or usually open if it is malignant and large. A mass in the stomach may be a benign tumor of the stomach, such as a gastric polyp, or early gastric cancer in situ. If the size of the tumor is relatively small, generally do not need to take open surgical treatment, can take minimally invasive surgery, under the condition of gastric endoscopy for surgical removal, postoperative pathological examination, to exclude the occurrence of malignant changes, generally faster recovery, the body damage is also relatively small. However, if the gastric mass belongs to malignant tumors, or the size of the tumor is relatively large, and also need to clear the surrounding lymph nodes, minimally invasive surgery can not be very good to achieve the therapeutic effect, need to take open surgery for radical surgical resection, to avoid postoperative recurrence. Surgical treatment of gastric mass, the choice of specific surgical style, the doctor should be based on the actual condition to determine.
