Females exhibit superior bowel preparation during colonoscopies compared to males, achieving higher Boston Bowel Preparation Scores (BBPS). However, male patients experienced longer colonoscopy insertion and withdrawal times, indicating significant sex-based differences in the procedure.
Area of Science:
- Gastroenterology
- Endoscopy
- Clinical Research
Background:
- Colon length and cancer morphology exhibit known sex-based variations.
- Previous research suggests potential differences in colonoscopy outcomes between sexes.
Purpose of the Study:
- To investigate sex differences in Boston Bowel Preparation Score (BBPS).
- To examine sex disparities in colonoscopy insertion and withdrawal times.
Main Methods:
- Retrospective analysis of 12,561 patients' colonoscopy records (March 2015-April 2018).
- Evaluation of colon cleanliness using BBPS.
- Statistical comparison of demographic, clinical, and procedural variables between sexes.
Main Results:
- Females demonstrated significantly better bowel preparation than males (mean BBPS: 7.4 vs. 7.2, p=0.001).
- Males had longer cecal intubation times (8.3 min vs. 6.2 min, p<0.001) and withdrawal times (7.9 min vs. 7.4 min, p<0.001).
Conclusions:
- Significant sex differences exist in BBPS, cecal intubation, and withdrawal times during colonoscopy.
- These findings highlight the importance of considering sex in colonoscopy quality assessment and procedural efficiency.
