Maligne
Magenausgangsstenose (Magenkarzinom) nach Anlage einer Gastroenterostomie: Das getrunkene Kontrastmittel tritt nicht über den anatomischen Weg in das Duodenum über, sondern gelangt in die unten am Magen anastomosierte Jejunalschlinge (am Schleimhautrelief gut erkennbar).

Peptic
duodenal stricture causing gastric outlet obstruction: CT diagnosis with endoscopic correlation. Sagittal images (f, detail g) images confirmed overdistended stomach with stagnant fluid (*). The contracted pylorus and proximal duodenum (arrowheads) showed hypoenhancing mural thickening (+) and depressed focal thinning of enhancing mucosal contour (thin arrows).

Peptic
duodenal stricture causing gastric outlet obstruction: CT diagnosis with endoscopic correlation. Axial (a, b) images confirmed overdistended stomach with mixed and fluid (*) content, normal, uniform mural thickness. Note air-fluid levels (thick arrows). No other abnormal findings, particularly concerning liver, peritoneum and lymph nodes.

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
