This document discusses various filling defects that can occur in the gastric remnant after surgery. It describes 7 figures showing examples of different defects, including a suture granuloma appearing as a smooth tumor, a bezoar appearing as a mottled mass, gastric stump carcinoma appearing as an irregular narrowing, and recurrent gastric carcinoma appearing as tumor infiltration narrowing the lumen. It also mentions bile reflux gastritis, jejunogastric intussusception appearing as a large sharply defined filling defect, and gastrojejunal mucosal prolapse appearing as a large partially obstructing mass.

3. • Fig GI 15-1 Suture granuloma. Large mass at
the greater curvature side of the antrum
(arrow) projects as a smooth tumor into the
gastric lumen.21

4. • Fig GI 15-2 Bezoar. The mass of retained food
particles produces a mottled appearance.

5. • Fig GI 15-3 Gastric stump carcinoma. (A) Normal
gastric remnant and Billroth-II anastomosis after
surgery for peptic disease. (B) Irregular narrowing
of the perianastomotic region (arrows) several
years later represents a gastric stump carcinoma.

6. • Fig GI 15-4 Recurrent gastric carcinoma.
Tumor infiltration narrows the gastric lumen
(arrow).

7. • Fig GI 15-5 Bile reflux gastritis.

8. • Fig GI 15-6 Jejunogastric intussusception
(afferent loop) producing a large, sharply
defined filling defect (arrows).

9. • Fig GI 15-7 Gastrojejunal mucosal prolapse
producing a large, partially obstructing mass
in the efferent loop (arrows).
