In volvulus of the stomach the rotation of the stomach tore the spleen from its peritoneal attachments. The volvulus was of the "mesenteroaxial" type in a counterclockwise direction of 180°. The gastrocolic ligament was absent, probably on a congenital basis. Treatment consisted of reduction of the volvulus, reconstruction of the gastrocolic and gastrohepatic ligaments, and splenectomy. The mesentery of the ascending colon was redundant and was also plicated. The patient did well.
