Do you know why he scheduled this? Maybe she is still having pain, or he feels he didn't get all the endo? Without the answers, the only advice I can offer is that laps, and other surgerys can cause scar tissue, which makes adhesions, which causes more pain. I have had 3 laps, and have adhesions now. My current doc was very hesitant to do more surgery, because as she said, "Someone has to stop doing surgery on you." And I have only had 3, others here have had many many more. My personal opinion is that it gets to be an ugly cycle. If the surgery is just to explore, maybe they can find other alternatives for the time being.
