1 Applications of robot assisted surgery in gynecology Jan Persson Lund University hospital Sweden Jan Persson April 2009

2 Robotiv surgery = laparoscopic surgery with a sophisticated tool Most applications are scientifically well established concerning safety and oncological outcome ( trad. laparoscopy) Advanced traditional laparoscopy has not been generally implemented Robot VS traditional laparoscopy remains controversial Economic data comparing robot with traditional laparoscopy and laparotomy are missing

24 Radical trachelectomy 900 cases published (Shepherd 2008) 760 of the cases are vaginal trachelectomy with laparoscopic pelvic LND (Shepherd 2008) 43% attempt pregnancy; 70% pregnancy rate (Ramirez 2008) >45% of women <40yo with operable cancer theoretically suitable for fertility sparing surgery (Sonoda 2008) Jan Persson April 09

27 Trachelectomy Pros and cons, personal view Vaginal trachelectomy Robotic trachelectomy Documentation (+) Adoption of technique +/- ++ Tailoring of parametrial dissection Allowing nervesparing dissection Conversion to Radical hysterectomy Surgical time ++ -? Control of cervical transsection point Placement of cerclage / risk of rejection / erosion - ++? Jan Persson April 09

28 Recent aims Further reduction of set up and turnover times Further reduction of consol time 3 operations / day Minimize number and size of ports Minimize number of instruments Further improve perioperative care Increase research activity Side docking
