CTICasesTransverse Colon Herniation through Diaphragmatic Hiatus post-Esophagectomy

Imaging findings
Follow-up chest computed tomography six months after an esophagectomy shows herniation of the entire transverse colon into the left hemithorax. The colon has migrated through the widened diaphragmatic hiatus alongside the gastric conduit, with no evidence of strangulation or bowel obstruction.
Key takeaways
Herniation of abdominal viscera, such as the colon or small bowel, through the diaphragmatic hiatus is a known late complication of esophagectomy. It occurs due to the surgical widening of the hiatus and mobilization of intra-abdominal organs, and surgical repair is often considered to prevent the catastrophic complication of bowel incarceration or strangulation.
