Active clinical trials for "Hernia, Ventral"

The proposed study will compare the benefits, harms, and comparative effectiveness of intraperitoneal barrier-coated and non-barrier coated ventral hernia repair (VHR) mesh in reducing adhesions, adhesion-related complications, and adhesiolysis sequelae in actual patient subpopulations and clinical circumstances. A subset of the data will be analyzed to compare the benefits, harms, and comparative effectiveness of the laparoscopic and open approaches to adhesiolysis. A comprehensive array of health-related risk factors and patient-centered outcomes will be assessed in the investigators diverse patient population for proper multivariate data analysis. Specific Aim I: To evaluate and compare the adhesion characteristics of intraperitoneal barrier-coated versus non-barrier-coated mesh during abdominal re-exploration after prior ventral hernia repair. Specific Aim II: To evaluate and compare the adhesion-related complications and adhesiolysis-related complications of intraperitoneal barrier-coated versus non-barrier-coated mesh during abdominal re-exploration after prior ventral hernia repair. Specific Aim III: To determine the comparative effectiveness of intraperitoneal barrier-coated versus non-barrier-coated ventral hernia repair mesh in reducing adhesions, adhesion-related complications, and adhesiolysis sequelae in actual patient subpopulations and clinical circumstances. Specific Aim IV: To evaluate and compare the adhesiolysis-related complications of the laparoscopic and open approaches to adhesiolysis during abdominal re-exploration after prior ventral hernia repair. Specific Aim V: To determine the comparative effectiveness of the laparoscopic and open approaches to adhesiolysis during abdominal re-exploration after prior ventral hernia repair.

This is a multi-center, observational study of incisional/ventral hernia repair with NG-TSM laparoscopically. The study is not randomized and has a single treatment design assessing NG-TSM intra-operatively, its ease of use and handling characteristics.

The incidence of ventral hernias has remained inappropriately high. Any innovation in order to reduce this incidence would be simply cost-effective. Although there is still some concern about the use of mesh in clean-contaminated or contaminated surgery, based in our experimental studies, we plan to use a mesh in the primary closure of abdominal incision to prevent incisional hernias. The investigators propose a clinical trial to assess a model to prevent the incisional hernia after laparotomy to treat colorectal carcinoma is scheduled. A simple randomization is scheduled: in the intervention group a prefascial large-pore low-weight 5 cm wide polypropylene mesh is fixed covering the midline closure; in the control group a conventional closure with a running suture of long-term absorbable material with a suture/wound length ratio 4:1. The sample size was calculated with an estimated incidence of ventral hernia of 25% in the control group and 10% in the intervention group, 0,05 alfa and a 0,15 beta error. The main goal is the appearance of a ventral hernia after 24 months of follow-up. Other outcomes are wound complications and morbidity. Exclusion criteria are adult patients with a previous ventral hernia, estimated survival of less than 6 months or hemodynamic instability during surgery. The diagnosis of ventral hernia will be assessed by clinical exploration on 3,6,12,18 and 24 months and abdominal CT controls at 6,12, and 24 months. The study will be statistically evaluated with SPSS 18.0.

The purpose of this study is to investigate what happens to biologic mesh in the body over time on a molecular level. To date, it is not known what agents, enzymes, or proteins are interacting at the implantation site that contributes to mesh remodeling and/or degradation. Investigators on this project will identify patients with previously placed mesh who are needing reoperation on the same site and take a biopsy of the mesh during the normal course of surgery. Basic data surrounding the surgical procedure will be collected. The mesh samples will be analyzed for enzymes and proteins and examined histologically for processes that signify remodeling and/or degradation. Control patients will undergo biopsy of abdominal fascia at laparoscopic trocar sites in a manner that will not affect the outcome(s) of their procedure or other risk to the incision site.

This study evaluates the abdominal closure technique in emergency surgery. Half of participants will be perform the classic Large Stitch technique, while the other half will undergo the Small Stitch technique.

Observational, Retrospective, Multi-center Clinical Study on the Safety of SAFIL® MESH in Patients Undergoing Reinforcement of Soft Tissues After Abdominal Wall Surgery or Other Fascial Defects

Several questions exist when looking at ventral hernias: what is the baseline quality of life and abdominal wall function among patients with or without a ventral hernia? what is the clinical significance of a ventral hernia seen on radiography but not on clinical examination (e.g. occult hernia)? what is the natural history of quality of life of patients with and without a ventral hernia? what is the impact of disclosure of presence or absence of a ventral hernia on quality of life? Answering these questions can provide valuable information on the impact of surgery with or without subsequent ventral hernia on a patient's abdominal wall function and quality of life.

Comparison of ventral hernia repair using standard wound care versus Prevena.

The main study objective is to determine the frequency of hernia recurrence following use of Veritas Collagen Matrix.

This will be an observational study designed to collect early, short- and long-term clinical outcomes of the XenMatrix™ Surgical Graft for complex ventral hernia repair. Subjects will be expected to attend follow up visits at 1, 6, 12, 18 and 24 months following surgery.
