A 51 year-old man with a history of type 2 diabetes for 12 years was referred to our hospital due to dizziness, fatigue, hematemesis, and tarry stool. He was diagnosed as having duodenum 3rd portion gastrointestinal stromal tumor (pT2N0M0, stage IIIB) and excised it. He tried to eat on the 7th day after the operation but had vomit. We arrange upper gastrointestinal series showing duodenal partial stenosis, was found to have gastroparesis. After the acupuncture and a small amount Chinese medicine treatment on the 19th day, his vomit and food intake were significantly improved. This case shows that acupuncture and traditional Chinese medicine can treat gastroparesis, and hopes to provide a medical reference for similar patients.
