Complete obstruction of the gastric antrum in children following acid ingestion.
We report on two children who experienced delayed complete obstruction of the gastric antrum following concentrated acid ingestion. Both patients required initial tube gastrostomy and subsequent antrectomy with intestinal reconstruction. Unlike the more common alkaline corrosives, ingested acids tend to spare the esophagus and gastric fundus. While gastric perforation and vascular collapse may occur immediately following overwhelming acid ingestion, the more common course is chronic gastric antral inflammation with subsequent fibrosis and, in some cases, complete stricture. Delayed surgical reconstruction is recommended to permit the acute inflammation and edema to subside.
