Abstract
An 81-year-old man with early gastric cancer chronic with renal failure was successfully treated by intragastric endoscopic surgery. He had early gastric cancer locating beyond the pyloric ring. After making a temporary gastrostomy under epidural anesthesia, a mucosal resection was performed using a Buess's endoscope. Operation time was 120 minutes. He was discharged from the hospital uneventfully. In conclusion, among minimally invasive surgeries for gastric cancer, this method seems to be advantagenus to lesions locating near the cardia and pylorus and can be recommeded for patients with risk factors such as elderly and same underlying diseases.
