3 tasks (T1-3) in an open, LAP and robotic-assisted (RA) surgical technique. T1 intended to test 3D imaging and spatial relationships by using rings which had to be placed over cones. T2 tested dexterity and precision using a suture that had to be passed from instrument hand to hand through small eyelets. T3 tested dexterity in suturing of a simulated gaping skin incision. Each task was performed in a 3D mode using binocular vision for open performance, the ‘Viking 3Di Vision System’ for 3D-LAP performance and the da Vinci ® Surgical System in a 3D mode for RA-performance. Subsequently, the same tasks were repeated in a 2D mode (monocular by means of a blindfold, conventional LAP, da Vinci 2D mode). Results: Loss of 3D vision increased difficulty and time to perform a task independent of approach. Solving simple tasks in 2D vision took about 25% longer than in 3D vision. For more complex tasks 2D vision prolonged the procedure in 3D by about 75%. For easy tasks LAP and RA- performance were similar. For harder tasks performed under 3D vision, RA performance was faster than LAP performance. 3D-RA performance was superior to 2D-LAP performance, independent of the difficulty of the task. Conclusion: The more complex a task, the more 3D vision increased performance compared to 2D vision. Open approach was superior to LAP or RA procedures, independent of the task or vision. For harder than easy tasks, RA performance was faster than LAP performance under 3D vision but not significantly different under 2D vision, independent of the difficulty of the task. The importance of vision does not rectify to directly compare LAP surgery with RA surgery. The main difference between task performances seems to be the vision. 6.5 Impact of energy metabolism on weight reduction in bariatric patients A. Businger 1 , R. Galli 2 , T. Peters 1 , C. Christoffel-Courtin 1 , B. Kern 1 , M. von Flüe 1 , R. Peterli 1 ( 1 Basel, 2 Luzern) Objective: Morbidly obese patients should be carefully evaluated in an interdisciplinary manner prior to any bariatric treatment for risk analysis and for the choice of the best individual therapy concept. We tested the impact of preoperative indirect calorimetry and measurement of body composition by densitometry (DEXA) on weight loss of laparoscopic sleeve resection (LSG) and laparoscopic Roux- Y-gastric bypass (LRYGB) to determine which patient is a poor candidate for one of these two mainly restrictive procedures and may need a malabsorptive operation. Methods: Between 08/04 and 06/08 a total of 207 patients (female 76%, mean age 44 (21-67) years, mean initial BMI 44 (35-65) kg/m 2 ) were prospectively evaluated with preoperative calorimetry and DEXA. In 145 patients (70%), LRYGB was performed, in 60 patients (30%) LSG. The overall average follow-up time was 20 (6-45) months, follow-up rate one year after the operation was 98%, after two years 93%. The impact of the two methods on weight loss (expressed by excessive BMI loss at one and two years postoperatively) was tested by multivariate analysis. Results: Mean preoperative basal metabolic rate was 1983 (± 394) kcal for patients with LRYGB and 2057 (± 565) kcal for patients with LSG (p=0.343) and was reduced in 63% of all patients with no difference between the two operation types. Carbohydrate and fat oxidation did not differ between the two groups. Average excessive BMI loss after 1 year was 75 (14-147)% for LRYGB and 63 (9-121)% for LSG (p
