The Transrectus Sheath Pre-peritoneal (TREPP) Technique for Strangulated Inguinal Hernia: a Case-series

March 25, 2020 updated by: Thomas Zwols, University Medical Center Groningen
n the Sint Jansdal Hospital in Harderwijk, the Netherlands, the TREPP technique is the standard operating procedure for patients with inguinal hernia. Starting from 2006, this procedure has also been used on patients that presented with an acute strangulated inguinal hernia in the emergency department, instead of the more common Lichtenstein technique. The goal of this retrospective case series is to assess the feasibility of the TREPP technique in case of an acute strangulated inguinal hernia. Patient records from 2006 until 2016 will be used to search for patients treated for acute inguinal hernia in that period. After applying the in- and exclusion criteria, patients who are eligible for inclusion will be contacted by telephone. They will be asked if they are willing to visit the surgical outpatient department once and fill out two questionnaires. The data of these questionnaires will be analyzed and published.

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.

Participation Criteria

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.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

From all acute inguinal hernia repairs patient records will searched for e-TREPP procedures. All patients will be asked to visit the outpatient department.

Description

Inclusion Criteria:

  • Emergency surgery for suspected strangulated inguinal hernia (within 6 hours after admission)
  • e-TREPP performed

Exclusion Criteria:

  • No emergency surgery (for instance, surgery day after admission or later).
  • No e-TREPP performed

Study Plan

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
e-TREPP
Patients with strangulated inguinal hernia treated with e-TREPP
Procedure: emergency transrectus sheath pre-peritoneal mesh repair (e-TREPP)
The Trans REctussheath PrePeritoneal mesh repair (TREPP) was developed in 2006 as an open preperitoneal technique to reduce CPIP. In short: a 4-5 centimeters (cm) transverse incision is made about 1 cm above the localization of the deep inguinal ring. The anterior rectus sheath is opened. After retracting the rectus muscle medially, the preperitoneal space (PPS) is bluntly dissected and a complete overview can be achieved. All possible hernia orifices can be visualized such as: a direct, indirect, pantaloon, and/or femoral hernia. A self-expandable mesh is then positioned in the PPS. Due to the "upstream principle" no mesh fixation is necessary.

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
Measure Description
Time Frame
Chronic postoperative inguinal pain according to Visual Analog Scale
Time Frame: From surgery date up to 12 years postoperatively
Patients will be asked to fill out the VAS on a horizontal line of 10 millimeters long. Patients will be asked to mark the point that indicated the amount of pain they experience. The distance from the left marker will be measured, with increasing distance at greater pain intensity.
From surgery date up to 12 years postoperatively
Recurrence rate
Time Frame: From surgery date up to 12 years postoperatively
Patient electronic records will be searched for re-operations for recurrent inguinal hernia. Also, patients will be asked in the outpatient department if they received recurrence surgery or suffer new complaints.
From surgery date up to 12 years postoperatively

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.
Outcome Measure
Measure Description
Time Frame
Short-term complications
Time Frame: Complications occuring from the start of the operation up to 30 days postoperative
Short term complications included: hematoma, wound infection, re-admission rate, medical complications and death. These complications will be retrospectively analyzed via the electronic patient files. They will be verified at the outpatient department.
Complications occuring from the start of the operation up to 30 days postoperative
Sexual complaints related to e-TREPP
Time Frame: Between >30 days postoperatively and through study completion, average 6 years
All patients will be asked if they experienced any sexual problems related to the e-TREPP surgery.
Between >30 days postoperatively and through study completion, average 6 years
