Preoperative treatment with botulinum toxin A: a tool for giant groin hernia repair? Case report.

<b>Introduction:</b> Giant groin hernia is an unusual disease nowadays and its management can be a challenge for surgeons. The application of botulinum toxin A as a preoperative therapy could decrease the thickness of the lateral wall muscles, increase their length and increase the volume of the abdominal cavity facilitating the surgical repair. Morbidity and mortality due to high intra-abdominal pressure would decrease, allowing a minimal tension closure after reduction of the herniated viscera. <br><b>Case report:</b> We present the repair of two cases of massive inguinal hernia with loss of domain using preoperative abdominal wall injection of botulinum toxin.
