+//Analysis of technical aspects.//
+\\
+We analyze the instrument trajectories and study any correlation with the clinical data. The analysis is performed by using motion data related metrics applied on the signals available from the Da Vinci export interface. About more than 20 different metrics are computed including duration, path length, average linear velocity, average acceleration, average jerk, bi-manual dexterity, motion smoothness, depth, idle time, relative phase, response orientation, economy of volume and working volume of the instrument’s positions. Each metric is computed, if applicable, for the right and left side and their combination. The metrics are computed on the whole procedure, as well as on the main surgical phases and steps, manually defined from the synchronized videos. From these metrics, classification approaches are then used to identify similar patterns 1) within populations of patients with similar clinical characteristics, 2) within populations of patients with similar outcome, and 3) within populations of surgeons with similar expertise levels.\\

+//Analysis of procedural aspects.//

+We manually define steps and phases of the operation from the synchronized video using an onthology previously established with the help of gynecologist surgeons. We then analyze the procedure using surgical workflow related metrics. Different metrics are computed including global DTW based distance, local NLTS, and pattern based distance. Following the same approach than for the first aim, from these metrics classification and machine learning approaches are then used to identify similar patterns 1) within populations of patients with similar clinical characteristics, 2) within populations of patients with similar outcome, and 3) within populations of surgeons with similar expertize levels.
