Transdiaphragmatic pericardial washout post penetrating cardiac injury found incidentally at diagnostic laparoscopy.

A 22-year-old male presented following a precordial stab. He was haemodynamically and metabolically normal. Initial investigations did not reveal pericardial fluid or haemothorax. At diagnostic laparoscopy, we encountered haemoperitoneum and a diaphragmatic injury through which the heart was visible. After pericardial washout, laparoscopic repair was effected. This case highlights a potential problem with extended focused assessment with sonography in trauma (eFAST) in that it will only be positive if there is an accumulation of pericardial fluid. It also confirms the utility of diagnostic laparoscopy for penetrating left thoracoabdominal injuries and shows that principles of open surgery can be safely applied laparoscopically in select patients.
