Comparison of Polyp Detection and False Alarm Rates in Water Exchange and Air Insufflation Colonoscopy

NCT04727814 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 250

Last updated 2021-04-05

No results posted yet for this study

Summary

Water exchange (WE) improves adenoma detection rate (ADR) but missed polyps occur due to human limitations. Computer-aided detection (CADe) improves polyp detection and can overcome human omissions, but a limiting factor is feces and air bubbles related false alarms (FA). WE provides salvage cleansing and can potentially reduce FA. The investigators compared the additional polyp detection rate (APDR) and false alarm rate (FAR) by CADe between WE and air insufflation.

Conditions
