"Remove everything" is referring to removing anything foreign at the ends of the vas deferens before they make the repairs, ie- scarring, hemoclips (if used during your vasectomy), sperm granuloma/s, etc, etc.
I will about guarantee you that your repairs will be vas to vas. Not vas to epi, etc, etc.
If you are going to have your vasectomy reversed, go to someone that has the bar set as high as ICVR.
IMO, it will be hard to find someone that can compete with the level of service one gets at ICVR. I've already mentioned what makes them a superior choice, and unique in this thread.
And lastly, in your case, I think you should just get on with it instead of banging your head on this reversal stuff a whole lot longer.
Its got to be your call, and your choice. I can't imagine you banging your head, posting about this, and contemplating a reversal a whole lot longer. If something was bothering me that bad, I'd get on with it, and stop wasting my/your time, life, and thoughts on it.
I feel the majority of everything to be considered has already been mentioned in this thread (risks, facts, etc, etc).
