Postoperative death in sows as a result of gastric mucosal de-gloving at the pars oesophagea

It is well documented that pigs frequently die from postoperative acute gastric dilatation, and proximal gastric 'stress' ulceration. Three cases of gastric mucosal 'de-gloving' are reported. This was secondary to acute gastric dilatation and resulted in death from acute haemorrh...

Description
Summary:It is well documented that pigs frequently die from postoperative acute gastric dilatation, and proximal gastric 'stress' ulceration. Three cases of gastric mucosal 'de-gloving' are reported. This was secondary to acute gastric dilatation and resulted in death from acute haemorrhage. All animals had undergone major abdominal surgery. Histology confirmed that the proximal gastric mucosa had been 'de-gloved', or torn from the gastro-oesophageal junction, leaving exposed muscle fibres. This syndrome has not been reported previously. The postmortem appearances of this mechanical injury could easily be mistaken for extensive oesophago-gastric peptic ulceration. This has major implications for prevention.
