PHS, Lichtenstein Mesh, and PerFixPlug for Primary Inguinal Hernia Repair - 3 Years Results (BOOP)

December 21, 2007 updated by: Göteborg University

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Time until full functional recovery
Time Frame: 2 weeks, 3 months, 1 year, 3 years
2 weeks, 3 months, 1 year, 3 years
Operation time

Registered after completion of surgery
Pain after operation measured on a VAS-scale and amount of consumed analgesics
Time Frame: Day 1-14, 3 months, 1 year, 3 years after surgery
Day 1-14, 3 months, 1 year, 3 years after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
