Resumen
La cápsula endoscópica (CE) fue presentada a la comunidad médica hace 6 años como procedimiento videoasistido de diagnóstico por imágenes para el intestino delgado. Ha adquirido un papel importante para la evaluación de entidades patológicas de ese tramo del aparato digestivo, tales como hemorragia de diagnóstico desconocido, enfermedad celíaca, enfermedad de Crohn, lesiones de la mucosa intestinal debidas al uso prolongado de antiinflamatorios no esteroides, pólipos y tumores varios. La CE es útil para el monitoreo de los pacientes a quienes les fuera trasplantado el intestino delgado, a fin de detectar tempranamente posibles complicaciones, así como para evaluar la integridad del injerto. La CE esofágica resultó ser un método conveniente, efectivo y seguro para estudiar pacientes con esofagopatías. La CE tiene aún algunas limitaciones técnicas y visuales. No provee diagnóstico histológico ni permite ejercer maniobras terapéuticas. Existen todavía limitaciones debidas al costo elevado y a la falta de reconocimiento de reintegros. La cápsula podría quedar retenida en el tracto gastrointestinal, y en tal caso requeriría remoción quirúrgica o endoscópica. Las enfermedades que pueden producir esa retención incluyen estrecheces benignas o adherencias, estenosis por Crohn y lesiones tales como carcinoides o adenomas. Está contraindicada en el embarazo, en pacientes con estenosis del intestino delgado presumibles o conocidas, y antecedentes de cirugía mayor abdominal o disfagia. La futura cápsula ideal podría extender sus capacidades diagnósticas a todo el tracto gastrointestinal, si llevara varios detectores y sensores, y hasta podría adquirir potencialidades terapéuticas.

Abstract
Capsule endoscopy (CE) was presented to the medical world six years ago as a diagnostic video imaging modality for the small bowel. CE has gained an important role as an integral part of the evaluation of small bowel pathologies such as: obscure GI bleeding, Crohn's disease, celiac disease, small intestinal mucosal injuries due to chronic NSAID use, polyps and various tumors. CE serves as an efficient diagnostic tool also for the pediatric population. CE is useful in monitoring small bowel transplanted patients for the early detection of post transplant complications and for the assessment of graft integrity. The Esophageal Capsule Endoscopy was found to be convenient, sensitive, effective and safe method to evaluate patients for esophageal disease. CE still has some technical and visual limitations. It does not provide tissue diagnosis nor therapeutic options. Cost and reimbursement limitations still exist. The capsule may be retained in the GI tract, and may require endoscopic or surgical removal. Pathologies that may cause retention include benign strictures or adhesions, Crohn's strictures, and lesions as carcinoid tumor, or adenomas. CE is contraindicated in pregnancy, in patients with known or suspected small bowel stricture, previous major abdominal surgery or dysphagia. The future ideal capsule should expand its diagnostic capabilities to the entire gastrointestinal tract, carrying various detectors and sensors and may be even therapeutic potential.
