Prospective, randomized , multicenter study comparing cholecystectomy performed with da Vinci Single Site Instruments™ to multi-port (four ports) laparoscopy.
* The primary objective of this study is to evaluate cosmesis, patient satisfaction and quality of life after robotic- assisted single incision cholecystectomy procedure using da Vinci Single- Site Instruments™ in comparison to a multiport laparoscopic approach.
* The secondary objective of this study is to assess the peri-operative clinical outcomes of robotic- assisted single incision cholecystectomy with da Vinci Single - Site Instruments™ in comparison to a multiport laparoscopic approach.
* The third objective of this study is to evaluate hernia incidence at 1 year and 18 months after surgery
