Hypertrophic stenosis of the pylorus is a frequent congenital abnormality, characterized by hypertrophy of the circular muscle layer of the stomach in the region of the pylorus which needs obligatory surgery for correction. The common age at which this alteration appears is from three to six weeks with non bilious vomiting that progresses continuously to a state of permanent and incontrollable vomiting We present the case of a less than six weeks old baby which had shown no symptoms until two days previous to consultation, starting clinical signs with uncontrollable vomiting that required an echography which did not clearly show the underlying pathology. For this reason , a series of oesophagogastroduodenal radiographies was performed which showed an obstructed pass of the contrast to the duodenum. Therefore the diagnosis of stenosis and complete pyloric obstruction was made, and a few hours later the baby underwent successful surgery. Due to the absence of symptoms previous to the uncontrollable vomiting, its sudden appearance, and the little diagnostic help of the echography, we report the present case, and make a short actualisation, emphasizing diagnostic aspects and differential diagnosis in cases of vomiting for the age of the patient.
