Cosmesis, Patient Satisfaction and Quality of Life After da Vinci Single Site and Multiport Laparoscopic Cholecystectomy

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
