TIGR vs Polypropylene (Permanent) Mesh: Randomised Trial

Hernia

Abdominal wall defects, Inflammation reactions, Amount of tissue ingrowth, Adhesion formation, Shrinkage profiles of the implant

Hypothesis: TIGR mesh as a reconstruction material is a more effective mesh for the repair of the abdominal wall post lipectomy, transverse rectus abdominis myocutaneous (TRAM) / deep inferior epigastric perforator (DIEP) flap.

In this study we will be conducting a randomized trial to study the efficacy of TIGR as a preferred reconstruction mesh for the repair of the abdominal wall post lipectomy, TRAM / DIEP flap. Aims - 1. Investigating the efficacy of TIGR as a preferred reconstruction mesh for the repair of the abdominal wall post lipectomy, TRAM / DIEP flap. Efficacy of TIGR will allow us to determine the stability of the material in the abdominal wall reconstruction. 2. Study the absorption characteristics of TIGR implant as compared with a non absorbable polypropylene mesh. Absorption characteristics can be determined by the amount of tissue ingrowth, adhesion formation and shrinkage profiles of the implant and it can be detect using ultrasound. 3. To determine whether any reactions to the implant will occur. These reaction if any will manifest as inflammation reactions which may be evident on clinical followup and can be detect by ultrasound. Patients to be recruited : 80 randomized equally into the 2 groups Age range: 21 - 80 All patients undergoing lipectomy, TRAM / DIEP flap reconstruction will be recruited into the study. Trial Duration: July 2010 - July 2015 Follow up: Postoperative 1 week, 1 month, 3 months, 6 months, and 12 months Ultrasound will be done to determine the amount of tissue ingrowth, adhesion formation and shrinkage profiles of the implant in all these follow up appointments. Complications if any can also be detected by the Ultrasound.
