Abdominal wall hematoma after laparoscopic surgery: early treatment with selective arterial transcatheter embolization.

Bleeding from the site of a trocar insertion is a relatively frequent complication after laparoscopic surgery, despite precautionary techniques aimed at reducing such events. It may result in a hemoperitoneum, requiring emergency reintervention or large hematomas of the abdominal wall. In the latter case, although conservative treatment is possible, hospital stay is prolonged and large amounts of blood-bank resources are consumed. Early diagnosis and selective embolization of the bleeding vessel may reduce the severity and consequences of this complication.
