Abstract. In a large metropolitan general hospital, a high incidence of congenital hypertrophic pyloric stenosis was noted in non-Caucasian groups. Bile-free.

US diagnostic criteria of HPS The main diagnostic criterion is measurement of the thickness of the muscular layer. In HPS the thickened muscle and elongated pylorus are fixed over time, which helps the operator to identify this condition.

Pyloric US examination is a dynamic investigation, which should be performed in a systematic way. Treatment is surgical with a pyloromyotomy in which the pyloric muscle is divided down to the submucosa.

An upper GI examination may also be performed if emesis continues post-operatively, in order to exclude a duodenal leak or to assess an incomplete pyloromyotomy or gastro-oesophageal reflux [ 16 ].

The pylorus is usually located slightly medial and posterior in relation to the gallbladder Fig. Support Center Support Center.
