Gastric volvulus in Nigerian patients: report of four cases.

Gastric volvulus is an uncommon foregut condition. Literature survey based on Medline search between 1993 and end of 1996 indicated there were thus far approximately 750 cases of gastric volvulus with 100 involving children. Gastric volvulus frequently presents in chronic or recurrent form and symptoms are usually non-specific causing delay in diagnosis. The acute type is however potentially lethal if not properly managed. Four cases, an acute volvulus in a child and three chronic lesions in adults are presented with a discussion of the pathology, aetiology, manifestations and treatment of the condition.
