A portal assembly for positioning within an incision to access an underlying body cavity including a collar and a compressible portal member. The collar includes an elongate member that defines a longitudinal axis and has a longitudinal passageway. The portal member includes one or more longitudinal ports for passage of a surgical object. The portal member is positionable within the longitudinal passageway of the collar to thereby adjust the length of the portal assembly within the incision.
