A surgical access apparatus adaptable to permit the sealed insertion of either the surgeons hand and/or surgical instruments during laparoscopic and endoscopic surgical procedures includes an access housing defining a longitudinal axis and having a first internal passageway configured and dimensioned to permit passage of at least one of a hand and an arm of a surgeon, and a base mountable to the access housing. The base may include a liner member positionable within an incision of a patient to at least partially line the incision. The liner member may have a first end for positioning within the body and a second end for positioning external of the body. A displacement member may be operatively connected to the access housing and to the second end of the liner member. The displacement member is adapted for movement to cause corresponding displacement of the second end of the liner member relative to the access housing whereby the liner member engages tissue forming the incision to at least partially retract the incision.
