Abstract:
Objective:To analyze the characteristics of colonoscopy in patients aged 75 and above.Methods:The clinical data of 216 elderly patients aged 75 and above undergoing colonoscopy in our hospital from August 2015 to June 2019 were retrospectively analyzed. According to WHO criteria, there were 140 cases in aged group (75 to 89 years old) and 76 cases in the advanced aged group (90 years old and over). Demographic data, colonoscopy completion rate, bowel preparation quality, positive diagnosis rate and adverse events were analyzed and compared between the two groups.Results:More colonoscopies were performed under general anesthesia [7.9% (6/76) vs. 1.4% (2/140), χ 2=5.775, P<0.05] in the advanced aged group compared to the aged group, and the advanced aged group received lower doses of propofol and fentanyl when colonoscopies were administered with moderate sedation [(69.0±37.4) mg vs.(100.8±34.3)mg, t=6.302, P<0.01; (57.5±31.2) μg vs. (84.0±28.6)μg, t=6.297, P<0.01]. Colonoscopy completion was lower in the advanced aged group than that in the aged group[88.2%(67/76) vs. 99.3% (139/140), χ 2=13.815, P<0.01] and bowl preparation quality was worse [31.6%(24/76) vs. 15.0% (21/140), χ 2=8.209, P<0.05]. The proportion of adverse cardiopulmonary events [5.3%(4/76) vs. 0 (0/140), χ 2=7.507, P<0.01] and overall adverse events [9.2% (7/76) vs. 0.7% (1/140), χ 2=9.970, P<0.01] were higher in the advanced aged group than those in the elderly group. Colorectal cancer [14.5% (11/76) vs. 2.1% (3/140), χ 2=12.357, P<0.01] and advanced adenoma [27.6% (21/76) vs. 6.4% (9/140), χ 2=18.516, P<0.01] were more common in the advanced aged group than those in the aged group. Conclusion:Compared with the patients aged 75-89 years, patients aged 90 years and above have lower percentage of colonoscopy completion, lower quality of bowl preparation, and higher incidence of adverse events, and higher percentage of colorectal cancer and advanced adenomas detected.
