gastric outlet obstruction

Gastroenterology A manifestation of gastric dysmotility; the rate of gastric emptying is controlled by duodenal receptors for fat or acid Etiology Ulcers, benign or malignant tumors, inflammation–cholecystitis, acute pancreatitis or Crohn's disease, caustic strictures, pyloric stenosis Clinical Vomiting–often daily, intermittent epigastric pain; GOO may occur in neonates associated with antral hyperplasia, which has been attributed to therapy with PGE1, used to maintain patency of the ductus arteriosus in the face of congenital heart disease

Acute gastric volvulus is an uncommon, and often unrecognised, surgical emergency that should be considered in patients who present to the emergency department with severe epigastric pain and evidence of gastric outlet obstruction. If the diagnosis is in doubt (and this is often the case), imaging studies are important.

Less common symptoms include epigastric pain or acute gastrointestinal bleeding, and vomiting caused by gastric outlet obstruction. Gastrointestinal stromal tumours (GIST) account for 1-3% of all resected gastric tumours and are the most common solitary, asymptomatic submucosal masses found in the stomach.

Although surgery for established gastric outlet obstruction is technically successful in up to 90% of patients [6], it is often associated with a prolonged hospital stay and sometimes with poor function of gastroenterostomy [7].
