The value of the duodenal intubation method (sellink modification) for the radiological visualization of the small bowel.

X-ray examination of the small bowel was performed in 52 patients by means of the conventional barium meal as well as the duodenal intubation method - Sellink modification - as a comparative study. The visualization of the jejunum and ileum except the terminal ileum was significantly better by the Sellink method compared to the routine examination. The intubation modification seems to be a valuable diagnostic supplement.
