Tack entrapment of the ilioinguinal nerve during laparoscopic hernia repair

Abstract

Nerve injury has a reported incidence of 2% during laparoscopic hernia repair. These injuries usually involve the femoral branch of the genitofemoral nerve and the lateral cutaneous nerve of the thigh. Recently, in an effort to decrease the size of the port sites, surgeons have been using 5-mm tacking devices. These devices penetrate tissue more deeply and in so doing may injure nerves not classically at risk, such as the ilioinguinal and the iliohypogastric. We report the first documented injury to the ilioinguinal nerve during laparoscopic hernia repair. In addition, we review the anatomy and technique in an effort to help avoid this complication in the future.
