Study summary

The use of mesh in the repair of umbilical hernias is a gold standard. The best location of the mesh remains a matter of discussion, i.e. it might be placed inside the peritoneal cavity (open intraperitoneal onlay mesh) or between the peritoneum and the muscle layers, so not in contact with the viscera (retromuscular or preperitoneal). The Rebound mesh consists of polypropylene, i.e. the most used fabric for meshes, in combination with a nitinol memory ring. This ring allows the surgeon to position the mesh more flat, with less wrinkling and subsequently better tissue ingrowth. It also saves time for both patient's anesthesia and the surgery.

This type of mesh (one coated with PTFE for intra-abdominal use and one pure polypropylene for preperitoneal use), will be used in this multicentric trial, to evaluate the best procedure in terms of efficacy, safety and postoperative complications.

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

  • written from the patient or his/her legal representative
  • primary umbilical hernia requiring elective surgical repair
  • diameter between 0 and 3 cm

Exclusion criteria

Exclusion Criteria:

  • no written
  • incisional hernia at the level of the umbilicus
  • recurrent umbilical hernia, as they have to be considered an incisional hernia
  • emergency surgery (incarcerated hernia)
  • pregnancy
  • non-compliance
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.

What researchers measure

Primary outcomes

  1. Operation time between preperitoneal mesh placement versus intraperitoneal mesh placement.

    Time registration of the operating time will be extracted from the hospital electronic patient files.

    Time frame: Total duration of the operation with an expected average of approximately 45 minutes.

Secondary outcomes

  1. Surgical wound morbidity complication rate.

    Time frame: Up to 1 year.

  2. Recurrence Rate

    Clinical examination will be performed. No ultrasound, unless doubt about recurrence.

    Time frame: up to 2 years

  3. Pain evaluation

    A questionnaire and Visual Analog Scale (VAS) will be filled out. The patient is asked whether he or she has pain. Answer NO: VAS = 0, Yes: patient will determine the exact VAS score.

    Time frame: within 2 weeks prior to surgery, after 4 weeks, after 1 year and after 2 years

  4. Discomfort evaluation.

    A questionnaire and Visual Analog Scale (VAS) will be filled out. The patient is asked whether he or she has discomfort. Answer NO: VAS = 0, Yes: patient will determine the exact VAS score.

    Time frame: Within 2 weeks prior to surgery, after 4 weeks, after 1 year and after 2 years.
