体位联动式大肠水疗在习惯性便秘患者肠镜前肠道准备中的应用价值

Objective To investigate the effect of position-linked colonic hydrotherapy on bowel preparation quality in patients with habitual constipation. Methods Ninety-two patients from February 2025 to June 2026 were randomly assigned to position-linked group(experimental group)(n=46) or left lateral position group(control group)(n=46). Boston Bowel Preparation Scale(BBPS) score, hydrotherapy duration, fluid volume, adverse reactions, Cleveland Clinic Constipation(CCS) score, satisfaction, and compliance were compared. Planned sample size was 120. This is an interim analysis(76.7%). Results BBPS total score was significantly higher in experimental group(6.37±1.77) than the control group(5.43±2.19)(P=0.027). RC segment score was higher(1.96±0.67 vs. 1.65±0.79, P=0.049). LC segment score was higher(2.11±0.74 vs. 1.76±0.82, P=0.035). TC segment score showed a numerical trend(2.30±0.73 vs. 2.02±0.88) without reaching statistical significance(P=0.097). There were no statistically significant differences between the two groups regarding treatment duration, total fluid volume administered, incidence of adverse reactions, satisfaction, and compliance(P>0.05). Conclusion Position-linked colonic hydrotherapy significantly improves bowel preparation quality with notable increase in BBPS score and RC/LC colonic segment cleanliness. It is worthy of clinical promotion.
