Factors Associated With Shorter Colonoscopy Surveillance Intervals for Patients With Low-Risk Colorectal Adenomas and Effects on Outcome
View abstract on PubMed
Summary
This summary is machine-generated.Endoscopists often shorten surveillance for low-risk adenomas (LRAs) due to patient factors, but this does not improve follow-up outcomes. Current guidelines recommending 5-year surveillance for LRAs are supported by these findings.
Area Of Science
- Gastroenterology
- Oncology
- Preventive Medicine
Background
- Guidelines recommend 5-10 year surveillance for low-risk adenomas (LRAs).
- Endoscopists frequently deviate from guidelines, recommending shorter surveillance intervals for LRAs.
- Reasons for shorter surveillance and impact on outcomes are not well understood.
Purpose Of The Study
- To identify factors influencing endoscopists' recommendations for shorter surveillance intervals in patients with LRAs.
- To determine if shorter surveillance intervals impact outcomes at follow-up colonoscopies.
Main Methods
- Analysis of data from 1560 participants in a prospective chemoprevention trial with LRAs.
- Collected data on participant and endoscopist characteristics and index/follow-up colonoscopy findings.
- Compared outcomes between 3-year and 5-year surveillance intervals.
Main Results
- 38.1% of subjects with LRAs received a 3-year surveillance recommendation.
- Factors associated with 3-year intervals included African American race, Asian/Pacific Islander ethnicity, multiple adenomas, serrated polyps, and poor bowel preparation quality.
- No significant differences in adenoma or serrated polyp detection rates were observed between 3-year and 5-year surveillance groups.
Conclusions
- Endoscopists frequently recommend shorter surveillance intervals for LRAs based on various factors.
- Shorter surveillance intervals did not lead to improved detection of adenomas or serrated polyps at follow-up.
- Findings support current guidelines recommending at least 5-year surveillance for individuals with LRAs.
