Barium swallow
Technique:
Barium swallow was performed with the patient in the erect position, initially with liquid barium, then with barium-soaked bread.
Preliminary screening fluoroscopy shows gastric lap band orientated closer to horizontal than to vertical with a gas bubble proximal to it. Delayed transit was observed through the oesophagus during both liquid and solid components of the study. Contrast outlines a small pouch proximal to the lap band. Contrast and food material passes through the lap band into the body of the stomach.
Conclusion
Slipped gastric lap band with proximal pouch formation. Delayed oesophageal transit to both solids and liquids.
