We are very delighted to inform you that the Cholec80 dataset is now available. The Cholec80 dataset contains 80 videos of cholecystectomy procedures recorded at University Hospital of Strasbourg/IRCAD (Strasbourg, France). All the frames are fully annotated with 7 defined phases: (1) preparation, (2) calot triangle dissection, (3) clipping and cutting, (4) gallbladder dissection, (5) gallbladder packaging, (6) cleaning and coagulation, and (7) gallbladder retraction. This dataset also contains tool annotations (generated at 1 fps) indicating the presence of seven tools in an image. The seven tools are: grasper, bipolar, hook, scissors, clipper, irrigator, and specimen bag.

We would like to remind you that this dataset could only be generated thanks to the continuous support from the surgeons from our partner hospital. In order to properly credit them for their efforts, you are kindly requested to cite the paper that led to the generation of this dataset:
