In majority of cases you will not be able to block it completly, unless you go for full restriction of outgoing ports/protocols except the ones needed by your users and then you also need to check for integrity of those (HTTP inspection, proxy server for HTTP/HTTS request)
P2P are known to tunnel inside other protocols (HTTP and HTTPS are usually preferred) and mechanisms (toredo, 6to4, etc). Most use some level of encryption and even some IPSes are not able to cope with that - are are able to dectec only parts of traffic. Dynamic ports, upnp, megnet links, and a lot more.
