Abdominal Rectus Diastasis (ARD) Reconstruction (ARD)

October 18, 2024 updated by: Anders Thorell, Karolinska Institutet

Minimally Invasive Abdominal Wall Reconstruction in Symptomatic Rectus Diastasis

The aim of this study is to investigate whether abdominal wall reconstruction through laparoscopic surgery can be recommended as a safe treatment alternative for patients with symptomatic rectus diastasis, and if this type of treatment leads to improved quality of life, trunk stability and reduced pain.

Study Overview

Status

Status

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

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

Investigate whether surgical reconstruction with laparoscopic technique can lead to improved quality of Life, trunk stability and reduced pain in patients with symptomatic rectus diastasis. The study will also compare two different laparoscopic surgery methods for abdominal wall reconstruction: narrowing of linea alba with continuous suture with or without mesh.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

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
Rate of recurrence
Time Frame: 1 year
computed tomography
1 year

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
Visual Analog Pain Scale (VAS)
Time Frame: 1 year, 3 years
Scale from 0 to 10, where 0 is no pain and 10 is the worst possible pain
1 year, 3 years
Abdominal stability
Time Frame: 1 year, 3 years
patient self-esteem by one question; do you feel that the instability of the abdominal wall has disappeared, yes/no/partially
1 year, 3 years
SF-36 Quality of Life instrument
Time Frame: 1 year, 3 years
The RAND-36 It is comprised of 36 items that assess eight health concepts: physical functioning, role limitations caused by physical health problems, role limitations caused by emotional problems, social functioning, emotional well-being, energy/fatigue, pain, and general health perceptions. Physical and mental health summary scores are also derived from the eight RAND-36 scales. Higher scores mean a better outcome.
1 year, 3 years
VHPQ is a questionnaire for the assessment of pre- and postoperative pain
Time Frame: 1 year, 3 years
The questionnaire comprises 20 questions The first six questions concern the level and duration of pain. The next seven questionsrelate to the impact on daily activities. The final questions deal with patient satisfaction and how physically demanding the patients regard their occupation. Pain intensity in the VHPQ is assessed using a 7-step fixed-point rating scale with steps linked to pain behavior rather than numbers or verbal descriptors of pain. Higher scores mean a worse outcome.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
