We report the study of $B^{+} rightarrow pbar{Lambda} K^+ K^-$ and $B^{+} rightarrow bar{p}Lambda K^+ K^+$ using a pair data sample recorded on the resonance with the Belle detector at KEKB. These include the observations of decay modes with the corresponding branching fractions ( $B^{+} rightarrow pbar{Lambda} K^+ K^-$ ) $(4.22^{+0.45}_{-0.44}pm 0.51) times10^{-6}$ , ( $B^{+} rightarrow bar{p}Lambda K^+ K^+$ ) $(3.81^{+0.39}_{-0.37} pm 0.45)times 10^{-6}$ , ( $eta_c rightarrow p bar{Lambda} K^-$ ) $(2.9^{+0.4}_{-0.3}pm 0.4)times10^{-3}$ and ( $B^{+} rightarrow pbar{Lambda} phi$ ) $(0.818 pm 0.215 pm 0.078)times10^{-6}$ , where denotes the decay branching fraction and the intermediate resonance decays are excluded in the four-body decay measurements.
