Colonic perforation in a right atraumatic diaphragmatic hernia.

SUMMARY: A 38-year female with no prior medical or surgical history presented with pleuritic pain and respiratory distress. Imaging revealed a right diaphragmatic hernia with colonic content. At right anterolateral thoracotomy, a diaphragmatic hernia containing a perforated right hemi-colon was found. The colon was resected in the chest and continuity restored via a laparotomy. This case illustrates the risk of obstruction, ischaemia and perforation and highlights the importance of early identification and prompt surgical management to reduce morbidity and mortality.
