About this study

Official title: Use of Mosquito Net Mesh in Comparison With Polypropylene Mesh for Ventral Hernia Repair.

It´s a pilot study, randomized, realized in the Central Hospital "Dr. Ignacio Morones Prieto", SLP, Mexico.

Hypothesis:

The polyethylene mesh is secure in open ventral repair.

Read the detailed description

It´s a pilot study, randomized, realized in the Central Hospital "Dr. Ignacio Morones Prieto", SLP, Mexico.

The simple size for pilot study was been calculated in 20 patients, according with Browne for not knowing the variability of the treatment. 10 patients in the group of Polypropylene mesh (Prolene ®), braided monofilament thread, macropore, weight of 108.1 g/m2, fibres diameter of 0.53 mm, tensile force of 156.6 N/cm, with a pore of 1.6 mm2, in different size of 15 x 15 cm, 20 x 20 cm and 30 x 30 cm, and 10 patients in the group of mesh of PEBD (mosquito net), braided monofilament thread, macropore, ,weight of 53.7 g/m2, fibers diameter of 0.48 mm, tensile force of 42.7 N/cm and pore of 1.8 mm2, in different size 15 x 15 cm, 20 x 20 cm and 30x 30 cm donated by Dr. Ravindranath R. Tongaonkar. The sterilization were done in ethylene oxide.

The randomisation for allocation the type of mesh for each patient was realized with numbers generated by computer with the program R version 3.0.2 with the simple function.

The statistical analysis was carried out by the programs: JMP 8 (SAS Institute Inc., Cary, NC, USA) and R 2.15.1 23.

The ventral hernia repair were carried out with standardized technique, placed the mesh int the preperitoneal or retromuscular space fixing with 2-0 poplypropylene suture and le fe active-close drainage, 30 minutes before the incision, prophylactic antibiotic 1gm of cefalotin was administered, in both groups, the patient was discharge at the first postoperatory day with drainage and retired at the first review at 1 week and recited at one, three, six and twelve months for reviewer.

The descriptive analysis of categorical variables was expressed with frequencies and percentages; the numerical ones with normal distribution in averages and standard deviation, the variables with distribution not normal with medians and status (maximum and minimal values). The values of p<0.05 were considered to be significant.

This study was evaluated and accepted by the Committee of Investigation and the Committee of Ethics, with number of record 42-17.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of Recurrence

    Rate of Reappearance of a ventral hernia post procedure after a year.

    Measured: One year

Secondary outcomes (3)

    Number of participants with open ventral hernia repair that have adverse events as infection post procedure determined by clinical, leukocytosis and positive bacterial culture.

    Measured: first week, 1 month, 3 month, 6 month and One year

  2. Seroma

    A seroma is a collection of fluid that builds up under the surface of your skin.

    Measured: first week, 1 month, 3 month, 6 month and One year

  3. length of hospital stay

    the average number of days that patients spend in hospital.

    Measured: Days

Results are not available in the source record.

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?

Rate of Recurrence (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 NCT03324854, which also lists 16 linked publications.

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 9 Nov 2017.
