[Fiber endoscopy in the extraction of foreign bodies from the gastrointestinal tract].

23 patients that they swallowed foreign bodies, were treated. There were 16 male and 7 female, between 3 and 85 years old; 6 children and 17 adults. Of all, 7 were psychiatric patients. 15 foreign bodies were removed by upper digestive fiberendoscopy and 2, by procto/colonoscopy, without early nor late complications. 8 foreign bodies were eliminated spontaneously through the rectum/anus. Fiberendoscopy is an excellent method for treatment in these clinical problems.
