Is this trial a fit for you?

Likely a good fit

Adults with BMI ≥30 scheduled for open or minimally invasive liver resection who can understand Swedish, Norwegian, Danish, or English.

Probably not a fit

Patients not experiencing reduced complications or bleeding from the LCD, or those not adhering to the regimen, may not see benefit.

What this trial studies

This multicenter, open-label randomized trial tests whether a short preoperative low calorie diet reduces intraoperative blood loss and postoperative morbidity in adults undergoing liver resection. Participants with BMI of 30 or higher are randomized to a 7-day LCD or standard prep. The study builds on a prior small trial and aims to enroll enough patients to analyze postoperative complications using the Comprehensive Complication Index. Primary outcome is postoperative complications; secondary outcomes include blood loss, surgery duration, hospital stay, margin status, inflammatory response, adherence, and quality of life.

Why it matters

Potential benefit: If successful, the diet could reduce surgical bleeding and complications, potentially improving recovery after liver surgery.

How similar studies have gone: A prior small single-center randomized trial suggested reduced blood loss and fewer complications, but this larger multicenter trial tests the approach more definitively.
