Filter by:Eventration corresponds to the dehiscence of the abdominal wall, with passage of peritoneum and / or intra-abdominal viscera, through an acquired orifice of the abdominal wall. It is secondary to an old incision and occurs in 10 to 20% of cases after a laparotomy. At present, if there is no debate on the type of prosthesis to implant in case of clean surgery: it is a synthetic prosthesis. But in the case of contaminated surgery (modified Ventral Hernia Working Group grade 3), there is no consensus. Since the 1990s, biological prostheses have been recommended, but they represent significant expenses for health facilities. They are very numerous, and their prices vary between 3 000 € and 12 000 €. The choice is therefore difficult for the surgeon. In 2016 the Strasbourg University Hospital general surgery team made the choice to use biosynthetic prostheses. This attitude does not seem consensual and is not based on any recommendations at present, either in France or internationally. The homogenization of practices requires the availability of clinical and medico-economic data, particularly in view of the price differences that exist between different types of prostheses. The main objective of this study will be to compare the use of biosynthetic prostheses with biological prostheses in the treatment of curative surgical treatment of mVHWG grade 3 incisional hernias in terms of cost and serious complications at 6 months. The secondary objective of the study will be to estimate the number of early recurrences at 6 months avoided, thanks to the use of biosynthetic prostheses compared to biological prostheses.
The purpose of this protocol is to determine the safety and efficacy of abdominal wall transplantation as a treatment for the reconstruction of abdominal wall defects. Abdominal wall transplantation may be performed alone or in combination with another transplant.
Randomized clinical trial comparing open preperitoneal mesh, retromuscular mesh and suture repair for ventral hernias less than 3 cm diameter
This study aims to evaluate if the risk of developing ventral hernia after liver transplantation can be reduced through the prophylactic implantation of a synthetic, fully resorbable mesh "Phasix" in the course of liver transplantation. Patients will be randomized in a 1:1 ratio to receive either Phasix mesh or standard surgery without the use of Phasix. Ultra-sound examinations of the wound area will be performed 14 days, 3, 6 and 12 months after liver transplantation. Furthermore, presence of infections, seroma, pain and other problems in the wound area will be assessed.
The proposed study aims to assess the effect of different levels of muscle relaxation on the success of low-pressure insufflation, surgical conditions and patient recovery following laparoscopic repair of a ventral hernia (VHR) between 2 and 10cm in diameter. Patients will be randomized to moderate (TOF 1-2) or deep (post tetanic count 1-2) relaxation. Specific Aim 1. Compare two different modes of neuromuscular blockade (moderate and deep) on the ability to maintain low insufflation pressure during laparoscopic VHR. All procedures will start with low-pressure insufflation (8 mm Hg). Surgeon assessment of the conditions will be serially performed during surgery on an established visual scale. If conditions are deemed less than adequate (score 1-2), insufflation pressure will incrementally increase up to 15 mm Hg. Outcome for this specific aim will be the mean insufflation pressure during each procedure, and the ability to perform low-pressure laparoscopic VHR. Specific Aim 2. Evaluate the success of moderate neuromuscular blockade on the ability to maintain good conditions (visual scale grade 4 or 5) for each. Surgical conditions will be considered successful when scores are maintained at 4 or 5 throughout the duration of the procedure. Outcome for this aim will be the mean score for surgical condition assessment for each procedure, using a previously published surgeon-driven scoring system (score 4-5 will be used as a surrogate of good visualization). Specific Aim 3. Assess patient recovery with low and high insufflation pressures during laparoscopic VHR. Patient overall satisfaction with recovery, pain level, pain medication requirement, PONV incidence and severity will be assessed in multiple time points following surgery. Outcomes for this aim will be mean pain (visual scale), PONV severity (analogue score) and incidence (binary outcome), and patient satisfaction using the QoR-15 survey. Assessments will be performed at 30 minutes, 1, 12 and 24 hours following surgery.
To date, there have been no prospective randomized controlled trials that compare various biologic mesh materials in the context of abdominal wall reconstruction. As a result, this proposal describes a 'head to head' randomized controlled trial (RCT) between 2 of the market's most popular biologic meshes. Strattice (noncross-linked porcine dermis, LifeCell Inc.) will be compared to Permacol (cross-linked porcine dermis, Covidien Inc.) in a randomized manner. Although there are significant differences between these mesh products with regard to procurement, tissue processing and cost, clinical controlled trials are needed to compare their performance.
The primary objective of the present study is to investigate a possible correlation between abdominal wall function and subjective measures of QoL before and after laparoscopic repair of small- to medium sized incisional hernia. This prospective study includes 25 patients undergoing laparoscopic incisional hernia repair. Abdominal wall function is examined by determination of maximal truncal flexion and extension with a fixated pelvis using a Goodstrength dynamometer (Metitur Ltd., Jyväskylä, Finland). Subjective scores of QoL (HerQLes), pain (visual analogue scale) and physical activity (International Physical Activity Questionnaire) are assessed. Patients are examined before, one month after and three months after the operation. Furthermore, pulmonary function is examined preoperative and three months postoperative by standard spirometry (forved vital capacity, peak expiratory flow, forced expiratory volume in 1 second) as well as maximum in- and expiratory pressure is measured.
The purpose of the study is to compare the clinical outcomes of two commonly used, FDA-approved biologic meshes in hernia repair and abdominal wall reconstruction (Strattice and XenMatrix). The two meshes are derived from pig skin from which cells have been removed and which have been sterilized. The two meshes are made by two different companies using different processes.
Background: Laparoscopic repair of ventral hernias has gained popularity, since many studies and a recent meta-analysis have reported encouraging results and recurrence rates similar to open repair. The choice of the mesh and fixation methods is of paramount importance during laparoscopic approach, and nowadays, lightweight macropore meshes specifically designed for laparoscopic approach represent the first choice in several studies, due to the biomechanical properties and the optimal integration into the abdominal wall. No data with statistical relevance exist on the choice of fixation methods. Primary end point of the present Italian multicentric prospective randomized trial is to evaluate the safety and effectiveness of two different tacks to fix the lightweight polypropylene mesh (Physiomesh™) during laparoscopic incisional hernia repair: metallic spiral tacks (Protack™) vs absorbable "U" shaped tacks (Securestrap™) Design of the Study: 200 patients with ventral hernia will be randomized into two groups: Group A patients will be submitted to laparoscopic repair by Physiomesh fixed by Protack; Group B patients will be submitted to laparoscopic repair by Physiomesh fixed by Securestrap. Blind randomization will be guaranteed by an on-line software with specific key access for every surgical unit participating in the study. Patients demographics and characteristics, preoperative studies, intraoperative and postoperative results and complications, as well as scheduled follow-up will be recorded and uploaded to the database. Data represented by continuous variables will be expressed as arithmetic mean +/- standard deviation. Other data will be expressed as geometric mean +/- 95% confidence interval. Data representing low incidence events will be expressed as number and percentage of occurrence for each group. Statistical significance for all analyses will be indicated by a p value of 0.05 or less.
