Long-term results of botulinum toxin type A in complex abdominal wall repair and review of the literature.

Administration of botulinum toxin (BTX) is being used in cases of complex ventral hernia for the reconstruction of the linea alba and closure of the abdominal wall. However, there are no published results regarding the long-term effects of BTX and its implication in hernia recurrence. Our purpose is to evaluate the outcomes in hernia recurrence of the administration of BTX in complex ventral hernia repair.
