title: Gasless laparoscopic surgery using a new intra-abdominal fan retractor system: an experience of 500 cases.
abstract: OBJECTIVE
  The aim of this study is to report the feasibility of a newly developed intra-abdominal fan retractor system for use in gynecologic laparoscopic surgery.
  
  
  METHODS
  Five hundred women undergoing gasless laparoscopic surgery using the abdominal wall lifting device were included in the study. The intraoperative and postoperative courses, and complications were examined.
  
  
  RESULTS
  The intra-abdominal retractor system provided adequate exposure in all cases, except for one patient with morbid obesity. Neither the presence of the intra-abdominal retractor blades nor the mechanical arm interfered with the placement of instruments during surgery. No complications related to the use of gasless laparoscopy were encountered in this study period.
  
  
  CONCLUSIONS
  The new intra-abdominal fan retractor system is feasible in gynecologic laparoscopic surgery.
