Six dogs underwent high selective vagotomy and mucosal antrectomy (HSV+MA). The gross and histological change of dog’s stomach were observed at 4-6 months after operation. It was found that the reconstructed antrum healed well and there was no stasis and distension in the stomach .The appearance of the nerves in muscular layer of the antrum was normal. No serious gastritis and mucosal atrophy was observed. These results indicat that HSV+MA is a reasonable procedure for the treatment of duodenal ulcer.
