Validation of the parkland grading scale in predicting the critical view of safety during laparoscopic cholecystectomy: A prospective cohort study with implications for future artificial intelligence ground truth establishment

Key Points

• This research aims to validate the Parkland grading scale in predicting critical view of safety during laparoscopic cholecystectomy.
• Conducted a prospective cohort study
• Evaluated PGS scores during cholecystectomy procedures
• Established a standardized dataset for analysis
• A PGS score of ≥ 4 correlates with a significant risk of CVS failure
• Safer bail-out strategies were identified
• Created a dataset for training autonomous surgical risk assessment models
