Umbilical hernia due to surgery

My sister
aged 43 years. Has been done laproscopic surgery for gall bladder removal (gall bladder stone). After surgery he was diagnosed as umbilical hernia. Her navel was swelled. And surgeon said may be stitching was missed that place during surgery so the hernia was developed. Gap about 1.4 cm. Then again a surgery has done. But no result. Now the gap is increasing. And doctor said a major operation must be done, and truss(net) have to be placed to fill the gap.

She has also pancreatic cyst that was detected after the operation.

Recent Ultrasonographic Report:
Intestinal content are seen in subcutaneous layer of the supra para umbilical region which is coming throw a gap and is aggravated during cough reflex and intra abdominal pressure , the exact size of the gap is about 1.4 cm suggesting presents of para umbilical hernia.

Recently her mother has died, and she is always feeling so much mental pain for this.

Is there any medicine for this hernia, so that operation can be avoided? Can staphisagria be taken as gap is created by operation?
as the internal material(intestine) has come out or protruded through umbilicus(navel). And as there is a little high and hard swelling on exact the navel. Then how staphisagria join or fill up the gap without inserting the intestine material? As this is a mechanical process. I mean without correcting mechanical process how the medicine work?
