(a) Barium meal follow through image demonstrating narrowing of the second part of the duodenum. (b) Barium meal follow through image demonstrates gastrojejunostomy with dilatation of part of the D2, D3 and D4 segments of the duodenum and proximal jejunal loops, with passage of contrast distally.

The contrast was seen to pass into the rest of the jejunal loops (Figure 1a,b).
(a) Axial contrast-enhanced CT scan of the abdomen (with oral and intravenous contrast) demonstrating incomplete annular pancreas narrowing the D2 segment of the duodenum. (b) Axial contrast-enhanced CT scan of the abdomen with curved reformatting (with oral and intravenous contrast) demonstrating incomplete annular pancreas narrowing the D2 segment of the duodenum.

Narrowing of a short segment of the jejunum (distal to the gastrojejunal stoma) with dilatation of the intervening D2, D3 and D4 segments of the duodenum and the proximal jejunal loop was noted, suggesting afferent loop dilatation (Figures 2a,b and 3a).
(a) Coronal contrast-enhanced CT image of the abdomen demonstrates narrowing of the loop of jejunum distal to the gastrojejunal stoma with dilatation of the afferent loop (D2, D3, D4 and jejunal loops proximal to the stoma.)
