I had inguinal hernia 3 years ago and I was offered either watchful waiting or surgery.
My doctor told me that in most cases, hernia repair is considered elective surgery, and that watchful waiting is a safe strategy for hernia treatment.
Under watchful waiting the patient is in the driver’s seat, and can decide to undertake surgery later should the hernia become too painful, unsightly, or bothersome, affect quality of life, or if they just get too worried about the risk.
The major risk for watchful waiting is that the hernia may become strangulated which would be an emergency situation. My hernia was reducible, meaning that it could be easily pushed back in place, and had low risk for incarceration. Despite this, I chose the operation with mesh and have had no problems. I was 65 at that time.
If you are elderly, another factor to consider is your age at diagnosis, and what your age may be if surgery is required. This is because if you choose watchful waiting, and then have the operation many years later, the operation will more complicated and risky because of your advanced age. Operations are more risky in your 70’s than in your 60’s, and in you 80’s than in your 70’s, and so on.
I found two research papers that focused on whether or not watchful waiting was an acceptable treatment option specifically for incisional hernias. They both came to the conclusion that watchful waiting is an acceptable treatment option.
One study involved 255 patients, the second 529 patients. The studies tracked the patients for about 5 years, the average of watchful waiters that eventually had surgery was 26%.
The number of Emergency Surgeries was small, but significant, with an average of 6% requiring emergency surgery. All of the emergency operation patients survived.
So if the odds above are accurate, if your mom chooses watchful waiting, she will have a 26% chance of having the surgery anyhow, and a 6% chance of requiring an emergency operation.
Overall, if it was me, and I had gone through what your mom has gone through, I would choose watchful waiting.
Good luck
