Study summary

The study is a multicentre, single-blinded, randomised controlled trial. Ventral hernia patients with an aperture width between four and eight centimetres are randomised to either participation in a multimodal preoptimisation programme, including interventions to increase physical activity, promote weight loss, and optimise the treatment of comorbidities, or to surgery without structured preoptimisation. The primary endpoint is complications at three months postoperatively. During surgery, biopsies of skin, muscle, and fascia will be collected, along with pre- and postoperative blood samples, to analyse the molecular effects of preoptimisation, particularly in relation to collagen metabolism.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with a ventral hernia with a defect width of at least 4 cm.
  • Symptom burden related to the hernia sufficient to justify surgical intervention.
  • Age ≥ 18 years.

Exclusion criteria

Exclusion Criteria:

  • Expected survival of less than three years.
  • Inability to comprehend oral and written information or to provide .
  • Acute complication of the hernia requiring emergency surgical intervention.
  • General condition characterised by severe limitations in physical functional capacity.
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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Intervention

    The intervention group participates in a home-based, multimodal prehabilitation programme addressing physical inactivity, obesity, inadequate management of comorbidities, smoking, and alcohol consumption.

    Procedure: preoptimisation programme

  • No intervention
    control

    The control group will receive basic guidance on physical activity and weight management during the preoperative consultation.

Interventions

  • Procedurepreoptimisation programme

    The intervention group follows a home-based, multimodal prehabilitation programme targeting physical inactivity, obesity, comorbidities, smoking, and alcohol use. Designed to suit both rural and urban populations in northern Sweden, the programme lasts for a minimum of three months before surgery.

What researchers measure

Primary outcomes

  1. Complications at three months postoperatively

    Incidence of surgical and medical (including anaesthetic) complications at 3 months postoperatively.

    Time frame: 3 months postoperatively

Secondary outcomes

  1. Complications at twelve months postoperatively

    Incidence of surgical and medical complications at 12 months postoperatively.

    Time frame: 12 months postoperatively

  2. Patient-reported pain

    Patient-reported pain measured with Ventral Hernia Pain Questionnaire, VHPQ. Max score is 40 and minimum score is 0, a lower score indicates less abdominal wall pain.

    Time frame: Measured at inclusion, preoperatively, 3 and 12 months postoperatively.

  3. Quality of life with EQ-5D

    Quality of life assessed using the EuroQol 5-Dimensions questionnaire (EQ-5D index score). Max score is 1.0, which equals to perfect health and a lower score indicates lower quality of life with 0 is equivalent to death. Negative scores indicated health states considered worse than dead (e.g. severe disability).

    Time frame: Measured at inclusion, preoperatively, 3 and 12 months postoperatively.

  4. Aesthetic outcome

    Patient reported aestethic outcome measured with a Numerical Ratin Scale, NRS scale, range 1-10 where a higher score indicates better patient reported aesthetic outcome.

    Time frame: Measured at clinical follow-upat 3 and 12 months postoperatively.

  5. Recurrence rate

    Recurrence of ventral hernia.

    Time frame: Measured at clinical follow-up at 3 and 12 months postoperatively.

  6. Change in physical activity

    changes in physical activity measured with accelerometer for one week.

    Time frame: meassured close to inclusion and within a few weeks preoperatively.

  7. Weight

    Weight measured i kg.

    Time frame: Measured at inclusion, preoperatively, 3 and 12 months postoperatively.

  8. Collagen metabolism

    Difference between study groups in the expression levels of a panel of markers of collagen degradation and synthesis (including CHP, Collagen 1 and 4, MMP) in tissue samples taken from fascia, muscle and skin.

    Time frame: Biopsies will be taken perioperatively and thus be avalable for analysis when all study subjects have undergone surgery.

  9. Hba1c

    Hba1c in bloodsamples

    Time frame: at baseline, perioperatively, postoperative day 1, at follow up 3 and 12 months postoperatively.

  10. Hernia aperature width

    Hernia aperature width

    Time frame: measured peroperatively and on preoperative ct-scan preinclusion or within a few weeks after inclusion

  11. B-PETH

    B-PETH

    Time frame: at baseline, perioperatively and at follow up at 3 and 12 months postoperatively.

  12. Rutine labarotory tests

    Number of participants with abnormal routine laboratory tests results

    Time frame: At baseline, perioperatively, postoperative day 1, at follow up 3 and 12 months postoperatively

  13. Hyaluronan metabolism

    Difference between study groups in the expression patterns and histological distribution of hyaluronan and hyaluronan metabolism-related factors (including CD44, TRAMM, and hyaluronidases) in tissue samples taken from fascia, muscle and skin.

    Time frame: Biopsies will be taken perioperatively and thus be avalable for analysis when all study subjects have undergone surgery.
