About this study
Official title: Mesh-repair With Inraperitoneal On-lay Mesh (IPOM) for Parastomal Hernia
Parastomal herniation is difficult to treat. Several different treatment has been tested but still none has revealed to be superior. The use of a mesh has been shown to be a promising way of treating. In this study the investigators will evaluate safety and hernia recurrence rate with a mesh tailored to treat parastomal hernias "Parastomal hernia mesh BARD" in patients with parastomal hernia requiring surgery.
Read the detailed description
Parastomal hernia is a common complication in patients with a stoma and may cause the patient difficulties with stomal dressing and leakage of stomal content, as well as pain and risk for incarceration. The exact hernia incidence is not known, it depends on the definition of whether a bulge is considered a hernia or not, as well as the duration of follow-up. The reported incidence ranges between 0 and 52%. The majority of parastomal hernias develop within a few years after the index operation, but can appear as late as 20 years after surgery.
There is no superior treatment for an existing parastomal hernia. Several methods have been tested and used such as stoma relocation, sutures to narrow the opening in the fascia and abdominal wall and fixation and closure of the lateral space but none has proven to prevent from recurrence of herniation. Mesh repair has been shown to give a lower recurrence rate 0-33%. No technical factor, such as site of stoma formation (through or lateral to rectus abdominis muscle), related to the construction of the stoma was proven to prevent hernia formation.
To find a way to prevent the occurrence of parastomal hernia is an important issue. Today there are reports proposing a mesh in sublay position at the index operation would prevent hernia formation. Although the results are promising these studies are small and they do not meet the issue late complications according to the mesh implant.
The use of intraperitoneal on-lay mesh (IPOM) is widely used to treat incisional hernia. A new mesh (Parastomal hernia mesh BARD) has been tailored to treat parastomal hernia. To evaluate safety and hernia recurrence rate using the BARD-mesh for treating parastomal hernia a prospective multicentre non-randomised study is performed. The aim is to include 50 patients in the study.
Patients with parastomal hernia requiring surgery due to leakage, problems with stoma dressing, bulging, incarceration and other problems related to the hernia will be offered enrollment in the study after informed consent. The preoperative examination include clinical examination, three dimensional ultrasonography (3D) and or computed tomography (CT) of the abdomen.
Surgery at the four hospitals will be performed by experienced colorectal surgeons with a special interest in parastomal hernias. Postoperatively the patients will be allowed to mobilize according to each hospital postoperative routines. Follow-up visits at one month, one year and three year are scheduled. Early complications like infections, ileus, myocardial infarction, pneumonia, urinary infection and thrombosis are evaluated at one-month follow-up by clinical examination. At one and three year follow-up late complications and possible recurrence of parastomal hernias will be searched for. CT will be performed one year postoperatively. At the three year follow-up CT and or 3D will be performed.
Important outcome measures are complications and recurrence of parastomal hernia.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing IPOM Mesh-repair parastomal hernia in people with Parastomal Hernia, run by Norrbottens Lans Landsting.
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 1 inclusion and 1 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 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Parastomal recurrence rate (time frame: One year and three year). 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 Mar 2015.
