Active clinical trials for "Hernia, Ventral"

The purpose of this study is to determine if mesh weight has an impact on postoperative pain, ventral hernia recurrence, incidence of deep wound infection, and overall quality of life following ventral hernia repair with mesh.

Clinical, controlled, randomized, prospective study. Ventral hernias between 2(1.5)cm and 7 cm, laparoscopic surgery with intraperitoneal onlay mesh. Three randomization groups of 25 patients giving a total of 75 patients. Mesh is fixated with either Protack, Securestrap or Glubran II. Primary outcome: postoperative pain on the 2nd postoperative day. Secondary outcomes: pain, quality of life, recurrence and adhesions at 1, 6, 12, 24, 36, 48 and 60 months postoperative.

General: antibiotic prophylaxis: cefazoline (Cefacidal™) 2 gram iv administered 30 minutes before surgery Laparoscopic surgery at least 5 cm overlap (mesh diameter should exceed hernia size by at least 10 cm) with or without anchoring transparietal sutures or double crown technique

The purpose of this research is to compare open ventral incisional hernia repair to the laparoscopic repair with respect to complications, recurrence, pain, return to normal activities of daily living, and return to work.

Ventral hernias can be repaired using a variety of techniques, with smaller defects often being amenable to minimally invasive surgical (MIS) approaches. For many years, the standard of care MIS approach to ventral hernias has been the laparoscopic intraperitoneal onlay mesh (IPOM) approach, in which a large piece of mesh is placed inside of the abdomen and fixed to the inner abdominal wall using a combination of sutures and/or mechanical tacks. For selected patients, the IPOM approach has demonstrated benefits over open repair, including decreased postoperative length of stay and decreased incidence of surgical site infection. However, concern regarding long-term outcomes of placing mesh inside the abdomen have spurred the search for alternate approaches to MIS ventral hernia repair. This includes the enhanced-view totally extraperitoneal (eTEP) approach, in which the retromuscular plane is accessed and developed so a large piece of mesh may be implanted outside of the abdominal cavity. The theoretical benefits of this approach are that patients may experience reduced pain because mechanical mesh fixation is not required (as compared to traditional IPOM approaches in which mesh is fixed to the inner abdominal wall) and that mesh is kept outside of the abdominal cavity and away from the viscera, allowing use of less expensive, uncoated mesh and theoretically reducing risk for long-term mesh related complications. While popularity of eTEP has grown, literature published regarding this approach has been mostly retrospective, consists of relatively small series of patients, and suffers from selection bias. For the one prospective study of eTEP published by Radu, et al, there was no comparator arm. The investigators will conduct a registry-based randomized controlled trial comparing MIS approaches for repair of small to medium-sized ventral hernias, specifically eTEP versus IPOM. This will occur through the Americas Hernia Society Quality Collaborative (AHSQC). Our hypotheses are multiple: 1) Patients with ventral hernias undergoing eTEP will experience a 30% decrease in pain scores by postoperative day 1 compared to patients undergoing IPOM; 2) eTEP will be associated with higher median direct costs per case versus IPOM; 3) eTEP will be associated with equivalent 1-year hernia recurrence rates versus IPOM; 4) eTEP will be associated with significantly increased intraoperative surgeon workload compared to IPOM.

Laparoscopic ventral hernia repair (VHR) is usually performed by reducing the contents in the hernia sac from the abdominal cavity and then covering the defect from the inside with a mesh, i.e. Intraperitoneal Onlay Mesh (IPOM). This means that the hernia sac is left in situ anterior to the mesh. This may, however, predispose for the development of fluid in the hernia sac, i.e. seroma. The risk of seroma development may be reduced if a the defect is closed before the mesh is applied. Closing the defect may, however, cause tension and pain from the abdominal wall. Instead of closing the defect, the part of the peritoneum constituting the hernia sac may be used for closing the defect. In this case, the peritoneum is dissected from the edges of the hernia sac and then used as a flap that is fixated to the edges of the hernia sac on the opposite side. In a previous study (BriClo), we compared defect closure as control group with peritoneal bridging. That study showed an increased risk for postoperative pain if the defect was closed. In order to evaluate whether peritoneal bridging reduces the seroma development following ventral hernia repair, we are undertaking a double-blind randomized controlled trial comparing no closure of the defect with peritoneal bridging. The goal is to randomize 100 patients undergoing laparoscopic ventral hernia repair. Clinical follow-up is performed three months, six months and one year after surgery. At all occasions, the patient is requested to fill in the Ventral Hernia Pain Questionnaire (VHPQ) and an investigation is done in order to assess the presence of seromas, recurrences or other local complications. Duration until return to work is registered. One year after surgery, computer tomography is performed in order to quantify the volume of seromas.

The primary objective of this study is to examine and compare the outcomes associated with the use of Flex HD®, a human acellular dermal matrix (HADM), and Strattice™, a porcine acellular dermal matrix, (PADM) when used as a reinforcing material in the repair of large complicated abdominal wall hernias.

The aim of this study was to perform a randomised clinical trial comparing the use of closed-suction tubular drains and progressive tension sutures in individuals with large incisional hernias subjected to onlay mesh repair to evaluate the occurrence of seroma and surgical wound infection after surgery.

Ventral hernia repair may be associated with significant postoperative pain. Pain is typically managed with intravenous (IV) and oral medications that come with their own risks, such as nausea, constipation, sedation, respiratory depression, increased bleeding, and/or kidney or liver dysfunction. The quadratus lumborum peripheral nerve block has been shown to produce anesthesia of the anterior abdominal wall in the T7 to L1 distribution. This study aims to evaluate if the addition of the quadratus lumborum peripheral nerve block (QLB) can improve pain scores, decrease the need for IV and oral pain medications, and/or speed the patients' return to normal activity.

Postoperative seroma formation is one of the most common complications after ventral hernia repair. Although some seromas may not have clinical impact, postoperative seroma formation often causes pain and discomfort and may even compromise wound healing. The use of postoperative abdominal binder is often recommended after ventral hernia repair to prevent seroma and diminish pain, but still with no scientific evidence. The primary aim of the present study is to investigate the effect of postoperative abdominal binders after laparoscopic ventral hernia repair on postoperative pain, discomfort and quality of life. Secondary, we register seroma formation. Method and material Randomized, controlled, multi-center, investigator-blinded study. A minimum of 56 patients (2X28 umbi/epi) are included, inclusion number is based on power calculations. Patients are randomized either to abdominal binder or no abdominal binder. The abdominal binder is worn from immediately after the operation and continuously for 7 days, night and day. Outcomes are based on patient self-reported registrations using Visual Analog Scales (VAS) and Carolina Comfort Scale (CCS), which is a validated, hernia-specific tool to estimate quality of life, pain and discomfort. Patients are followed-up for 30 days. For secondary outcome we use ultrasound to measure the volume of seroma formation. We use Mann-Witney, non-parametric statistics calculating the seroma formation and Friedmanns test for pain, discomfort and quality of life for the effect of time on inter- and intragroup differences during the study period. P < 0.05 is considered significant.
