    LASANA: Laparoscopic Skill Analysis and Assessment video dataset
    (Technische Universität Dresden, 2025-12-26) Funke, Isabel; Bodenstedt, Sebastian; von Bechtolsheim, Felix; Oehme, Florian; Maruschke, Michael; Petzsch, Stefanie; Weitz, Jürgen; Distler, Marius; Mees, Sören Torge; Speidel, Stefanie
    The LASANA video dataset comprises 1270 trimmed and synchronized stereo video recordings of four basic laparoscopic training tasks (peg transfer, circle cutting, balloon resection, and suture & knot). Per task, there are at least 311 recordings in the dataset. Each recording is annotated with a structured skill rating, aggregated across three independent raters, as well as binary labels indicating the presence or absence of task-specific errors (for example, dropping an object during the peg transfer task, or puncturing the inner balloon during the balloon resection task). The LASANA video dataset is intended to support the development and evaluation of methods for automatic video-based laparoscopic skill analysis. For benchmarking, a fixed datasplit into training, validation, and test videos is provided for each task.
