ABSTRACT
Resumen El vaciamiento gástrico normal refleja un esfuerzo coordinado entre diferentes regiones del estómago y el duodeno, y también una modulación extrínseca por parte del sistema nervioso central y factores del intestino distal. Los principales eventos relacionados con el vaciamiento gástrico normal incluyen el fondo de relajación para acomodar la comida, contracciones antrales para triturar partículas grandes de comida, contracción pilórica para permitir la liberación de comida del estómago y coordinación antropiloroduodenal de los fenómenos motores de relajación. La dismotilidad gástrica incluye el vaciamiento tardío del estómago (gastroparesia), vaciamiento gástrico acelerado (síndrome de dumping) y otras disfunciones motoras, como el deterioro del fondo de distensión, que se encuentra con mayor frecuencia en la dispepsia funcional. Los síntomas de la gastroparesia son inespecíficos y pueden simular otros trastornos estructurales.
Abstract Normal gastric emptying reflects a coordinated effort between different regions of the stomach and the duodenum, and also an extrinsic modulation by the central nervous system and distal bowel factors. The main events related to normal gastric emptying include relaxation of the fundus to accommodate food, antral contractions to triturate large food particles, the opening of the pyloric sphincter to allow the release of food from the stomach, and anthropyloroduodenal coordination for motor relaxation. Gastric dysmotility includes delayed emptying of the stomach (gastroparesis), accelerated gastric emptying (dumping syndrome), and other motor dysfunctions, e.g., deterioration of the distending fundus, most often found in functional dyspepsia. The symptoms of gastroparesis are nonspecific and may mimic other structural disorders.

Gastroparesis is a clinical term for gastric dysmotility or paralysis that presents without mechanical obstruction, but with functional obstruction. Nausea, vomiting, abdominal discomfort and abdominal distension may result from the functional obstruction of gastroparesis. Gastroparesis is frequently associated with such systemic diseases as diabetic mellitus and scleroderma or with certain operations such as vagotomy. Yet gastroparesis is rarely described in older children after viral infection. The authors observed a case of gastroparesis after pyretic symptoms. We report here on this case and its clinical consequences.
