title: A multicentric prospective study evaluating the safety and efficacy of Kii®Fios®First Entry Trocar in laparoscopic bariatric surgery.
abstract: Laparoscopic surgery has evolved as an important field of surgery due to its clear benefits when compared to open laparotomy surgery. However, specific complications of laparoscopic surgery have been reported, of which the majority are complications associated with first entry to the abdominal cavity. The emergence of bariatric surgery, combined with the special considerations of the abdominal wall and cavity of obese patients, leads to seeking new modalities of access to the abdominal cavity in this specific population.Kii Fios First Entry Bladeless Trocar (Applied) is a new device that may allow surgeons to facilitate the creation of pneumoperitoneum. This prospective multicenter nonrandomized trial aims to evaluate the safety and efficacy of Kii Fios First Entry Bladeless Trocar in laparoscopic bariatric surgery.
  
  
  
  In the period between December 2013 and June 2014, 588 patients were included by 18 surgeons from several French hospitals to undergo laparoscopic surgery using Kii Fios First Entry Trocar as a first-entry trocar. The surgeons filled out a questionnaire assessing the safety and efficacy of the trocar for every patient.
  
  
  
  There were no mortality and no major complications. However, 11 cases (1.87%) of minor complications (liver and greater omentum injuries) were reported. The surgeons reported successful entry in less than 1 min for 70.58% of the cases.
  
  
  
  Kii Fios First Entry Trocar (Applied) is a safe and efficient method to establish first entry in laparoscopic bariatric surgery when all the recommendations are followed and respected.
