RESUMEN
In 1988, Podestá et al pointed out that injury increases duodenogastric reflux, DGR. Therefore, the objective of this was to compare the amount of DGR in normal subjects, C group, and in patients with head injury, T group. DGR was assessed by intravenous injection of 99m Technetium+HIDA followed by aspiration of gastric juice. The amount of DGR was reported as the total percentagem of the injected rediotracer recovered in the gastric aspirate. Reflux values did not differ significantly between the two groups, C group-median of 1,60 for percentage, range of 0,13 for percentage - 3,01 for percentage and T group-median of 1,12 for percentage range of 0,04 for percentage - 4,4 for percentage, p>0,10. Our results show ta DGR is not increased in patients with severe head injury
