Computer-Aided Detection Improves Adenomas per Colonoscopy for Screening and Surveillance Colonoscopy: A Randomized...

Area of Science:

• Gastroenterology
• Medical Devices
• Colorectal Cancer Screening

Background:

• Colonoscopy quality is crucial for effective colorectal cancer screening.
• Endoscopist variability impacts colonoscopy efficacy.
• Computer-aided detection (CADe) devices offer potential quality improvements.

Purpose of the Study:

• To evaluate the clinical benefit and safety of CADe devices in colonoscopy.
• To assess the impact of CADe on adenoma detection rates.
• To determine if CADe affects the resection of non-neoplastic lesions.

Main Methods:

• Prospective randomized study at 5 US centers.
• Inclusion of board-certified gastroenterologists (n=22) and participants aged ≥40.
• Primary endpoints: adenomas per colonoscopy (APC) and true histology rate (THR).

Main Results:

• CADe use significantly increased APC (0.83 vs 1.05, P=.002).
• No significant decrease in THR observed with CADe (71.7% vs 67.4%, P<.001).
• Adenoma detection rate showed a trend towards improvement with CADe (43.9% vs 47.8%, P=.065).

Conclusions:

• CADe devices statistically improve adenoma detection in screening colonoscopies.
• CADe use does not increase the resection of non-neoplastic lesions.
• CADe is a safe and effective tool for enhancing colonoscopy quality.
