Would a wound vac be a better option than packing every 2 hours? 6 weeks post op abdominoplasty. (Photo)

I have had multiple areas of wound dehiscence. Would a wound vac be better in this case? It feels like there’s tunneling under the opened wound and this will continue to open up. Looking back I would have not had this procedure. What else can I do to assist with the healing? My PS keeps saying to the wounds and they will heal but it seems like every week another area opens up.
