In endoscopic treatment for gastric submucosal tumors arising from the muscularis propria, does robot-assisted surgery yield a higher serosa preservation rate, shorter operative time and lower complication rates than conventional endoscopic procedures?
Aged 18 to 80 years old;
Submucosal tumors originating from the muscularis propria of gastric fundus, highly suspected as gastrointestinal stromal tumor (GIST) confirmed by endoscopic ultrasonography (EUS) and contrast-enhanced computed tomography (CT);
Tumor diameter ranging from 1.0 cm to 3.0 cm;
No active ulcer or bleeding on the lesion surface before operation;
Tumor adhesion to serosa with unclear interface shown on EUS;
High-risk GIST or distant metastasis indicated by imaging or endoscopy;
History of gastric surgery or radiotherapy;
High bleeding risk including coagulation disorders and patients unable to discontinue anticoagulant medications;

Robot system
DeviceAfter Marking and mucosal incision，Grasp the tumor or its pedicle with the robotic flexible arm, apply continuous and steady traction toward the luminal side to dynamically expose the anatomical space between the tumor capsule and normal muscular layer.

Postoperative fever rate
Postoperative fever is defined as a body temperature ≥ 37.5 ℃ within 7 days after surgery. All febrile cases during this period are included, including non-infectious absorption fever.
