Alimentary Tract Surgery - GDV

1. Gastric Dilation Volvulus Syndrome / Gastric torsion

   • Deep chest dogs
   • Eat then exercise
   • Clinical signs
     • Depression
     • Salivation
     • Unproductive retching
     • Distended abdomen
     • Flank watching
     • Collapse
     • Tachycardia
     • Pale MM, increased CRT
   • Pathogenesis
     • Stomach dilates bc gas / fluid
       • Progress to torsion if stomach rotates
         • Rotation twists distal oesophagus & duodenum so nothing can leave stomach
           • Extends --> pressure on hepatic portal vein & caudal vena cava = reduced venous return
             • Hypovolaemic shock
               • Necrosis of stomach wall
   • Management
     • Used to stabilise prior to surgery
       • Orogastric intubation
         • Right lateral radiograph, use gravity, sitting / sternal
           • Measure tube nose to 11th rib
             • Pass through bandage in mouth
               • May require lavage
       • Percutaneous needle
         • Prepare, left lateral, aseptic prep over most distended part
           • Insert catheter directly into stomach
   • Surgery
     • Wide ventral-abdo clip
     • To decompress stomach
       • Return stomach to normal position
         • Evaluate organ viabilty
           • Gastropexy
