Efficacy of an Onlay Mesh for Prevention of Incisional Hernia After Loop Ileostomy Closure

2016-09-12 18:38:21 | BioPortfolio

Summary

The aim of the present study is to determine the efficacy of the placement of an onlay mesh to prevent incisional hernia after loop ileostomy closure in patients with a prior rectal resection for cancer

Description

The primary aim of the study is to determine the efficacy of the placement of an onlay mesh for prevention of incisional hernia after loop ileostomy closure in patients with a prior rectal resection for cancer. The efficacy will be evaluated by physical examination 3, 6 and 12 months after surgery and by abdominal CT scan one year after stoma closure.

Secondary aims are to evaluate the tolerability and safety of the prothesis; complications, quality of life and the need for further treatments will be compared between the groups.

This is a multicentric study that will include patients operated on in hospitals in Catalunya for loop ileostomy closure after a prior rectal resection for rectal cancer. Elective surgery for loop ileostomy closure with ASA<4. Exclusion criteria include patients with allergy or intolerance to polypropilene, with a prior mesh on the abdominal wall, ASA ≥IV, patients with a life expectancy of <12 months, chronic renal failure in haemodialysis and patients on steroid therapy.

Patients that agree to participate in the study will be randomized using an electronic formula (Excel) of a uniformly distributed variable assigning case/control randomly until the total number of patients are included.

In the control group, after the digestive tract is reconstructed, the closure of the abdominal wall will be performed with a continuous suture of PDS loop 1/0 following Jenkins 4:1 rule and the skin will be closed using a subcutaneous purse-string closure. Patients in the study group will have the same procedure performed, and after the aponeurosis closure with PDS loop, an onlay light polypropilene mesh will be placed.

Each participant will have an assigned code depending on the participating Centre that will maintain anonymity at all times. All of the information will be registered in a database specifically designed for the study.

Statistical analysis will be performed by a descriptive study of the demographic variables and the incidence of incisional hernia after loop ileostomy closure. A comparative study between the groups will be performed using X2 test for categorical variables and t Student test or U-Mann for continuous variables. A binary logistic regression will also be performed to analyse the influence of each variable and to predict if the interventions produce incisional hernia.

Medical and Biotech [MESH] Definitions

Clinical trials that involve at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.

Work consisting of a clinical trial that involves at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.

Any woven or knit material of open texture used in surgery for the repair, reconstruction, or substitution of tissue. The mesh is usually a synthetic fabric made of various polymers. It is occasionally made of metal.

Study subjects in COHORT STUDIES whose outcomes are unknown e.g., because they could not or did not wish to attend follow-up visits.(from Dictionary of Epidemiology, 5th ed.)

Work consisting of a clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.
