The patient was admitted in our institution and was treated for
gastric outlet obstruction conservatively.
We included patients with documented
gastric outlet obstruction caused by malignancy of stomach, pancreas or duodenum (confirmed by endoscopy or radiography).
Gastric outlet obstruction secondary to pancreatic cancer: Surgical vs endoscopic palliation.
Gastric outlet obstruction (GOO) is not a single disorder; it is a group of clinical and pathophysiological consequence of many disease processes that produce a mechanical barrier to gastric emptying.
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].
Bouveret syndrome is characterized by the migration of a gallstone through a cholecystenteric fistula into the proximal duodenum resulting in
gastric outlet obstruction. Bouveret syndrome is a rare phenomenon that most commonly occurs in females and the elderly.
We present an unusual case of a 68 year old man with
gastric outlet obstruction secondary to a non-ampullary primary duodenal signet ring cell carcinoma.
