The superiority of one-day dietary preparation over three-day dietary preparation for high-intensity focused ultrasound treatment: a retrospective study.

OBJECTIVE

To compare dietary preparation durations and evaluate optimal diet types before high-intensity focused ultrasound (HIFU) treatment.

MATERIALS AND

METHODS

Five hundred patients with uterine fibroids or adenomyosis undergoing HIFU were enrolled. Initially, 300 patients were randomized to 3-day, 2-day, or 1-day dietary preparation (n = 100 each) to compare enema frequency, intestinal gas volume, comfort scores, and compliance. Subsequently, the 1-day group (Group A, clear liquid diet) was compared with 200 additional patients assigned to Group B (semiliquid diet) or Group C (low-residue diet) regarding intestinal cleansing efficacy, comfort scores, serum electrolyte changes, and physical recovery.

RESULTS

No significant differences were observed in enema frequency or intestinal gas volume among the three duration groups (p > 0.05); however, the 1-day group demonstrated superior comfort scores (p < 0.05). Within 1-day preparation, the low-residue diet group exhibited higher comfort scores, reduced intestinal gas volume, and better compliance compared to clear liquid and semiliquid diets (p < 0.05).

CONCLUSIONS

One-day dietary preparation is superior to three-day preparation for bowel cleansing before HIFU. Low-residue diet effectively meets clinical bowel cleansing requirements while achieving high patient acceptability. We recommend one-day low-residue diet as the preferred bowel preparation protocol for patients undergoing HIFU treatment.
