It would seem, from the studies of Carter and Powell (1954) and of McKeown, MacMahon and Record (1952), that both genetic and environmental factors play a part in the aetiology and development of infantile pyloric stenosis. The latter group of workers have stressed the importance of postnatal environmental influences. Their studies, based on data derived from more than 1,000 cases treated in th...

The diagnosis of hypertrophic pyloric stenosis (HPS) with ultrasonography (US) is dependent on measurements of pyloric diameter (PD), pyloric length (PL), and muscle thickness. The authors were unable to confidently diagnose the condition with US in 45% of patients who underwent surgery for HPS because all three criteria were not fulfilled. An overall measurement of the "amount" of pyloric hype...

Infantile hypertrophic pyloric stenosis (IHPS) results in electrolyte disturbances due to persistent vomiting. Though the significance of hyperventilation in metabolic acidosis is established, debate continues regarding hypoventilation in metabolic alkalosis. We present six cases of respiratory depression requiring ICU admission in infants with hypochloremic, hypokalemic metabolic alkalosis due...

A neonate with patent urachus (PU) who later developed hypertrophic pyloric stenosis (HPS) is being reported. The newborn was first operated for PU; post-operatively he developed persistent vomiting and radiological workup confirmed HPS. Pyloromyotomy was performed with an uneventful recovery.

An association between blood group A and cancer of the stomach was first reported by Aird, Bentall, and Fraser Roberts (1953). Further associations between blood groups and gastrointestinal disorders have since been described (Clarke, 1964a). This paper reports an investigation into the ABO blood group distribution and salivary secretor status of patients with infantile hypertrophic pyloric ste...

BACKGROUND The diagnosis of infantile hypertrophic pyloric stenosis (IHPS), although traditionally clinical, is now increasingly dependent on radiological corroboration. The rate of negative exploration in IHPS has been reported as 4%. The purpose of our study was to look at elements of supportive clinical evidence leading to positive diagnosis, and to review these with respect to misdiagnosed ...

A full-term newborn female presented with non-bilious emesis immediately after feeding and abdominal distension on day one of life neither palpable mass nor electrolyte derangements. The baby was initially admitted to rule out gastrointestinal obstruction versus sepsis as a cause vomiting distension. Initial imaging studies involving an upper (GI) series showed at the level duodenum, but it onl...
