An Unusual Cause of Metabolic Alkalosis and Hypocalcemia in Childhood复制标题

儿童代谢性碱中毒和低钙血症的罕见原因

An abdominal ultrasound demonstrated a diffusely thickened and irregular pylorus with no evidence of external compression. Gastric outlet obstruction was confirmed with a fluoroscopic barium meal study, which showed forceful gastric peristaltic waves without opening of the pylorus and only a trickle of contrast agent entering the duodenum at 30 min. It was thought that the potential contribution of hypocalcemia-related pyloric spasm to the severity and chronicity of the vomiting was not significant owing to the absence of alkalosis, hypocalcemia, or abnormalities on the abdominal ultrasonography performed when he presented 2 months earlier.
