Submucosal Tunneling Endoscopic Resection (STER) was initially described for esophageal lesions. However, performing STER in the stomach presents challenges due to the wide gastric cavity, complicating tunnel creation, thick mucosa, high vascularity, and difficulties in closure.
We present a 56-year-old patient with abdominal pain, diagnosed with a 50 mm gastric intramural GIST from the muscularis propria. STER was successfully performed, revealing a low-risk GIST. Key tips for gastric STER include creating a straight tunnel (?5 cm), checking alignment, noting increased vascularity as a proximity indicator, using a snare or basket, and exercising caution when passing the cardia.
