Fig. 1From: Non-hypertrophic gastric outlet obstruction in the paediatric population: a case series with focus on managementEarly vs late endoscopic appearance of SAI. A Early endoscopic appearance of SAI: a case where endoscopy was performed within 24 h of SAI. The pyloric region was affected by the ingested acid, which seems to have had the longest mucosal contact due to stasis at the level of the pylorus. This case responded well to EBD. B Late endoscopic appearance of SAI: endoscopic appearance of SAI more than 3 weeks after ingestion. Extensive scarring and complete closure of the pylorus are noted. Case did not respond to EBD and needed surgeryBack to article page
