Gastric lipoma is considered a rare condition that may constitute a challenging diagnosis. A 51-year-old woman presented dysphagia and abdominal pain, and an upper digestive endoscopic study disclosed a gastric tumor located in the submucosa of the pyloric antrum. Conclusive diagnosis was established after repeated endoscopic biopsies, and the patient was subjected to an atypical gastrectomy, w...

Hypertrophic pyloric stenosis (HPS) is a common cause of non-bilious vomiting in infants. In USA, operation for HPS is one of the commonest surgical procedure performed on infants.1 Etiology remains poorly understood. A recent epidemiological survey from Sweden2 has noted a distinct difference in geographical distribution suggesting an environmental causation. A palpable pyloric 'tumor' is pres...

Using adult mongrel dogs, pyloric motor activity and gastric emptying observed by phototransducer (P.T.) under anesthesia and by strain gage transducer (S.G.T.) under consciousness. Pyloric motor activity and function were investigated in the dogs with distorted pylorus after instorations of Daclon tube, pyloric resection and pyloric stenosis. The pyloric sphincter responses to gastrin, pancreo...

The incidence of pyloric stenosis in the Mersey region rose from 1.54/1000 births in 1976-8 to 2.22/1000 births in 1986-8. Reliance on ultrasonography for diagnosis in the 1980s resulted in fewer 'tumours' being felt; diagnostic delay was not shortened overall but serial ultrasonography showed evolving lesions in six patients. Clinical examination and selective use of ultrasonography is advocated.

Little attention has been given in the past to the incidence and clinical features of hypertrophic pyloric stenosis in premature infants. We have observed three cases of this disease in very premature infants within a period of 18 months in one of the premature nurseries in the Simpson Maternity Hospital, Edinburgh. These cases are of special interest because continuous clinical records from bi...

In order to investigate the possible contribution of maternal emotional stress to the aetiology of infantile pyloric stenosis, 100 mothers of affected infants, 100 "normal" controls who had not sought medical advice at any time concerning feeding problems, and 50 mothers of children with spina bifida were interviewed. All completed the Life Events Inventory, which gives a quantitative measureme...

AIMS To find out whether the incidence of infantile hypertrophic pyloric stenosis (IHPS) has changed over the past decade, and if so, to investigate possible contributory factors. METHODS All infants undergoing pyloromyotomy for IHPS in Sweden between 1987 and 1996 were studied. Using the national patient registers the yearly incidence was determined and evaluated in relation to sex, latitude...
