Gastric gastrointestinal stromal tumors (GIST) have a distinct surgical therapy compared to gastric adenocarcinoma. Large oncologic margins and lymphadenectomy are not necessary rendering local resections suitable to treat the disease and spare the stomach. That may be accomplished through a minimally invasive approach. We present a case of a 67-year-old woman with an endophytic 3.5 cm gastric GIST located in the posterior wall of the gastric body that underwent an endogastric resection. Operation was uneventful. The patient was discharged in the following day. Pathologic examination showed free margins and a low grade GIST. Endogastric resection is a feasible option in endophytic GISTs located in the posterior wall of the stomach.
