Diagnosis of Caustic Substances Poisoning
A doctor's evaluation Sometimes endoscopy The mouth is examined for chemical burns. Because the esophagus and stomach may be burned without the mouth being burned, the doctor may insert a flexible viewing tube (endoscope) down the esophagus to look for burns, particularly if the person drools or has difficulty swallowing. Directly inspecting the area allows the doctor to determine the severity of the injury and possibly to predict the risk of subsequent narrowing and the possible need for surgical repair of the esophagus. Endoscopy can be delayed if the person is too sick for the procedure. X-rays and computed tomographic (CT) scans may be necessary to evaluate the extent of the injury.
