PHS, Lichtenstein Mesh, and PerFixPlug for Primary Inguinal Hernia Repair - 3 Years Results
A Phase 4 study testing Lichtenstein mesh, PerFix Plug® and Prolene® Hernia System in people with Hernia, Inguinal, run by Göteborg University at 1 site in Sweden.
Trial summary
Three different techniques for the surgical repair of groin hernias are compared. Focus has been set on operation times, time to full return of functional abilities like walking in stairs etc, and if any technique has more complications than the others. Three years results are presented in the study. Read more about this study

About this study
Official title: Prolene Hernia System, Lichtenstein Mesh, and Plug-and-Patch for Primary Inguinal Hernia Repair - Three Year Outcome of a Prospective Randomised Controlled Trial
Three different techniques for the surgical repair of groin hernias are compared. Focus has been set on operation times, time to full return of functional abilities like walking in stairs etc, and if any technique has more complications than the others. Three years results are presented in the study.
Read the detailed description
Dissection requirements differ between various methods for inguinal hernia repair, which may effect operation times, pain response and possibly recovery time. The objectives of this study were to establish if any differences concerning these aspects could be detected after three principally different techniques for primary inguinal hernia repair.
472 men between 30 and 75 years with primary inguinal hernias were included in a prospective controlled study and randomised to Lichtenstein mesh (L), PerFix Plug® (P) or the Prolene® Hernia System (PHS) procedure. All patients were seen and data were collected after 2 weeks, 3 months, 1 year, and 3 years.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Lichtenstein mesh, PerFix Plug® and Prolene® Hernia System in people with Hernia, Inguinal, run by Göteborg University at 1 site in Sweden.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Dec 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time until full functional recovery (time frame: 2 weeks, 3 months, 1 year, 3 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Dec 2007; AzTrials last refreshed its copy on 6 Nov 2026.
