Missed Approach vs. Rejected Landing
As you know, Missed approach criteria is published for each approach (missed approach required climb gradients and paths). If you are talking about a go-around, that may be different than a missed approach.
If you decide not to land and you are beyond the missed approach point (a rejected landing), the missed approach procedures may no longer be adequate. At this point you would have had to already brief yourself on any published obstacle departure procedures and be ready to execute those.
