Filter by:Incisional hernia is the most frequently seen long term complication in surgery causing much morbidity and even mortality in patients. Despite studies on the optimal closing technique for laparotomies, the risk for incisional hernia after midline incision remains about 5-20%. It has been established that implementing a mesh reduces recurrence of the incisional hernia but still the results of repair are often disappointing. Incisional hernias can become increasingly complex due to complicated abdominal wall defects caused by a disturbed anatomy, fistulas, burst abdomen, wound and mesh infections. In these cases it is not save to repair the incisional hernia by means of a synthetic mesh and other augmentation tools need to be implemented. In the recent years the use of biological meshes has been gaining popularity. Recent reports of the use of collagen-based prosthesis have suggested that they support new vessel growth, do not excite a significant foreign body reaction, form fewer adhesions, are well incorporated into host tissues with minimal wound contraction, and can be used in grossly contaminated wounds with fewer infective complications. Biologic meshes are harvested from a source tissue and processed for medical use but they vary widely in their processing methods. They include tissues of human or animal origins, both chemically cross-linked and non cross-linked processes, and submucosal, pericardial, or dermal tissue sources. Current studies investigating the effectiveness of these meshes are small and have short periods of follow-up. These shortcomings can be explained to high cost of the meshes and unclear indication when to use a biological mesh. The aim of this study is to investigate the short and long term effects of the Strattice biological mesh. The investigators will also inquire why a biologic mesh was used and what the direct and indirect costs were.

The aim of this study is investigate the short and long term effects of the Permacol© biological mesh. Also the investigators will be inquiring why a biologic mesh was used, what is the true indication to use a biological mesh.
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.
"Nanotechnologies applied to General Surgery and Emergency Surgery: The Buckypaper as a new fixing method for prosthetic materials in the treatment of abdominal wall hernias, diaphragmatic hernias, diaphragmatic rupture, incisional hernia and abdominal wall disaster in laparotomy procedure and laparoscopic procedures". Experimentation on breed pig Lantrace ANIMAL MODEL.
The posincisional hernia is considered a delicate complication , with an incidence of 10-12% in patients undergoing laparotomy may reach 45% in case of emergency and high-risk patients . It is estimated that in the United States are made about a million of reoperations for correction of this complication , with millions and despite the myriad studies that have been done in recent years there has been a decrease in the incidence losses and mortality of this complication. Given the seriousness of this problem the last global consensus guidelines sent to the surgical community in three main areas: Identify the importance of the problem, improve the theoretical knowledge and technical capacity in the closure of the abdominal wall and Implement prophylaxis in selected patients. The technique of reinforced tension line (RTL) was proposed by hollinsky and collaborators and is a strengthening of the abdominal incision with placement of a suture that runs lateral to the edge of the incision and closure of the abdominal wall is performed the usual manner with the only surgete continuous suture for closure is placed lateral to the suture reinforcement. In the present study may contribute to these guidelines and to groups of patients at high risk were identified and applying the RTL technique and demonstrate that its use is safe and useful in reducing the presence of this complication could be implemented as prophylaxis handling the same . The RTL method was applied experimentally on bodies to close the abdominal wall also be used in a cohort of patients for hernia repair wall , showing that by using it the abdominal wall is more resistant to shear forces by theoretical foundation that exists to show that could prevent the development of incisional hernias. There are no studies in the literature comparing this technique against conventional methods of closure of the abdominal wall as to the prevention of the same.
The purpose of this study is to evaluate the efficacy of the Cook Biodesign mesh for the repair of complex ventral incisional hernias. Using materials to reinforce tissue defects is indicated as standard of care for this type of surgery. The Cook Biodesign mesh is currently FDA-approved for implantation to reinforce soft tissues where weakness exists, but the investigators would like to collect additional follow-up information to continue to assess the durability of the repair after placement of the hernia mesh. This follow-up would include the collection of information about complications such as infections and seromas (collections of fluid around the surgery site), as well as hernia recurrence and quality of life questionnaires. Patients who qualify to take part in this study have been diagnosed with a ventral incisional hernia and will have been scheduled for a surgical hernia repair. This surgery will be an "open" surgical procedure and reinforcing your tissue with material is indicated for this type of hernia repair.
The purpose of this study is to learn how well Liposomal Bupivacaine (Exparel™) controls post-operative pain in patients undergoing both open and laparoscopic (minimally invasive) abdominal hernia repair surgery.
Retrospective analysis of patients undergoing laparoscopic incisional hernia repair. Study group: Patients with incisional hernia post liver transplantation Control group: Patients with incisional hernia post any other laparotomy in the upper quadrant. Primary study outcome parameter: Risk of hernia recurrence. Secondary study outcome parameters: - Hernia repair-related infection rate - Postoperative morbidity Statistical analysis: Comparison of study versus control group, univariate and multivariate analysis, Chi² and Mann-Whitney-U tests. P-values <0.05 were considered significant.
In France around 5,000 colostomies are performed after elective or emergency surgery. These colostomies could be associated with major outcomes including parastomal hernia (4 - 53%) of cases. To reduce the incidence of these outcomes, several methods have been proposed but the more pertinent consist in the use of a biological mesh during the stoma's conception. Nevertheless there is no data on the use of a biological mesh (StratticeTM) for the prevention of parastomal hernia.
Despite of technological advances in surgery, incisional hernia and bowel obstruction remain frequent surgical complications. To date, the relationship between these two types of surgery and the occurrence of incisional hernia remains unclear. This is an observational study to evaluate outcomes of incisional hernia with respect to the incision site and adhesion-related bowel obstruction after open and laparoscopic colorectal surgery.
