Endofaster Robot for Gastroesophageal Submucosal Tumors: A Randomized Controlled Study

Starting soon · Not applicable

Conditions studied: Gastric Submucosal Tumors

In brief

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?

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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;
• American Society of Anesthesiologists (ASA) physical status class I-III;
• Voluntarily signed written informed consent.

You may not qualify if…

• 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;
• Pregnant or breastfeeding women;
• Failure to cooperate with follow-up.
