Anesthesia Assistance in Colonoscopy: Impact on Quality Indicators

Area of Science:

• Gastroenterology
• Endoscopy
• Cancer Screening

Background:

• Adenoma detection rate (ADR) and polyp detection rate (PDR) are key colonoscopy quality metrics.
• Improving ADR/PDR is crucial for reducing colorectal cancer (CRC) incidence and mortality.
• Previous studies on factors influencing ADR/PDR are limited.

Purpose of the Study:

• To evaluate the impact of anesthesia assistance (AA) on ADR and PDR.
• To identify risk factors affecting ADR and PDR during colonoscopy screening.

Main Methods:

• Retrospective study of 7170 patients undergoing colonoscopy (May 2019-August 2020).
• Comparison of ADR and PDR between patients with (Group A) and without (Group O) AA.
• Propensity score matching (PSM) and binary logistic regression used for analysis.

Main Results:

• No significant difference in ADR or PDR between groups with and without AA after PSM (736 patients per group).
• Independent risk factors for ADR included endoscopic device version, image-based technique, and image count.
• Independent risk factors for PDR included age, gender, high-risk status, endoscopist seniority, image-based technique, and image count.

Conclusions:

• Anesthesia assistance does not influence ADR or PDR in colonoscopies.
• While AA may improve patient satisfaction, it is not necessary for enhancing colonoscopy quality.
• Endoscopists should focus on optimizing device, technique, and considering patient factors for improved detection.
