Filter by:The risk for recurrence after ventral hernia repair is often based on reoperation rates with short follow-up rather than recurrences identified by clinical examinations. The purpose of current study is find the real incidence of recurrences 3 years after ventral hernia repair and to compare with the reoperation rate.
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.
To compare the use of absorbable tackers versus permanent tack fixation using a polyester large pore mesh in laparoscopic midline ventral hernia repair in a multicenter (Belgian) prospective randomized single-blinded trial. All patients referred for elective midline ventral hernia repair should be assessed for eligibility and entered in a study log, detailing all included patients during the study period.
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.
Immediate post-operative abdominal compartment syndrome is a feared complication after hernia repair in patients with a "loss of abdominal domain." Replacement of the viscera within an unyielding stiff abdominal wall may compromise the perfusion of the intestines, elevate the diaphragm, and interfere with ventilation. The components separation technique, used to repair these massive hernias, employs bilateral relaxing incisions in the external oblique muscle and fascia in order to approximate the rectus abdominis muscles in the midline. Reducing a large volume hernia into the abdominal cavity and primary closure of the abdominal wall should cause problems both with abdominal compartment pressure and with postoperative ventilation, but in the investigators' 13-year experience with over 250 cases, this has not been seen clinically, and the investigators sought to understand why. The investigators' hypothesis is that releasing the rectus muscles from the external obliques expands the intra-abdominal compartment, reclaims lost domain, and thus reduces abdominal pressure and respiratory problems. The investigators have previously reported increased abdominal volumes using the components separation technique in a retrospective series, but patients were not standardized for the collection of data, and no pulmonary function tests were obtained in that series (Hadad, in press). The purpose of this study was to prospectively analyze the effect of this surgical technique on abdominal volume and pulmonary function.
This study will collect data on patients undergoing hernia repair using the Bard Ventrio Hernia Patch. The study will evaluate hernia recurrence rates, operating time, quality of life and complications associated with the device and surgical procedure.
The purpose of this study is to determine whether mesh fixation in laparoscopic umbilical hernia repair with fibrin glue is superior to tacks in terms of postoperative pain and recovery.
Hernia of the abdominal wall occur frequently after various surgical procedures of the abdomen and are increasingly performed by laparoscopic means. Different mesh fixation techniques are applied, but the influence of mesh fixation on shrinkage is not known in human patients. Therefore, mesh shrinkage was assessed using two different techniques for fixation.
1. General: antibiotic prophylaxis: cefazoline (Cefacidal™) 2 gram iv administered 30 minutes before surgery 2. 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
Method of fixation of the mesh in laparoscopic incisional / ventral hernia repair might influence the degree of postoperative pain. The study hypothesis is that there is no difference in postoperative pain between different methods to fix the mesh in laparoscopic incisional / ventral hernia repair.
