Advanced Laparoscopic Assessment (ALA)

Objective skill assessment of surgical trainees using artificial intelligence

Swiss-MIS supports the ALA project. Developed at the Department of Visceral Surgery and Medicine at Inselspital Bern in cooperation with ARTORG Center for Biomedical Engineering Research at the University of Bern, this project aims to establish a web-based platform using artificial intelligence to standardize and automate skill assessment of surgical trainees by analysis of laparoscopic videos.

At a first stage, and for the moment, the ala.surgery platform is operative as a personal video archive. Swiss-MIS members, can actually upload and securely store and share at will their videos in a very user’s friendly way.

At a second stage, after implementing and validating the artificial intelligence algorithms, videos can be uploaded and used for surgical skill assessment. The workflow will be as shown in the figure above.

Try the ala.surgery platform now! Upload and store your videos with a few simple steps.
