A percutaneous technique of liver retraction in laparoscopic bariatric & upper abdominal surgery.

Background: Laparoscopic bariatric surgery requires retraction of the left lobe of the liver to provide adequate exposure of the hiatus and the stomach. Currently used approaches utilize retractors that require additional incisions and prolong operative time.

Objectives: A retrospective evaluation of the efficacy and safety of a percutaneous liver retractor in a large series of patients undergoing laparoscopic bariatric surgery.
