Pyloric stenosis is a narrowing of the opening from the stomach to the first part of the small intestine (the pylorus). [1] Symptoms include projectile vomiting without the presence of bile . [ 1 ] This most often occurs after the baby is fed. [ 1 ]
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
The pyloric sphincter, surrounding the pyloric orifice is a strong ring of smooth muscle at the end of the pyloric canal which lets food pass from the stomach to the duodenum. It acts as a valve , controlling the outflow of gastric contents into the duodenum [ 6 ] and release of chyme .
Gastrectomy, gastric bypass surgery, diabetes, esophageal surgery, absent or inefficient pyloric sphincter, pyloric stenosis Dumping syndrome occurs when food, especially sugar, moves too quickly from the stomach to the duodenum —the first part of the small intestine—in the upper gastrointestinal (GI) tract .
The duodenal bulb (also ampulla of duodenum, duodenal ampulla, or duodenal cap) is the initial, dilated portion of (the superior part of) the duodenum [1] just distal to the stomach; it begins at the pylorus and ends at the neck of the gallbladder.
Both stenosis and dyskinesia can obstruct flow through the sphincter of Oddi and can therefore cause retention of bile in the biliary tree and pancreatic juice in the pancreatic duct. Individuals with sphincter of Oddi dysfunction present with abdominal pain resembling that of structural or inflammatory disorders of the gallbladder, biliary ...
The pyloric tit sign is a radiological finding observed during barium studies in cases of hypertrophic pyloric stenosis. [1] It appears as an outpouching on the lesser curvature of the stomach, just proximal to the impression created by the hypertrophied pyloric muscle.
Pyloromyotomy is a surgical procedure in which a portion of the muscle fibers of the pyloric muscle are cut. This is typically done in cases where the contents from the stomach are inappropriately stopped by the pyloric muscle, causing the stomach contents to build up in the stomach and unable to be appropriately digested.
