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: = 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: < 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.
