Gastric volvulus is a rare emergency in stomach
Organoaxial is more common than mesenteroaxial roatation and is associated with diaphragmatic defect
In adults the diaphragmatic defects are traumatic or paraesophageal hernias and in children they are congenital
Symptoms are often sudden and acute and treatment requires reduction of stomach and fixation with closure of diaphragmatic defect.
In 5-28% some form of gastric resection is required.
Dumping Syndrome is caused when the pyloric sphincter is bypassed or removed occurring in 20% of cases after distal gastrectomy.
