If
gastric necrosis and perforation occurs, euthanasia should be seriously considered.
Plasma lactate concentration as a predictor of
gastric necrosis and survival among dogs with gastric dilatation - volvulus: 102 cases (1995 - 1998).
34 out of 166 dogs had
gastric necrosis (dead stomach tissue that had to be removed).
As the severity of
gastric necrosis increases, the prognosis decreases, reaching as high as 90 % mortality for severe necrosis, despite the level of surgical expertise.
Gastric necrosis and perforation can occur up to 5 days after surgery, especially if resection was performed to remove necrotic tissues.
