Congenital Prepyloric Gastric Atresia

Gastric Atresia

“…Bennett (1937), Touroff and Sussman (1940), and Fell (1951) found, as we did, the cause in a prepyloric diaphragm. Burnett and Halpert (1947) and Brown and Hertzler (1959) in other cases observed connective tissue up to 1 cm. in length in the pyloric area, completely occluding the pyloric channel.…”

“…It is possible now to resect the central part and slit the border radially. Brown and Hertzler (1959) reported on two children with connective tissue 0 6 cm. in length in the pyloric channel, found by a longitudinal incision of the pylorus.…”

A Rare Gastric Outlet Anomaly: Pyloric Ostium on Incissura Angularis

“…In pediatric studies, reported incidence is estimated to be 1 in 20,000-40,000 births, but incomplete obstructive lesions such as duodenal webs are even rarer, accounting for only 2% of these defects [6,7]. Although various rare types of gastric outlet anomalies including pyloric agenesis, pyloric stenosis, pyloric webs, duodenal webs, and Springer annular pancreas have been reported [1][2][3][4][5], in the English literature, we could not find any gastric outlet anomaly such as our patient's. In this case it was also interesting to see that with such an anomaly major gastric complaints were not present until the sixth decade.…”

“…Complete obstruction involving the gastric outlet is a rare condition that is usually due to gastric atresia, although it may be caused by extrinsic pressure from congenital peritoneal bands or by annular pancreatic tissue in the gastric wall [3]. Gastric atresia is usually produced by a membranous diaphragm that only affects the mucosa, although there may be more extensive obliteration of the lumen [4]. When gastric outlet obstruction is partial, symptoms may not appear until childhood or even adulthood.…”

Stomach

“…Brown and Hertzler (1959) reported three types of gastric obstruction on the basis of the anatomical findings of obstruction: (1) by the diaphragm; (2) due to an area of mucosal atresia; and (3) due to complete segmental aplasia of the gastrointestinal tract.
