Preoperative chemical component relaxation using Botulinum toxin A : enabling laparoscopic repair of complex ventral hernia

Background Repair of complex ventral hernia can be very challenging for surgeons. Closure of large defects can have serious pathophysiological consequences. Botulinum toxin A (BTA) has recently been described to provide flaccid paralysis to abdominal muscles prior to surgery, facilitating closure and repair.
