CTICasesLap-Band Induced Pseudo-Achalasia
Imaging findings
Chest radiograph and chest CT show severe, diffuse dilation of the thoracic esophagus containing an air-fluid level, with a gastric band (Lap-Band) visible at the gastroesophageal junction.
Key takeaways
Laparoscopic adjustable gastric banding (Lap-Band) can cause severe esophageal dysmotility and outflow obstruction if the band is placed too tightly or slips. This results in pseudo-achalasia, characterized by massive esophageal dilation and fluid retention, placing the patient at high risk for aspiration pneumonia.
