Gastric volvulus is classified on the basis of the orientation of the rotational axis
The gastric organo axial volvulus is the most common
The volvulus can be further categorized as:
o primary or secondary depending on accompanying additional pathologies
o acute or chronic according its onset
o intra thoracic or intra abdominal according to its location
Determination of the type of volvulus usually is of limited clinical significance as the tightness and rapidity of the twist are more predictive of eventual gangrene
