Colonoscopy in the elderly

Abstract

An evaluation of the utility, morbidity, and patient tolerance of colonoscopy in elderly (> or = 70 years) patients was undertaken and compared to data for a similar group of younger patients (50-70 years) who underwent colonoscopy during the same 48 months. Data reviewed for both groups included demographics, indications for colonoscopy, effectiveness of bowel preparation, colonoscopy completion, endoscopic findings, and complications. The mean age of the entire 656-patient population was 69 +/- 10 years; 87 (25%) of the 354 elderly patients were greater than 80 years of age and the average age of the 302-member control group was 59.8 +/- 5.8 years. Indications for colonoscopy were the same in both groups and included rectal bleeding, 134 (20%); prior colorectal operation, 115 (18%); a history of adenomatous polyps, 82 (12%); guaiac-positive stools, 49 (8%); abnormal finding on barium enema, 19 (3%); and miscellaneous other gastrointestinal symptoms, 151 (23%). Screening colonoscopy was performed in 106 (16%). Colonoscopy was successfully completed to the cecum or the ileocolic anastomosis in 85% (555/656) of the entire population. Only 78% (275/354) of elderly patients had colonoscopy successfully completed compared to 93% (281/302) of their younger counterparts (P = 0.001). Elderly patients were significantly more likely to have an abnormality than younger patients (74% vs 60%, P < 0.05). Malignant colorectal neoplasia was more common in the elderly (6% vs 2%, P = 0.03); however, benign neoplasia was equally present in both age groups (30% vs 27%, P = NS).(ABSTRACT TRUNCATED AT 250 WORDS)

A Matched Case-Control Study Using the Propensity Score on Differences in the Characteristics of Colorectal Polyps between Younger and Older Koreans: Proximal Shift in the Distribution of Colorectal Polyps among Older Koreans

“…Several reports on the findings of colonoscopy among older individuals support these findings. 16,28 The results of this study showed that 32.3% of the young had colorectal polyps detected by total colonoscopy, and 53.3% of the older patients had colorectal polyps detected (χ 2 test, p＜0.001). However, the proportion of adenomas among the colorectal polyps in the young patients was comparable to the older patients as shown in Table 4 (64.0% vs 68.9%, p=0.310).…”

A felső és alsó endoszkópiák indikációja, a diagnózisok megoszlása és minőségi mutatók 2010–2011-ben a Semmelweis Egyetem I. Belgyógyászati Klinikáján

“…Az 50 év feletti aszimptómás betegcsoportokban végzett screening kolonoszkópiák kevesebb mint 1%-ában fordul elő vastagbélrák [38,39]. Jelentősen magasabb gyakoriságokat (3,3%-7,1%) kö-zölnek olyan tanulmányok, amelyekben szimptómás, fennjáró, illetve kórházi bennfekvő betegek egyaránt szerepelnek [35,40,41]. Az általunk megfigyelt 6,9%-os előfordulási gyakoriság igen magasnak tekinthető, azonban megfelel más, hasonlóan idős, polimorbid betegeket nem kizáró betegpopulációjú vizsgálatok adatainak [40,41].…”
