Safety and Efficacy of Underwater Endoscopic Mucosal Resection for Type I Gastric Neuroendocrine Tumors Measuring 5-9 mm
Sponsor: Asian Institute of Gastroenterology, India
Summary
Study objectives: Primary objective: 1.To determine the histologic R0 resection rate of UEMR for type I gastric NETs measuring 5-9 mm. Secondary objectives: To evaluate: 1. En bloc resection rate 2. Immediate and delayed adverse events 3. Procedure time 4. Histologic quality of resection (deep and lateral margins) 5. Residual disease at resection scar on surveillance endoscopy oMetachronous gastric NETs during follow-up

Conditions
Interventions
Endoscopic mucosal resection under water
* Standard diagnostic gastroscope * Minimal insufflation followed by complete deflation of the gastric lumen * Lumen filled with normal saline to achieve complete submersion of the lesion * Optional marking for flat or ill-defined lesions * Snare capture with a 1-2 mm margin under water * Resection using standardized electrosurgical settings * Defect management (clips or coagulation) at endoscopist discretion * Retrieval of intact specimen * Specimen orientation and pinning on cork for histopathologic assessment
