In transposition of the viscera the stomach is also transposed. In such a case difficulties may arise in the diagnosis of pyloric cancer, as in a case described by Légroux.
The stomach may be found in hernial sacs. Mention has already been made of the presence of dilated stomachs in scrotal hernia. More frequently the stomach is found in umbilical hernias. In diaphragmatic hernia the stomach is found more frequently in the thorax than is any other abdominal viscus. In 266 diaphragmatic hernias collected by Lascher17 the stomach was found either wholly or partly in the thorax in 161 cases. The clinical consideration of diaphragmatic hernia, however, does not belong here.

Furthermore, the stomach may be displaced by tumors, enlargement of neighboring organs, tight-lacing, adhesions, and the weight of hernias. These displacements, however, are generally inconsiderable and of little importance.
In a case described by Mazotti18 the stomach, of which the pyloric portion was fixed by adhesions, was twisted around its long axis. Death was caused by uncontrollable vomiting.

RUPTURE OF THE STOMACH.
Sufficient attention has already been given to perforation of the stomach in consequence of diseases of its walls, such as ulcer, cancer, abscesses, and toxic gastritis.
