Abstract
A case of acute gastro-duodenal lesions which were caused by water-immersion stress was presented. The patient is a 33 year-old male was admitted to our hospital with a complaint of se-vere epigastric pain, while working on the sea. X-ray and endoscopic examinations showed acute lesions in the antrum of the stomach, the bulb and postbulbar region of the duodenum. These lesions were improved ten days later. The lesions were different from stress ulcers in rats induced by the restrained water-immersion method. Acute gastric lesions of the antrum were frequently accompanied by acute duodenal lesions. The pathogenesis of these lesions is still unknown. We have to analize each case of acute gastro-duodenal lesions in detail in order to make the pathogenesis clear.
