Summary
Colonoscopy preparation is adequate in most older adults, but poor preparation is more common in octogenarians. This impacts colonoscopy success rates in the elderly population.
Area of Science:
- Gastroenterology
- Geriatric Medicine
- Endoscopy
Background:
- Increasing number of octogenarians undergoing colonoscopy.
- Previous studies report poor colonoscopy completion and preparation in this age group.
- Need for prospective data to clarify age-related differences.
Purpose of the Study:
- Prospectively compare octogenarians and non-octogenarians.
- Evaluate differences in colonic preparation adequacy.
- Assess colonoscopy completion success rates.
- Compare conscious sedation complications.
Main Methods:
- Prospective cohort study.
- 250 outpatients (100 octogenarians, 150 non-octogenarians).
- Assessed preparation tolerance, success, and complications.
Main Results:
- Similar preparation tolerance between groups (86% vs 90%).
- Lower endoscopic success in octogenarians (90% vs 99%).
- Poor preparation more frequent in octogenarians (16% vs 4%).
- Increased oxygen desaturation in octogenarians (27% vs 19%).
Conclusions:
- Colonoscopy preparation is generally well-tolerated in octogenarians.
- Poor preparation is a significant impediment to adequate colonoscopy in the elderly.
- While success rates are high, octogenarians face challenges with preparation quality.
