A 48-year-old man with early gastric cancer underwent distal gastrectomy and Billroth-I reconstruction using a circular stapler. On 18th POD, he complained of abdominal pain, nausea and vomit. Abdominal computed tomography and endoscopy demonstrated dilatation of the remnant stomach and edema of the anastomosis. Treatment with intravenous drip-infusion was made no improvement in clinical symptoms. When Bukuryo-in was administered on 54th POD, his complaints were dramatically reduced. He went on a fluid diet on 57th POD. On 72nd POD, he was discharged from our hospital on administration of Bukuryo-in. After 6 weeks, he was able to put an end to this therapy. At present, he is free from nausea and vomit.
