| description | High-quality bowel preparation is an important prerequisite for a successful colonoscopy.
However, older patients with constipation are at high risk for inadequate bowel
preparation. This study aimed to evaluate the effectiveness of an abdominal vibration
combined with walking exercise (AVCWE) programme compared with walking exercise
(WE) and standard bowel preparation regimens for bowel preparation in older patients
with constipation. A prospective, single-blinded, three-arm randomised controlled trial
was conducted between February and August 2023. Older patients with constipation who
underwent colonoscopy at a tertiary hospital in China were prospectively enrolled and
randomly assigned to one of the three groups: the AVCWE group, the WE group, or the
control group. During the period of laxative ingestion, patients assigned to the AVCWE
group were asked to walk independently for at least 5,500 steps at no more than moderate
intensity and received two cycles of moderate-intensity abdominal vibrations. Patients in
the WE group were required to walk independently for at least 5,500 steps at no more
than moderate intensity, whereas patients in the control group received only the standard
bowel preparation regimen. The primary outcome was the quality of bowel preparation
assessed by the Boston Bowel Preparation Scale (BBPS). The secondary outcomes
included adenoma detection rate, caecal intubation rate, caecal intubation time, adverse
events, satisfaction, and willingness to repeat the same preparation. Additionally, logistic
regression analysis was performed to identify risk factors for inadequate bowel
preparation. A total of 271 patients were randomly divided into AVCWE group (n = 90),
WE group (n = 90), and control group (n = 91). The total BBPS score in the AVCWE group (M = 6.99, SD = 0.93) was significantly higher compared with both the WE group
(M = 6.58, SD = 1.08) and the control group (M = 5.96, SD = 1.14) (p < 0.001). Similarly,
compared with other groups, the AVCWE group also had significant advantages in
improving adenoma detection rate (AVCWE group vs WE group vs control group: 42.2%
vs 24.4% vs 20.9%, p = 0.003), satisfaction score (91.98 [SD = 5.93] vs 89.39 [SD = 7.48]
vs 87.37 [SD = 8.25], p < 0.001) and reducing the incidence of bloating (22.2% vs 38.9%
vs 40.7%, p = 0.016). However, there were no significant differences in caecal intubation
rate, caecal intubation time, and willingness. Besides, the first colonoscopy (OR, 2.329;
95% CI, 1.210–4.485; p = 0.011), laxative use ≥ 3 times per week (OR, 2.675; 95% CI,
1.452–4.931; p = 0.002), and poor dietary compliance (OR, 2.249; 95% CI, 1.142–4.430;
p = 0.019) were found to be significant predictors of inadequate bowel preparation in
older patients with constipation. The AVCWE programme significantly improved the
quality of bowel preparation, adenoma detection rate, satisfaction, and significantly
reduced the incidence of bloating in older patients with constipation. Healthcare providers
are recommended to adopt this strategy to optimise the detection of colorectal diseases
and elevate the standard of healthcare services for this ‘difficult-to-prepare’ population.
