Haematemesis in infantile hypertrophic pyloric stenosis: the source of the bleeding.
Thirteen infants with haematemesis associated with hypertrophic pyloric stenosis were investigated in order to elucidate the source of bleeding. All 13 patients showed endoscopic evidence of oesophagitis, moderate in 4 and severe in 9. No significant gastric mucosal lesion was found. It was concluded that the site of the haemorrhage was the oesophageal mucosa in all 13 infants. Eleven of the patients experienced troublesome postoperative vomiting.
