We introduce and study a new concept of strongly $l_{p}$-summing $m$-linear operators in the category of operator spaces. We give some characterizations of this notion such as the Pietsch domination theorem and we show that an $m$-linear operator is strongly $l_{p}$-summing if and only if its adjoint is $l_{p}$-summing.
