The pressure in the oesophagus increases rapidly, and the oesophagus bursts at its weakest point in the lower third, sending a stream of material into the mediastinum and often the pleural cavity as well. In Mallory-eiss syndrome, forceful vomiting may produce a mucosal tear at the cardia rather than a full perforation. A veical split in the gastric mucosa, immediately below the squamocolumnar junction at the cardia is seen in 90% of cases. In only 10% is the tear in the oesophagusRef: Bailey and love 27e pg: 1072", 'role': 'assistant'}]
