Perforation of a Substernal Interposed Ileocolon Caused by Right Thoracic Herniation

Abstract

Perforation of a retrosternal interposed ileocolon is rare. We present a case of perforation of the interposed colon on the ninth postoperative day, which subsequently herniated to the right pleural space. We suggest that the dilated haustral trapping and the associated "waterfall" effect may have resulted in incarceration of the colon. Careful dissection of the pleura in order to create a retrosternal tunnel, and the use of a suitable length of an esophageal substitute could prevent this complication.
