My daughter, had that.
At 7 years old she had surgery for it. Laproscopic surgery.
It was fine.
She had the top Surgeon here.
It was a 1 hour surgery. General Anesthesia... with a Pediatric Specialty team. They all talked to us about it.
It was fine.
My daughter was a trooper.
After the surgery, she was in recovery for a few hours. Then we went home. She rested... and stayed home from school for a few days.
Went back to school with a note from me about what she can or cannot do. Her recovery was for 6 weeks.... ideally. With no heavy lifting or activities... SO that, the internal sutures... can heal FULLY... without splitting.
The Surgeon said that if not completely healed, and a child does heavy activity in the meanwhile, they can split the sutures.
And YES, Hernias can get strangulated. This is VERY dangerous. It happened to our Surgeon's own son. He said that if it strangulates and gangrene sets in, you only have 2 hours or so, to get into surgery and fix it. Or you lose that organ or their life.
You cannot predict, IF a Hernia will strangulate.
That is the danger of it.
With a Hernia... internal organs sticks out of that hole. In my daughter's case, it was probably her Ovary etc. or intestines.
I recommend, having the surgery.
My daughter, was having pain from it.
And after her surgery, she was HAPPY and told us. Because now, she has no pain and does not have to worry about it strangulating.
We explained everything to her, as did our Pediatric Surgeon
