The investigators evaluated colonoscopy in octogenarians (age ≥ 80 years), and reported their results in the July issue of the American Journal of Gastroenterology.
They prospectively determine differences between octogenarians and nonoctogenarians in adequacy of colonic preparation, success in completing colonoscopy, and complications of conscious sedation.
A total of 250 consecutive outpatients (150 nonoctogenarians and 100 octogenarians), referred for colonoscopy, were included in the study.
Colonic preparation tolerance was assessed before colonoscopy, and the success rate and preparation were evaluated after the procedure.
In addition, conscious sedation complications were compared.

In octogenarians and nonoctogenarians, preparation tolerance (86% and 90%, respectively) was similar.
The authors found that the endoscopic success rate was slightly lower in octogenarians (90% vs 99%).
Furthermore, preparation was poor in 16% of octogenarians, compared with 4% of nonoctogenarians. This was independent of the type of preparation used.
Oxygen desaturation was more common in octogenarians (27% vs 19%) and associated with a higher meperidine dose (1.05 vs 0.75 mg/kg).
No adverse outcomes occurred in either study group.
Dr Frank J. Lukens, of the Mayo Clinic, Jacksonville, Florida, concluded on behalf of his group, "Colonic preparations were well tolerated and colonoscopic success rates were high in octogenarians and nonoctogenarians.
"However, poor colonic preparation was 4-times as likely in octogenarians and was the most important impediment to adequate colonoscopy."
