Editing Gastric volvulus (section)

== '''Classification''' ==

* '''Anatomical''' (not clinically as important)
** Organoaxial (35%)
*** Stomach rotates around its       longitudinal axis (a transverse line between the pylorus and GOJ)
*** In most cases the antrum       rotates anteriorly and superiorly and the fundus posteriorly and       inferiorly, and the greater curvature comes to lie superior to the       lesser curvature
** Mesenteroaxial (65%)
*** Stomach rotates around its       short axis - a longitudinal line parallel to the gastrohepatic omentum,       connecting the middle of the greater and lesser curvatures
*** Pylorus rotates anteriorly       and superiorly (most common), but can sometimes move posteriorly from       right to left
*** The posterior of the       stomach lies anteriorly
** Combined (2%)
* '''Aetiological'''
** Primary (30%):
*** Rotation due to       laxity/disruption of the gastric ligaments. Due to agenesis, elongation,       or disruption (neoplasia, adhesions, skeletal deformity). More common       with chronic symptoms.
*** Usually mesenteroaxial
** Secondary (70%):
*** Volvulus due to other       anatomical abnormalities (paraoesophageal hernia (most common),       congenital diaphragmatic hernia, diaphragmatic eventration, phrenic       nerve paralysis)
*** Mostly organoaxial
* '''Onset'''
** Acute
** Chronic
