I loathe all surgery and avoid it whenever possible. My knees, rotator cuff, shoulder etc were all candidates for surgery thru the years but since it was elective, I refused (just like the PEG). So for me to recommend that you go back in and get the flap redo is saying something. If, God forbid, my flap fails, then I definitely get it redone. BTW, I was also told I had the maximum radiation by more than one doctor only to have them change their mind and hit me with another week of radiation at 5GY a day bringing my total in the exact same area up to 97GY. The radiologists claim it's because the second round was CyberKnife which is more accurate than IMRT so they could calibrate it to enter at different angles. Good luck.
