What this trial studies

This randomized controlled trial aims to compare the effects of a preoperative intensive weight management program against immediate surgery for obese patients undergoing complex abdominal wall reconstruction. Participants will be randomly assigned to either a 6-month medical weight loss program or to receive surgery without prior weight loss. The study will assess the quality of life specific to abdominal wall conditions using the HerQLes survey to determine if the surgical outcomes are comparable between the two groups. Conducted at Cleveland Clinic, the program will involve a team of specialists in weight loss medicine.

Who should consider this trial

Good fit: Ideal candidates are adults with a BMI between 40-55 kg/m2 who require open retromuscular ventral hernia repair and are not pursuing weight loss surgery.

Not a fit: Patients who are not fluent in English, have urgent repair needs, or have a BMI outside the specified range will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and quality of life for obese patients undergoing abdominal wall reconstruction.

How similar studies have performed: Other studies have shown promising results with preoperative weight management in surgical outcomes, suggesting this approach may be beneficial.
