Figure 1 represents an intestinal tube in situ, the end having reached just beyond the duodenojejunal junction. The distal 8 inches of this tube have been perforated by numerous small openings. A suspension of barium is injected through the proximal end. When this suspension reaches the distal end, it escapes through all of the numerous perforations at practically the same time, and fills the entire duodenum in an unobstructed, isolated and homogeneous manner (Fig. 2). This simple method obviates the necessity of employing any special apparatus or of producing unphysiologic distal obstruction, in filling the duodenal curve. The method is of value for a roentgen-ray study of the normal duodenal curve and of pathologic variations (Figs. 3 and 4).1
