Lower body mass index (BMI) and female sex are linked to higher incomplete colonoscopy rates. Improving pain management and procedure scheduling can enhance colonoscopy completion success.
Area of Science:
- Gastroenterology
- Endoscopy
- Public Health
Background:
- Incomplete colonoscopies present a challenge in colorectal cancer screening.
- Patient factors significantly influence procedure success rates.
- Optimizing colonoscopy techniques is crucial for diagnostic yield.
Purpose of the Study:
- To identify factors contributing to incomplete colonoscopies, focusing on Body Mass Index (BMI).
- To evaluate the effectiveness of second-line investigations for cancer detection.
- To assess the success rate of repeat colonoscopies.
Main Methods:
- Retrospective review of 2891 colonoscopies (August 2015 - July 2016).
- Analysis of 148 incomplete procedures and 148 complete procedures (BMI comparison).
- Inclusion of patient demographics, BMI, failure causes, referral modes, and second-line investigations.
Main Results:
- Lower BMI correlated with increased colonoscopy failure rates.
- Female patients exhibited higher failure rates (81%), often due to intolerance.
- Re-scoping success rate in experienced hands reached 95%.
Conclusions:
- Lower BMI and female sex are significant factors for incomplete colonoscopies.
- Strategies like enhanced pain management and balanced patient lists may improve outcomes.
- Repeat colonoscopies are highly successful in experienced settings.
