La endoscopia convencional valora de forma deficitaria las lesiones submucosas del tracto digestivo por la imposibilidad de su observación directa, ya que no permite determinar su tamaño adecuadamente, establecer un diagnóstico etiológico en la mayoría de los casos ni valorar la capa de origen del tumor. Sin embargo, la ultrasonografía endoscópica permite, en la mayoría de las ocasiones, solucionar estos problemas: logra diferenciar con cierta seguridad las lesiones malignas de las benignas, puede medir su tamaño y establecer su capa de origen. Es la técnica de elección para establecer la presencia y las características de un tumor submucoso y si éste es subsidiario de tratamiento; además, permite seleccionar los casos que pueden ser extirpados endoscópicamente sin excesivos riesgos. La ecografía hidrogástrica puede ser una buena alternativa a la ecoendoscopia para el estudio de las lesiones submucosas y la estadificación de tumores situados en el antro gástrico en los pacientes en que no se pueda disponer de esta técnica o no se pueda realizar. Es una técnica muy fiable, poco costosa, y muy bien tolerada por los pacientes. Presentamos a continuación el caso de una paciente que presentaba un tumor estromal gastrointestinal que pudo estudiarse mediante ecografía hidrogástrica, estableciéndose con precisión el tamaño, la capa de origen y la naturaleza maligna de la lesión
Evaluation of submucosal lesions of the digestive tract with conventional endoscopy is unsatisfactory since this technique does not allow direct observation or correct evaluation of the size and layer of origin of the tumor; therefore, in most patients an etiological diagnosis cannot be established with this procedure. However, in most patients, endoscopic ultrasonography can resolve these problems: to a fair degree of certainty, this technique can differentiate malignant from benign lesions, measure their size, and establish their layer of origin. Endoscopic ultrasonography is the technique of choice to establish the presence and characteristics of submucosal tumors and their suitability for treatment. Moreover, this procedure can identify tumors that can be removed endoscopically without excessive risk. Hydrogastric ultrasonography can be an effective substitute for echoendoscopy when evaluating submucosal lesions and for staging tumors of the gastric antrum when echoendoscopy is not available or in patients in whom it cannot be performed. Hydrogastric ultrasonography is safe, inexpensive and very well tolerated by patients. We present the case of a female patient with a gastric GIST that was evaluated using hydrogastric ultrasonography. The size, layer of origin, and malignancy of the tumor were accurately established
