Brief Summary

Previous researches demonstrated that a prepackaged low-residue diet (LRD) could achieve better bowel preparation quality compared with a self-prepared LRD. However, up to now, there has been no widely acceptable standard of LRD for bowel preparation. Moreover, these prepackaged LRD adopted in previous studies mainly consisted of traditional foods without further processing. Recently, a prepackaged LRD for Special Medical Purpose was specifically designed for bowel preparation. This trail was to compare the impact of the prepackaged LRD on bowel preparation for colonoscopy with self-prepared LRD by patients.

Outcome Measures

Primary Outcomes (2)

  • Adequate bowel preparation rate

    Boston Bowel Preparation Scale (BBPS) was adopted to evaluate the quality of bowel preparation. Each section of the colon (i.e. the right, the transverse, and the rectosigmoid colon) was rated (0, very poor; 1, poor; 2, good; and 3, very good). Adequate bowel of bowel preparation was defined as a total score ≥ 6 and all colon segments BBPS ≥ 2. Inadequate bowel preparation was defined as any colon segment BBPS ≤ 1.

  • BBPS scores of the entire colon

    The sum of the scores of three bowel segment.

Study Arms (2)

prepackaged Low-residue diet group

EXPERIMENTAL

The prepackaged Low-residue diet (Maifu Nutrition Technology Co. Ltd, Beijing, China). One package of the prepackaged Low-residue diet contained quantity of heat amounts to 268 kilocalories with 12.0 g of protein, 9.6 g of lipid, and 34.1 g of carbohydrate.

Dietary Supplement: Prepackaged Low-residue diet

self-prepared Low-residue group

ACTIVE COMPARATOR

Subjects in the self-prepared Low-residue diet group were instructed to follow and prepare an Low-residue diet in the day prior to colonoscopy

Dietary Supplement: Self-prepared Low-residue diet

Interventions

Subjects in the prepackaged Low-residue diet group were given 6 packs (60g/pack) pre-packaged formula LRD and asked to use the formula according to individual needs prior to colonoscopy.
