Mesenteroaxial Gastric Volvulus

  • Etiology: diaphragmatic defect, stomach twists on its mesentery
  • Imaging: stomach is rotated around its short axis from lesser to greater curvature and stomach appears upside-down with antrum and pylorus superior to fundus and proximal body
  • Clinical: Borchardt triad – sudden epigastric pain, intractable retching, inability to pass nasogastric tube into stomach

Cases of Mesenteroaxial Gastric Volvulus

AXR and upper GI of mesenteroaxial gastric volvulus
AXR AP (above left) shows a distended air-filled stomach which on the AXR upright (above right) has a large air-fluid level within it. AP image from an upper GI (below) shows that by following the course of the feeding tube the stomach appears to be upside down with the pylorus of the stomach located superiorly to the gastroesophageal junction and the tip of the feeding tube to be in the second part of the duodenum.
