Study summary

The goal of this randomized controlled trial is to compare preoperative intensive weight management to upfront surgery in obese patients undergoing complex abdominal wall reconstruction. The main question is will abdominal wall specific quality of life (using the HerQLes survey) for the group undergoing upfront surgery be non-inferior compared to the group in the weight management program.

Read the detailed description

This is a prospective, single-center, registry-based, parallel, randomized controlled trial with 1:1 allocation. The study will consist of 2 arms: an intensive 6-month medical weight loss program prior to open retromuscular ventral hernia repair compared to upfront surgery without required weight loss. The medical obesity intervention will be conducted by physicians, nurse practitioners, and dieticians specializing in weight loss medicine. The study operations will be performed at Cleveland Clinic by six hernia surgeons with advanced abdominal wall reconstruction training.

Inclusion criteria

  • Adults having open retromuscular ventral hernia repair with an anticipated posterior component separation with transversus abdominis release and synthetic mesh
  • 40-55 kg/m2 and who are not planning to pursue weight loss surgery for any of the following reasons: they are not a candidate for weight loss surgery, cannot pursue weight loss surgery for insurance reasons, or are not interested in pursuing weight loss surgery.

Exclusion criteria

Exclusion criteria

  • Lack of English language fluency
  • Urgent need for repair as determined by surgeon judgement
  • Pregnant patients
  • Permanent stoma in place
  • Isolated flank hernia
  • Anticipated need for staged operation; for example, patients who will undergo a mesh excision separate from definitive reconstruction.
  • \<40 or >55 kg/m2
  • Inability to participate in the Obesity Management Program due to lack of insurance coverage or history of mental illness (including eating disorders, schizophrenia, etc.).
  • Obstructive symptoms
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Interventions

  • OtherPreoperative Weight Management Program

    The medical obesity intervention is comprised of monthly visits with an obesity medicine (OM) provider +/- a registered dietitian (in person or virtual). Lifestyle modifications (nutrition, physical activity, stress, sleep), appetite control, and medication side effects will be addressed in all visits. At initial visit, patients will evaluated in person by an OM provider +/- registered dietitian. An individualized intense lifestyle intervention will be implemented with the addition of an anti-obesity medication (phentermine, naltrexone/bupropion, phentermine/topiramate, liraglutide, semaglutide, etc). Medication use will be based on disease risk, patient preference, severity of obesity, contraindications, potential drug interactions and insurance coverage. A diet recommendation will be tailored to the patient's medical and food allergy history. Weight and vital signs will be monitored at each visit. Participants will have a total of 5 follow-up monthly encounters, every 30 +/- 7 days.

This study also gives Semaglutide. No intervention listed here names it: that was found by reading the record.

What researchers measure

Primary outcomes

  1. Abdominal core health-specific quality of life at 1 year

    This will be measured at 1 year using the HerQLes survey which is scored from 0-100 with higher scores indicating better quality of life.

    Time frame: 1 year

Secondary outcomes

  1. Hernia recurrence at 1 year

    Time frame: 1 year

  7. Patient-reported pain changes with preoperative weight management program

    This includes difference in pain using the PROMIS 3a Pain Intensity Score (30.7-71.8 with higher scores indicating more pain) in the weight loss arm before and after weight loss intervention.

    Time frame: 1 year

  8. Patient-reported quality of life changes with preoperative weight management program

Started Jun 2023 (actual). Primary completion is estimated for Jun 2028, 59 months after the start.

Of 31 interventional studies with no phase under Hernia, Abdominal, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 60. This study's planned 59 months is above that.

Since we started tracking on Sep 25, 2026, the dates moved once, on Nov 10, 2026: primary completion Jun 2027 → Jun 2028 and completion Jun 2027 → Jun 2028.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
