Real-time AI labeling of critical anatomy during laparoscopic gallbladder removal
Research on Identifying Critical Surgical Anatomy in Cholecystectomy Videos Based on Deep Learning
This project will try a real-time AI algorithm to label key anatomical structures in laparoscopic cholecystectomy videos to help surgeons avoid bile duct injuries.

What this trial studies
This observational project collects high-quality laparoscopic cholecystectomy videos from several participating hospitals and uses them to train a deep-learning object recognition algorithm. The model is trained to identify and label key anatomical structures in video frames and to highlight areas considered dangerous or safe during dissection. Blurry or out-of-hospital videos are excluded to preserve data quality, and annotated frames are used for model validation. The goal is to produce real-time visual guidance that can be integrated into the operating room workflow for further clinical testing.
Who should consider this trial
Good fit: Adults aged 18 or older who are scheduled for laparoscopic cholecystectomy at one of the participating hospitals and whose operations are recorded with clear intraoperative video are the intended data sources.
Not a fit: Patients who undergo open cholecystectomy, have surgery performed outside the participating centers, or whose intraoperative videos are too blurry will likely not benefit from this project.
Why it matters
Potential benefit: If successful, the algorithm could give surgeons immediate visual warnings during gallbladder removal, potentially reducing bile duct injuries and other complications.
How similar studies have performed: Similar deep-learning approaches for surgical phase recognition and anatomy segmentation have shown promising early results in research settings but are not yet widely adopted in routine clinical practice.
