About this study

Official title: Prospective, Randomized Study on the Use of a Intraperitoneal Onlay Mesh for Prevention of Parastomal Hernia of Permanent Colostomy

Study is a prospective, multicenter, randomized trial evaluating whether prophylactic laparoscopic placement of a dual-component IPOM mesh around a colostomy may prevent parastomal hernia compared with conventional colostomy after abdominoperineal resection. Eligible subjects will be recruited prospectively from five Finnish Hospitals (Oulu University Hospital,Vaasa Central Hospital, Helsinki University Hospital, Lahti Central Hospital, Jyväskylä Central Hospital). Patients were considered eligible for this study if undergoing laparoscopic abdominoperineal resection for rectal adenocarcinoma. Patients are randomized to prophylactic preperitoneal placement of a dual-component mesh (Dynamesh IPOM) around permanent colostomy or to conventional permanent colostomy. Estimating a parastomal hernia rate of 50%, a sample size of 26 patients per each study group is projected to provide 90% power (1-beta) with a alpha 0.05 (2-beta) to detect a 40% reduction in risk for parastomal hernia at 1-year. Since we expect a dropout rate of 20%, 37 patients per study group will be included in this study.

All abdominoperineal resections are performed using laparosopic technique. At the and of the abdominal laparoscopic phase the straight permanent end colostomy is performed. In the intervention group the 10 x 10 cm Dynamesh IPOM mesh is cut in the middle according to volume of the bowel. Stapled bowel end is then pulled through the crosswise opened mesh, which is pushed to the abdomen and fixed to the peritoneum.

Follow-up visits are scheduled at 1-, 3- and 12-month after surgery. Patients are evaluated for their clinical status and C-reactive protein, leukocytes and hemoglobin are assessed at each control visit. Computed tomography (CT) scan with and without Valsalva maneuver is performed 12 months after surgery for radiological evaluation of possible parastomal hernia.

The primary end-point of this study is the incidence of clinically and radiologically detected parastomal hernias, and their extent 12 months after surgery. The secondary outcome end-points were colostomy-related morbidity such as stomal stenosis, necrosis and/or wound infection.The extent of parastomal hernia was graded at CT according to the Hernia Society criteria.

Statistical analysis is performed using a SPSS statistical software. Continuous variables are reported as the mean and standard deviation, whereas nominal variables are reported as counts and proportions. Univariate analysis is performed with the Mann-Whitney U test and Fisher's exact test. P-values < 0.05 are considered statistically significant.

Questions about this trial

What is this clinical trial studying?

A study testing Application of IPOM mesh in people with Parastomal Hernia, run by Oulu University Hospital.

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 4 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 23 Feb 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.

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?

Number of parastomal hernia (time frame: One year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02368873, which also lists 1 linked publication.

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 23 Feb 2015.
