Iatrogenic diaphragmatic hernia complicating nephrectomy: top-down or bottom-up?

Abstract

Hernias of the diaphragm are rarely reported as a complication of abdominal surgery. We review a case of a 47-year-old female who presented with dyspnoea and chest pain one day after left radical nephrectomy for renal cell carcinoma. Plain and cross-sectional imaging identified a large left-sided diaphragmatic hernia containing omentum, spleen, splenic flexure, and stomach. Our patient underwent a thoracotomy and, after hernia reduction, the diaphragmatic defect was repaired using non-absorbable sutures and a mesh. She made an uneventful recovery. The potential cause is discussed and the published literature on this rare complication is reviewed briefly.
