Background: Accidental corrosive ingestion is common in the paediatric age group. Severity may vary from no injury to a fatal outcome [1]. However, isolated gastric outlet obstruction (GOO), though rare, is a wellknown complication of corrosive ingestion. We present five such cases. Cases’ Summary: The mean age of presentation was 5.4 years. There were 4 males and 1 female. The average time duration between ingestion of the corrosive and presentation was 40 days. The common presenting symptoms were abdominal pain and non-bilious vomiting mixed with food particles seen in all five patients. Endoscopy was done in four patients - all four patients had antral and pyloric thickening. The scope could be negotiated across the pylorus only in one patient with difficulty. It could not be negotiated in the other three patients. Retrocolic, isoperistaltic gastrojejunostomy was done in four patients and pyloroplasty was done in one patient. Post-operative recovery was uneventful in all patients. Conclusion: Corrosive ingestion is an important cause of significant morbidity, especially in developing countries. Early diagnosis and appropriate endoscopic and/or surgical intervention usually lead to a good outcome.
