ABSTRACT
Resumen La enfermedad de Crohn (EC) es una enfermedad inflamatoria intestinal que puede afectar todo el tracto gastrointestinal; el intestino delgado es el segmento afectado en cerca del 50% de los pacientes, en los cuales el íleon terminal es el área más comúnmente comprometida por la enfermedad. Las estenosis intestinales son una complicación frecuente en la EC y aproximadamente 30% a 50% de los pacientes presentan estenosis o lesiones penetrantes al momento del diagnóstico. Las técnicas endoscópicas convencionales no permiten evaluar las lesiones del intestino delgado; es por esto que se desarrollaron técnicas como la enteroscopia y la videocápsula endoscópica, teniendo cada una de ellas sus ventajas e indicaciones. Se presenta un caso de un paciente con EC con fibroestenosis localizada en el íleon medio. No es una localización frecuente para este tipo de lesiones.
Abstract Crohn's disease (CD) is an inflammatory bowel disease that can affect the entire gastrointestinal tract. The small intestine is affected in about 50% of patients among whom the terminal ileum is the area most commonly affected. Intestinal stenosis is a common complication in CD and approximately 30% to 50% of patients present stenosis or penetrating lesions at the time of diagnosis. Because conventional endoscopic techniques do not allow evaluation of small bowel lesions, techniques such as enteroscopy and endoscopic video-capsule were developed. Each has advantages and indications. We present the case of a patient with CD with localized fibrostenosis in the middle ileum which is not a frequent site for this type of lesion.

BACKGROUND: Fibrostenosis of large airway due to tuberculosis is one of the most perplexing clinical problems not only because it can lead to respiratory failure but also because of difficulty in the management. No one technique, such as balloon dilatation or insertion of self expandable metallic steno, has proved totally satisfactory in the management of fibrostenosis. We evaluated the effect of laser therapy in patient with severe fibrostenosis due to tuberculosis. METHOD: We classified the fibrostenosis to three types by bronchoscopic finding - the diaphragm type: stenosed by fibrous diaphragm, sparing the tracheobronchial wall, the collapse type: stenosed by collapse of the wall due. to destruction of the cartilage, and the combined type: stenosed by nonspecific inflammatory scar tissue within internal lumen with collapse of the wall. We have treated 10 patients complaining dyspnea due to with severe fibrostenosis of the diaphargm or the combined type using a neodymiumyttrium aluminum garnet(Nd-YAG) laser through a flexible bronchoscopy. RESULTS: Eight of the 10 cases improved after laser therapy and maintained during a follow up period of average 31.9 months. All of the cases undergoing laser therapy showed no serious complication to need the therapy. CONCLUSION: The results of our present study indicate that the Nd-YAG laser therapy is an effective and safe method for the management of selective tuberculous fibrostenosis.
