Abstract
Gastric dilatation and volvulus (GDV) is an acute life-threatening abnormal accumulation of gastric gas (dilatation), which may be complicated by rotation of the stomach (volvulus) about its mesenteric axis. This chapter looks at pathophysiology, diagnosis and management, techniques and treatment. Operative techniques: Tube gastropexy; Belt loop gastropexy; Incisional gastropexy.
