Caustic Gastroduodenal Injury



Caustic Gastroduodenal Injury


Michael P. Federle, MD, FACR





Key Facts


Terminology



  • Gastroduodenal inflammation/injury due to acid or alkali


Imaging



  • Massive submucosal edema of esophagus and stomach on CT, with appropriate history of corrosive ingestion


  • Esophagus is organ most often injured



    • Classically damaged by strong alkaline agents


  • Gastroduodenal injury is next most common



    • Most likely to be damaged by strong acids


  • Acute: Mild to moderate severity



    • Gastric and esophageal, ± duodenal submucosal edema


    • Best evaluated by CECT


    • Caustic agents cause intense pylorospasm, so duodenal injury is less common


  • Acute: Severe



    • Pneumoperitoneum (perforation)


  • Chronic phase



    • Gastric outlet obstruction (antral scarring and fibrosis)


    • Linitis plastica: Small, aperistaltic stomach with effaced folds


    • Best evaluated by upper GI series
