Summary
Inadequate bowel preparation is the only correctable factor impacting colonoscopy insertion time and patient comfort. Optimizing bowel prep improves procedure efficiency and patient experience.
Area of Science:
- Gastroenterology
- Endoscopy
- Clinical Research
Background:
- Successful colonoscopy requires cecal intubation, accurate observation, and patient comfort.
- Factors influencing colonoscopy insertion time and patient discomfort require investigation.
Purpose of the Study:
- To identify variables associated with colonoscopy insertion time.
- To determine factors linked to patient discomfort during colonoscopy.
Main Methods:
- Prospective analysis of 909 colonoscopies by a single endoscopist.
- Bowel cleansing with 4L Colonlyte; meperidine for sedation.
- Patient discomfort assessed via a 5-level Likert scale.
Main Results:
- Cecal intubation achieved in 96.4% of cases; mean insertion time 6.9 minutes.
- Inadequate bowel preparation, advanced age, and constipation correlated with prolonged insertion time.
- Female gender was associated with increased patient discomfort.
Conclusions:
- Unsatisfactory bowel preparation is the sole modifiable factor affecting colonoscopy insertion time and patient discomfort.
- Improving bowel preparation can enhance colonoscopy efficiency and patient tolerance.
