Weight-loss drug before hernia surgery cuts complications in obese patients
NCT ID NCT07638592
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a 16-week weight-loss program using the drug tirzepatide before elective hernia surgery in 91 adults with obesity. Participants lost an average of 13.8% of their body weight, and all reached the target weight needed for surgery. Compared to a similar group who had surgery without the drug, those who took tirzepatide had fewer wound problems after the operation.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Adults (≥ 18 years) with obesity (BMI ≥ 30 kg/m²) and an elective primary ventral or incisional midline hernia of European Hernia Society width W2-W3, amenable to a standard Rives-Stoppa retromuscular repair, managed at four high-volume abdominal wall surgery units. The prospective prehabilitation cohort comprises consecutive eligible patients who agreed to undergo a structured 16-week tirzepatide-based preoperative weight-optimization program before elective repair. The comparative control cohort comprises patients meeting the same age, BMI, hernia type, EHS width, and surgical-technique criteria who underwent elective repair without pharmacologic prehabilitation at the same centers over the preceding five years, identified from prospectively maintained institutional databases. Patients requiring emergency surgery, posterior component separation/transversus abdominis release, or with contraindications to tirzepatide were not included.
