Multicenter prospective evaluation of the express view reading mode for small-bowel capsule endoscopy studies

Area of Science:

• Gastroenterology
• Medical Imaging
• Artificial Intelligence

Background:

• Capsule endoscopy is crucial for diagnosing obscure gastrointestinal bleeding.
• Reducing the interpretation time of capsule endoscopy videos is a clinical priority for gastroenterologists.
• The Intromedic capsule system's "express view" reading mode was evaluated.

Purpose of the Study:

• To prospectively evaluate the efficacy of the "express view" reading mode in reducing capsule endoscopy interpretation time.
• To assess the diagnostic accuracy and sensitivity of the "express view" mode compared to standard reading.
• To determine the impact of the express view algorithm on clinical workflow.

Main Methods:

• A prospective, multicenter study included 83 patients with obscure gastrointestinal bleeding.
• Small-bowel capsule endoscopy was performed using the Intromedic system.
• Films were read in standard mode, followed by express view mode at a separate center, with expert consensus as the gold standard.

Main Results:

• Express view mode reduced mean reading time from 39.7 to 19.7 minutes (P < 1x10^-4).
• Sensitivity for detecting significant lesions was 93.3% for standard and 82.2% for express view (not significant).
• The informatics algorithm detected 94.3% of significant images, missing only four cases of small-bowel angiodysplasia.

Conclusions:

• The express view algorithm significantly shortens Intromedic capsule film reading time.
• This AI-driven approach demonstrates high sensitivity for lesion detection.
• Express view offers a valuable tool for efficient gastroenterological practice.
