Gastric Volvulus - Classification

Classification

Organoaxial type In an organoaxial gastric volvulus, the stomach rotates around an axis that connects the gastroesophageal junction and the pylorus. The antrum rotates in opposite direction to the fundus of the stomach.

Mesentericoaxial type The mesentericoaxial axis bisects the lesser and greater curvatures. The antrum rotates anteriorly and superiorly so that the posterior surface of the stomach lies anteriorly. The rotation is usually incomplete and occurs intermittently. Vascular compromise is uncommon. This etiology comprises approximately 29% of cases of gastric volvulus.
