Chronic gastric volvulus.

Gastric volvulus is an abnormal rotation of the stomach around his axis. The chronic presenting, as the acute one, is considered as a surgical emergency. We report 4 cases of chronic gastic volvulus. In 2 cases, it was a mesenterico-axial volvulus while in the 2 other cases it was an organo-axial volvulus. The barium enema made the diagnosis in all cases. The volvulus was secondary to a hernia in 3 cases and an agenesis of left diaphragmatic dome with ligament laxity in 1 case. All the patients underwent surgery. The laparoscopic approach was used in two patients.
