Anatomical Relations Between the Esogastric Junction, the Diaphragm, the Pleura, and the Left Lung in Chronic Esogastro-bronchial and/or Esogastro-pleural Fistulas After Sleeve Gastrectomy.

Esogastro-bronchial and gastro-pleural fistulas after SG originated mostly at the top of the staple line. Eso-bronchial fistulas had a trans-hiatal passage with a proximal bronchial termination, while gastro-bronchial fistulas had a trans-diaphragmatic passage with a distal bronchial termination.
