摘　　要：BACKGROUND Gastric gastrointestinal stromal tumor(GIST)is the most common etiology of gastroduodenal intussusception.Although gastroduodenal intussusception caused by gastric GIST is mostly treated by surgical resection,the first case of gastroduodenal intussusception caused by gastric GIST was treated by endoscopic submucosal dissection(ESD)in Japan in 2017.CASE SUMMARY An 84-year-old woman presented with symptoms of postprandial fullness with nausea and occasional vomiting for a month.Initially,she visited a local clinic for help,where abdominal sonography revealed a space-occupying lesion around the liver,so she was referred to our hospital for further confirmation.Abdominal sonography was repeated,which revealed a mass with an alternating concentric echogenic lesion.Esophagogastroduodenoscopy(EGD)was performed under the initial impression of gastric cancer with central necrosis and showed a tortuous distortion of gastric folds down from the lesser curvature side to the duodenal bulb with stenosis of the gastric outlet.EGD was barely passed through to the 2nd portion of the duodenum and a friable ulcerated mass was found.Several differential diagnoses were suspected,including gastroduodenal intussusception,gastric cancer invasion to the duodenum,or pancreatic cancer with adherence to the gastric antrum and duodenum.Abdominal computed tomography for further evaluation was arranged and showed gastroduodenal intussusception with a long stalk polypoid mass 5.9 cm in the duodenal bulb.Under the impression of gastroduodenal intussusception,ESD was performed at the base of the gastroduodenal intussusception;unfortunately,a gastric perforation was found after complete resection was accomplished,so gastrorrhaphy was performed for the perforation and retrieval of the huge polypoid lesion.The gastric tumor was pathologically proved to be a GIST.After the operation,there was no digestive disturbance and the patient was discharged uneventfully on the 10th day following the operation.CONCLUSION We present the second case of
