Biochemical Syndrome in Adult Pyloric Stenosis, a Clue to Diagnosis in Emergency Department

Characteristic biochemical changes have been documented in patients presenting with the symptoms and signs of gastric outlet obstruction. These changes usually consist of hypochloremic, hypokalemic metabolic alkalosis and hypocalcaemia with or without renal failure. The aim of this report is to highlight these biochemical abnormalities again. Moreover, we suggest conversely that the presence of these changes should prompt the clinician for further evaluation to rule out gastric outlet obstruction especially in the emergency department. Early intervention resulted in dramatic improvement in patient’s clinical and biochemical status.
