Gastric outlet obstruction is a syndrome resulting from mechanical obstruction of stomach emptying.
Pathology
Etiology
Gastric outlet obstruction can be due to malignant or benign causes.
Malignant
- adenocarcinoma (second most common )
- GIST
- lymphoma (less common than other malignancies as it is a "soft" tumor )
- metastases
Benign
- duodenal or gastric peptic ulcers (most common )
- pancreatic pseudocysts
- gastric varices
- granulomatous disease, e.g. Crohn disease, sarcoidosis, tuberculosis
- gallstones (Bouveret syndrome): rare
- strictures, e.g. from caustic substance ingestion
- gastric antral web
- gastric volvulus
- Rapunzel syndrome
