Abstract
We will describe two cases of gastric perforation due to ingestion of foreign body successfully treated by endoscope. Ingestion of tooth pick for octopus cake during drinking caused localized peritonitis with small amount of free-air in the abdominal cavity for 60 years old woman. Ingestion of wire by mentally retarded homeless man with 53 years old caused marked free-air in the abdominal cavity without severe symptom. By endoscopic evaluation to specify the site of perforation, foreign body identified as a toothpick or wire were observed and removal of foreign body were carried out successfully. Though clinical symptom of gastric perforation due to penetrating foreign body is less severe than those due to peptic ulcer, differential diagnosis were difficult. We can conclude that immediate endoscopy were essential for diagnosis and treatment for those condition.
