In severe duodenal ulcers it may be necessary to remove the lower portion of the stomach called the pylorus and the upper portion of the small intestine called the duodenum.
32.
Bile may be forced into the stomach secondary to a weakened valve ( pylorus ), the presence of certain drugs including alcohol, or powerful muscular contractions and duodenal spasms.
33.
The "'G cells "'are mostly found in pyloric glands in the antrum of the pylorus; some are found in the duodenum and other tissues.
34.
The procedure involves a longitudinal resection of the stomach starting from the antrum at the point 5 6 cm from the pylorus and finishing at the fundus close to the cardia.
35.
This method of torture involved making an incision in the abdominal area, separating the duodenum from the pylorus, and attaching of the upper part of the intestine to a crank.
36.
In infants with hypertrophic pyloric stenosis, the pylorus is narrowed and the radio-opaque material will take on the appearance of a thin string as it passes through this narrowed channel.
37.
Secretin and cholecystokinin are released from cells in the duodenal epithelium in response to acidic and fatty stimuli present there when the pylorus opens and releases gastric chyme into the duodenum for further digestion.
38.
Occasionally, in medicine, abdominal organs may be described with reference to the "'trans-pyloric plane "', which is a transverse plane passing through the pylorus.
39.
After the B 12-haptocorrin complexes pass from the stomach via the pylorus to the duodenum, pancreatic proteases cleave haptocorrin from the B 12 molecules which rebind to intrinsic factor ( IF ).
40.
The end stage of type I and type II hernias occurs when the whole stomach migrates up into the chest by rotating 180?around its longitudinal axis, with the cardia and pylorus as fixed points.
