The ground state energy of the massive scalar field with nonconformal coupling \ensuremathξ on a short-throat flat-space wormhole background is calculated by using the zeta renormalization approach. We discuss the renormalization and relevant heat kernel coefficients in detail. We show that a stable configuration of wormholes can exist for \ensuremathξ>0.123. In the particular case of a massive conformal scalar field with \ensuremathξ=1/6, the radius of the throat of a stable wormhole a\ensuremath≈0.16/m. The self-consistent wormhole has the radius of throat a\ensuremath≈0.0141lp and the mass of the scalar boson m\ensuremath≈11.35mp(lp and mp are the Planck length and mass, respectively).
