Robot arm takes on stomach tumors: safer surgery ahead?
NCT ID NCT07655674
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares a robot-assisted endoscope to standard endoscopy for removing small stomach tumors. About 110 adults with tumors between 1-3 cm will be randomly assigned to one of the two methods. The goal is to see if the robot helps preserve the stomach lining, shorten surgery time, and lower complications like bleeding or fever.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Endofaster surgical robot system
- What this could lead to
- If successful, this could make tumor removal safer and faster, reducing complications and recovery time for patients with stomach tumors.
- What could go wrong
- This is an early-stage, single-center study with only 110 participants, so results may not apply broadly. The robot system may not outperform standard methods or could have unexpected technical issues.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Aged 18 to 80 years old; 2. 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); 3. Tumor diameter ranging from 1.0 cm to 3.0 cm; 4. No active ulcer or bleeding on the lesion surface before operation; 5. American Society of Anesthesiologists (ASA) physical status class I-III; 6. Voluntarily signed written informed consent. Exclusion Criteria: 1. Tumor adhesion to serosa with unclear interface shown on EUS; 2. High-risk GIST or distant metastasis indicated by imaging or endoscopy; 3. History of gastric surgery or radiotherapy; 4. High bleeding risk including coagulation disorders and patients unable to discontinue anticoagulant medications; 5. Pregnant or breastfeeding women; 6. Failure to cooperate with follow-up.
