Abstract
La exploración ecográfica del tubo digestivo es compleja y debe contemplarse dentro del protocolo diagnóstico de los pacientes con sintomatología digestiva como una técnica complementaria a otras técnicas de diagnóstico por imagen, fundamentalmente de la radiología. Estas técnicas de diagnóstico por la imagen, en un número elevado de casos, serán útiles para la aproximación al diagnóstico de las principales patologías que afectan al tubo digestivo en el perro. La ecografía abdominal requiere una mayor pericia por parte del explorador. La presencia de contenido alimenticio y gas dentro de su luz es una barrera que ha retrasado el uso de esta técnica como herramienta diagnóstica del sistema digestivo. El estudio ecográfico del estómago y duodeno proximal es, por sus características anatómicas y por su posición en abdomen craneal, más compleja que otras estructuras abdominales. Unas condiciones previas adecuadas que preparen el paciente, el desarrollo de protocolos de exploración apropiados y la descripción del patrón ecográfico y establecimiento de las medidas de normalidad para los diferentes pacientes serán imprescindibles para la realización correcta y completa de una ecografía de esta región. El conocimiento de la física del sonido, así como su interacción con las diferentes estructuras del organismo y el reconocimiento de los artefactos ecográficos son fundamentales para poder desarrollar un examen correcto de la cavidad abdominal y más concretamente de esta porción del tubo digestivo...
Ultrasound exploration of the digestive tract is complex and must be included within the diagnostic protocol of patients with digestive symptoms as a complement to other imaging techniques such as radiology. These diagnostic imaging techniques, in an important number of cases, will be useful in diagnosing the main pathologies that affect the digestive tract in dogs. The abdominal ultrasound exam requires great expertise from the sonographer. The presence of alimentary contents and gas inside the digestive tract is a barrier that has delayed the use of this technique as a diagnostic tool of the digestive system. The ultrasound exploration of the stomach and proximal duodenum is more complex than that of other abdominal structures because of their anatomical characteristics and their cranial position in the abdomen. The correct preparation of the patient, the use of appropriate exploration protocols and the description of the echographic patterns and the physiological dimensions for different patients will be essential for a correct abdominal examination. The knowledge of the physics of sound, its interaction with different body structures and the recognition of ultrasound artifacts are fundamental for a correct examination of the abdomen and, particularly, the digestive tract. An appropriate knowledge of the anatomy of stomach and duodenum is essential to establish their correspondence with physiologic findings and their normal echographig patterns. The anatomic relationships with different structures and their vasculature will complete the echographic examination of the digestive tract. Some authors describe a general examination protocol for the study of the digestive tract. There are few publications that describe a detailed protocol for the study of stomach and proximal and descendent duodenum in the dog. The distinctive features of this region are rarely taken into account in most cases...
