Is open surgery or minimally invasive surgery usually used for gastrointestinal mesenchymal tumors? Whether open or minimally invasive surgery is performed, the principles of surgical standardization are followed. The benefits of minimally invasive surgery are cosmetic, less invasive and more acceptable to the patient. If minimally invasive surgery is performed, you need to visit a surgeon with experience. And minimally invasive surgery has its indications for people. For example, patients with tumors in the greater curvature of the stomach with a tip (smaller contact surface with the stomach) and no invasion of the tumor and surrounding organs are more suitable for minimally invasive surgery, because the area where the tumor meets the stomach is relatively small and can be easily removed with minimally invasive surgery. So it still depends on the condition of the tumor whether minimally invasive can be done or not. Most of the patients with gastrointestinal mesenchymal tumor have open surgery, right? The vast majority of patients have open surgery. Many patients with gastrointestinal mesenchymal tumors have mainly extraluminal growth (i.e. tumors growing outside of the gastrointestinal tract) and are prone to involve the surrounding organs, and gastrointestinal mesenchymal tumors are prone to rupture, thus inappropriate surgical approach can cause tumor dissemination. In addition, some huge endogenous tumors have their limitations in lumpectomy, and sometimes minimally invasive surgical techniques cannot meet the surgical specifications, so open surgery is needed.
