When is upper GI endoscopy recommended after caustic ingestion?

Upper gastrointestinal (GI) endoscopy after caustic ingestion is specifically recommended to assess the extent of injury to the esophagus and stomach, guide management, and predict potential complications. Performing the endoscopy within 24 hours of ingestion is crucial because it allows for early evaluation of mucosal injuries while still being within a reasonable timeframe to visualize any damage.

The first few hours after ingestion are critical; however, immediate endoscopy (within 6 hours) is generally not recommended due to the risk of exacerbating injury and the potential for findings to change as chemical reactions continue. Additionally, delaying the procedure beyond 24 hours may lead to complications such as fibrosis, which could complicate the evaluation and potential treatment.

Thus, endoscopy within 24 hours strikes a balance, providing timely assessment while minimizing risks associated with early intervention. This guideline optimizes patient outcomes following a caustic ingestion incident, allowing healthcare providers to make informed decisions based on the condition of the upper GI tract.
