Stomach gas analyses in canine acute gastric dilatation with volvulus.

Background: The origin of the gas in the stomachs of dogs with acute gastric dilatation or gastric dilatation with volvulus (GDV) often is disputed.

Hypothesis: We tested the hypothesis that gaseous distention resulted from aerophagia.

Animals: Ten cases of GDV that were submitted to an emergency clinic were sampled intraoperatively.
