[Duodenogastric reflux in roentgenexaminations (author's transl)].

Duodenogastric reflux (DGR) favours gastritis, ulcer and carcinoma of the stomach, as well as bleeding from oesophagealvaricosis. DGR is seen regulary in roentgenexaminations of the operated stomach--with exception of selectiv proximal vagotomie--, and in approximately 30-50% in roentgenexaminations of the non operated stomach. Quantification of the DGR is possible by intraduodenal application of Barium or Jodcontaining substances via transpyloric tube, endoscope or intracholedochal T-tube, and cinematographical and electronic registration of the roentgenexamination.
