Which is the investigation of choice in a case of stricture esophagus caused by corrosive poisoning ?
The corrosive injury is more common in females. Most of the patients were of younger ages. Acid ingestion was more common than alkali ingestion, and most had suicidal intentions. Early upper G.I. endoscopy has a definite role in diagnosing the severity of the injury and in planning the management. The best time to assess the injury is by 12-48 hours of ingestion of the corrosive substances. Most of the patients with corrosive injuries can be managed conservatively with follow up for the stricture, which is the most common complication that is often treated by dilatation.
