Hello moonstar,
Hopefully someone will see your message who has had similar surgery.

I do know that sometimes this happens with laparoscopic surgery. My daughter had a kidney removed years ago and the surgeon told us how many scars she would need but in the end she had more and one of them was much larger and higher than he said it would be.

It does seem strange that you have 3 incisions and yet the actual report only mentioned the 2.
