摘要：

We prove the impossibility of cylindrical thin-shell wormholes supported by matter satisfying the energy conditions everywhere, under reasonable assumptions about the asymptotic behavior of the -in general different-metrics at each side of the throat. Besides, we establish necessary conditions for the possibility of non-exotic thin-shell wormholes.
