Fig. 1A 34-year-old woman with nausea and vomiting after gastric bypass
surgery. Patient has tight anastomotic stricture only seen on steep oblique
views because of its anterior location. Frontal spot view from single-contrast
upper gastrointestinal study shows barium in gastric pouch (small black
arrow), proximal jejunum (large black arrow), and blind-ending
jejunal stump (white arrow) secondary to Roux-en-Y reconstruction. No
stricture is seen at gastrojejunal anastomosis, but overlap between lower end
of gastric pouch and proximal jejunum obscures this region.
