Abdominal Wall Function and Quality of Life and Before and After Incisional Hernia Repair (QualiFunc)

September 2, 2015 updated by: Kristian Kiim Jensen, Bispebjerg Hospital

The primary objective of the present study is to investigate a possible correlation between abdominal wall function and subjective measures of QoL before and after laparoscopic repair of small- to medium sized incisional hernia.

This prospective study includes 25 patients undergoing laparoscopic incisional hernia repair. Abdominal wall function is examined by determination of maximal truncal flexion and extension with a fixated pelvis using a Goodstrength dynamometer (Metitur Ltd., Jyväskylä, Finland). Subjective scores of QoL (HerQLes), pain (visual analogue scale) and physical activity (International Physical Activity Questionnaire) are assessed. Patients are examined before, one month after and three months after the operation. Furthermore, pulmonary function is examined preoperative and three months postoperative by standard spirometry (forved vital capacity, peak expiratory flow, forced expiratory volume in 1 second) as well as maximum in- and expiratory pressure is measured.

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

25 years to 75 years (Adult, Older Adult)

Description

Inclusion Criteria:

  • Elective laparoscopic repair for one or more incisional hernias in the midline (at least 5 cm caudal to the xiphoid process and at least 5 cm cranial to the pubic bone), using a synthetic mesh
  • Horizontal fascial defect between 3 and 8 cm
  • Age between 25 and 75 years
  • American Association of Anesthesiologist score between I and III
  • Body mass index < 33 kg/m^2

Exclusion Criteria:

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.
Patients with incisional hernia
Patients with one or more incisional hernias, combined horizontal fascial defect 3-8 cm, planned for laparoscopic mesh repair. Patients are examined before and one and three months postoperative in regard to abdominal wall function, pain, discomfort, hernia-related quality of life and physical activity level.
Other: Examination of abdominal wall strength changes over time

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
Abdominal wall strength
Time Frame: Change at three months from baseline examination
Abdominal wall strength measured by Goodstrength Dynamometer before, one and three months after laparoscopic incisional hernia repair.
Change at three months from baseline examination
Hernia-related quality of life
Time Frame: Change at three months from baseline examination
Hernia-related quality of life (HerQLes) before, one and three months after laparoscopic incisional hernia repair.
Change at three months from baseline examination

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.
