The operation will be a success. While performing the operation she'll notice that there was something in his body inhibiting his control of chakra. Of course she'll fix that to and he'll become more than a one dimensional character. Kind of like the Simpson's episode where they take the crayon out of Homer's head (through his nostrils) and he becomes a genius.

I would like to see Rock Lee become a prosperous ninja. He has alot of pride and honor.
