๐ Background
Biliary strictures can be challenging to classify as either benign or malignant, and traditional sampling techniques often yield poor accuracy. The advent of AI technology in medical diagnostics offers a new avenue for improving classification accuracy, potentially transforming how biliary conditions are assessed and managed.
๐๏ธ Study
The SMART-AI trial was a single-center, prospective study aimed at evaluating the effectiveness of a real-time cholangioscopy AI system. The AI was designed to analyze video streams from cholangioscopy procedures in real-time, providing immediate classification of biliary strictures and allowing for a direct comparison with traditional sampling methods and human observers.
๐ Results
The results were compelling: the AI achieved an impressive 87.8% accuracy in classifying biliary strictures, significantly outperforming standard sampling techniques, which had an accuracy of only 67.4%. Furthermore, the AI’s performance surpassed that of both junior-level (61.5%) and experienced endoscopists (63.1%), highlighting the potential of AI to enhance diagnostic capabilities in this field.
๐ Impact and Implications
The implications of this study are profound. By demonstrating that AI can provide more accurate classifications of biliary strictures, we may be on the brink of a new era in diagnostic medicine. This technology could lead to better patient management, reduced need for invasive procedures, and ultimately improved outcomes for patients with biliary conditions. The integration of AI into clinical practice could revolutionize how we approach diagnostics in gastroenterology.
๐ฎ Conclusion
The SMART-AI trial underscores the transformative potential of artificial intelligence in the classification of biliary strictures. With its superior accuracy compared to traditional methods and human observers, AI could play a crucial role in enhancing diagnostic precision and patient care. Continued research and development in this area are essential to fully realize the benefits of AI in healthcare.

Classification of biliary strictures using real-time cholangioscopy artificial intelligence: the SMART-AI trial.
Abstract
BACKGROUND: Sampling techniques have poor accuracy for classifying biliary strictures as benign or malignant. Previously, a cholangioscopy artificial intelligence (AI) outperformed sampling techniques based solely on analysis of previously recorded cholangioscopy footage.
OBJECTIVE: The aim of this single-center, prospective trial was to compare the performance of a real-time cholangioscopy AI to both sampling techniques and human observers for the task of biliary stricture classification.
DESIGN: A cholangioscopy AI computer connected directly to a cholangioscope console. The computer analyzed the cholangioscopy video stream during procedures for suspected biliary strictures. The primary outcome of the study was comparison of the performance of cholangioscopy AI to sampling techniques – brush cytology and transpapillary forceps biopsy – for biliary stricture classification. Secondary outcomes included comparison of the AI classification performance to that of 14 human observers (separated into junior-level and experienced-level cohorts) who reviewed the cholangioscopy footage.
RESULTS: A total of 41 patients were enrolled in the trial and had biliary strictures analyzed by cholangioscopy AI. For the classification of strictures, the AI had greater classification accuracy than standard sampling techniques (87.8% versus 67.4%; p = 0.043). Additionally, the cholangioscopy AI was significantly more accurate for biliary stricture classification than both junior-level (87.8% versus 61.5%; p = 0.001) and experienced endoscopists (87.8% versus 63.1%; p = 0.011).
CONCLUSION: This trial demonstrates that sampling techniques and human assessment of biliary strictures are flawed and there may be a benefit to the use of a cholangioscopy AI system to aid in biliary stricture classification.
