RESUMEN
CASE: We report the case of a 21-year old female with multiple surgeries. Her problem began after last surgery, which got complicated by a diaphragmatic perforation on the left side so it was necessary to repair the defect with a plastic prosthesis, since that time she complained of abdominal pain. In an abdominal computed axial tomography prosthesis was observed and by endoscopy its presence into stomach was confirmed, because its size and rigidity its endoscopic extraction was impossible, so it was surgically extracted. One and half month after surgery the patient's evolution was satisfactory. DISCUSSION: Migration is one of the most common complications of medical prosthesis placed into abdominal cavity. However precise incidence is unknown, neither intraluminal migration to the gastrointestinal tract. We didn't find previews reports about intragastric migration of a prosthesis that was used to repair a diaphragmatic defect.
