  We use an accessibility result of Delzant and Potyagailo to prove Swarup's
Strong Accessibility Conjecture for Gromov hyperbolic groups with no 2-torsion.
It follows that, if M is an irreducible, orientable, compact 3-manifold with
hyperbolic fundamental group, then any hierarchy in which M is decomposed
alternately along compressing disks and essential annuli is finite.
