“…Studies on cadavers, with retrograde injection of contrast media under pressure from the stomach, have confirmed this region to be the weakest part of the oesophageal wall (Bodi, Fanger & Forsythe, 1954). It is of interest to note that spontaneous oesophageal rupture which occurred in five neonates was always into the right pleural cavity (Hohf, Kimball & Bellenger, 1962), this presumably being related to the fact that in babies the distal oesophagus is situated more to the right than in the adult, with the aorta protecting its left side. Small & Ellis (1958) have drawn attention to the similarities between spontaneous rupture of the oesophagus and the syndrome of post-emetic bleeding from gastric mucosal tears (Mallory & Weiss, 1929).…”
