Objective:

To assess whether computer vision can improve the signal-to-background ratio (SBR) of indocyanine green near-infrared fluorescence (ICG-NIRF) for identifying extrahepatic biliary ducts during laparoscopic cholecystectomy, and to demonstrate feasibility of combining ICG-NIRF with white-light imaging.

Approach:

• Study rationale: The authors hypothesized that attenuating background liver fluorescence would improve detection of biliary structures and explored a multimodal computer-vision method to highlight ducts while retaining white-light anatomical context.
• Video dataset: A multi-institutional database contained 928 adult and pediatric laparoscopic cholecystectomy videos collected from January 2019 through March 2025. ICG-NIRF was used in 156 cases.
• Frame selection: Eligible videos showed the gallbladder and extrahepatic ducts with biliary fluorescence and minimal blur or camera instability. Screening yielded 487 clips; frames were extracted at two per second.

Key Findings:

• The supplied context describes the study rationale and initial data-processing methods but does not provide quantitative results.
• The authors propose a computer-vision fusion image that selectively enhances extrahepatic ducts in ICG-NIRF while preserving surrounding white-light anatomy.

Interpretation:

The study is designed to address background fluorescence and subjective interpretation that can limit ICG-NIRF visualization. The provided context establishes the hypothesis and technical aim, but does not report whether the method improved SBR or clinical outcomes.

Limitations:

• The supplied article context ends during the methods section and does not include the full methods, results, or discussion.
• No quantitative performance measures, validation details, or clinical outcome data are provided in the supplied context.

Conclusion:

The authors describe a computer-vision approach intended to improve ICG-NIRF biliary visualization and combine it with white-light anatomical context; its effectiveness cannot be determined from the provided material.
