Hi there,I'm sorry to hear of your failed muscle repair.Firstly, a muscle repair that fails is uncommon.Possible causes are:Your anatomy (weak or thin fascia over the muscle which tears at the stitch holes of the sutures and does not "hold" the stitch, or it is possible you have too much visceral fat ( if you lie on your back, is your tummy full and protruding above your rib cage, or hollow? If full, then a repair will not work well as it would need ot be closed too tightly and will not hold. In this case, you must lose some weight before re repair to deflate the visceral fat. Plastic surgery cannot access fat behind the muscle).Your post op activity. A muscle repair is really a hernia repair, and should not be stressed by any resisted activities for around 6 weeks post op.Your surgeon's chosen suture material - if it is dissolving, or was a weak suture, it might not hold.Your surgeons technique - the repair was not strongly enough constructed.Whatever the cause: ensure your visceral fat content is low before a re repair. Then, from your surgeons point of view, a RE REPAIR WITH REINFORCEMENT is necessary to cover all bases and give you the strongest possible repair so that this time it will hold.In my hands I use a permanent external mesh about 5cm wide overlaid on any repair I do if I judge that it may be weak - ie the fascia is thin. I've never used pigskin. I'm not saying there is anything wrong with it.Your surgeons is saying to you that reinforcement of the repair is necessary. This is logical and correct. If I were you I would have the repair reinforced this time. Maybe ask your surgeon why pigskin (allplastic ADM) as the reinforcement. Synthetic mesh made of similar materials to sutures is cheaper and when placed externally does not carry the risk of mesh placed intraabdominally. It is a safe use of mesh, and is cheap. Your surgeon might have great reasons to prefer pigskin, so worth asking why, and if there are cheaper reinforcement materials - there are!hope this helps,Please post how you go!Howard WebsterPlastic Surgeon.
