[Chronic volvulus of the stomach].

Gastric volvulus is an abnormal rotation of the stomach. The incidence seems to be equal for men and women, and all ages are represented. Gastric volvulus may present as an emergency or as a chronic condition. Acute volvulus is potentially lethal if unrecognized, while a chronic volvulus may cause symptoms for years if not treated. Gastric volvulus may be more common than previously estimated. Approximately 700 cases have thus far been documented. Two case reports of chronic gastric volvulus are presented, of which one was treated by laparoscopic surgery.
