Abstract An abdominal lift for use in endoscopic surgery is described. The lift defines a substantial portion of a circle. It has a spoke portion and an upstanding member. Its surface may be mechanically compliant and may be coated with an adhesion prevention agent or a lubricous coating. The described method of use includes use of a starter lift followed by insertion of the abdominal lift. The abdominal lift is elevated to establish a pneumoperitoneum at or near ambient air pressure.
