Seifert fibred higher knot surgery

If the manifold obtained by surgery on a higher knot admits a Seifert fibration onto a 2-orbifold,
then only restricted 2-orbifolds can arise. I will report on joint work with Jonathan Hillman on
this, and relate it to older work about Dehn surgery on classical knots.
