Primary gastric volvulus: a report of two cases

Gastric volvulus is an uncommon cause of gastric obstruction. It can be classified as primary when no underlying condition is identified as the cause for the rotation. An acute presentation includes typical symptoms and is frequently detected by imaging studies. Chronic cases present with intermittent vague symptoms and imaging studies may be normal during the symptomatic interval. The lack of specific symptoms and signs delays the diagnosis of chronic volvulus. However, appropriate treatment demands prompt diagnosis. We report two cases of primary gastric volvulus, with chronic or subacute symptoms and normal imaging studies during the asymptomatic periods. Both were treated surgically and had an uneventful follow-up.
