We study the topological 4-dimensional surgery problem for a closed connected orientable topological 4-manifold with vanishing second homotopy and whose fundamental group is isomorphic to a free product of an one-ended group with a non-trivial free group. Our result is related to a theorem of Krushkal and Lee.
