Can we shorten the small-bowel capsule reading time with the "Quick-view" image detection system?

Area of Science:

• Gastroenterology
• Medical Imaging
• Artificial Intelligence in Medicine

Background:

• Small-bowel capsule endoscopy (SBCE) interpretation is time-consuming, with a mean reading time of approximately 60 minutes.
• Reducing SBCE reading time is a critical objective for improving workflow efficiency.

Purpose of the Study:

• To evaluate the diagnostic efficiency and performance of the "Quick-view" detection algorithm for small-bowel capsule endoscopy.
• To assess the impact of the Quick-view algorithm on reading time and accuracy.

Main Methods:

• A multicentre prospective comparative study involving 106 small-bowel capsule endoscopy procedures.
• Twelve experienced readers reviewed capsule films using the Quick-view mode.
• Reading time, image relevance, and concordance with initial readings were analyzed, with discordant results reviewed by experts.

Main Results:

• The mean reading time using Quick-view mode was significantly reduced to 11.6 minutes.
• Concordant negative and positive results were achieved in 38.6% and 33.0% of cases, respectively.
• The Quick-view algorithm demonstrated a theoretical sensitivity of 93.5% for detecting significant lesions.

Conclusions:

• The Quick-view algorithm effectively detects nearly 94% of significant lesions in small-bowel capsule endoscopy.
• Quick-view reading is as efficient as initial reading methods but substantially shorter.
• Further studies are recommended, but results suggest excellent sensitivity for the Quick-view algorithm.
