Intraluminal impedance recording has made it possible to record fluid transport across the pylorus during the interdigestive state without filling the stomach. During antral phase II, fluid transport occurs with and without manometrically detectable antral contraction. Our aim was to investigate the relationships between ultrasonographic patterns of antral contraction, manometric pressure waves...

Based on evidence from two collected and treated clinical observations of hypertrophic pyloric stenosis in children of 5 and 12 months of age, the authors give their point of view on the unresolved issue of the etiology of hypertrophic pyloric stenosis. They emphasize that there are more and more factors to prove this is an acquired condition.

extract of echinops persicus is traditionally used for a long time in iran for treatment of cough and constipation. this extract is produced by activity of bug (situphilus spp.) on the plant. we documented its anti-tussive effect in rats in our previous study.the aim of this study was to assess the anti-ulcer effect of echinops persicus in an animal model. in this study we evaluated anti-ulcer ...

A 4.5-year-old Holstein-Friesian cow underwent surgery because of left abomasal displacement. Intra-operative palpation of the pyloric region revealed a phytobezoar. The abomasum containing the phytobezoar was exteriorized, and an incision was made directly over the mass in the region of the greater curvature of the pyloric part of the abomasum.

Administration of pentagastrin in depot form to 20 pregnant bitches produced pyloric hypertrophy in about 28% and gastroduodenal ulceration in about 16% of their pups. The two lesions were not necessarily found in the same individuals. Histological appearances of the pylorus in affected pups closely resembled those of human infantile pyloric stenosis.

Plasma concentrations of gastrin, somatostatin, neurotensin, and enteroglucagon were measured by radioimmunoassay in normal 30and 45-day-old neonates and age-matched infants with confirmed idiopathic hypertrophic pyloric stenosis. Plasma gastrin and somatostatin concentrations were similar in both groups, whereas neurotensin and enteroglucagon were significantly lower in the pyloric stenosis gr...
