: Ventral hernia repair remains a major clinical need. Herein, we formulated a type I collagen/elastin crosslinked blend (CollE) for the fabrication of biomimetic meshes for ventral hernia repair. To evaluate the effect of architecture on the performance of the implants, CollE was formulated both as flat sheets (CollE Sheets) and porous scaffolds (CollE Scaffolds). The morphology, hydrophylicity and in vitro degradation were assessed by SEM, water contact angle and differential scanning calorimetry, respectively...

PURPOSE: To investigate whether there is a difference between Marlex(r) and Dynamesh PP-light Marlex(r) meshes, in the abdominal wall defect correction, on rats in contaminated surgical site. METHODS: Twenty-eight Wistar rats were divided into two groups of 14, and four subgroups of seven animals. All subgroups underwent similar surgical procedure. One group received the mesh Marlex(r) and the other Dynamesh PP-light(r) for correction of the defect. Before implanting, the meshes went through a contamination process, on which was used standard solution containing 10 UFC of Escherichia coli...

INTRODUCTION: Intraperitoneal onlay mesh repair is a current technique for laparoscopic repair of ventral and incisional hernias. However, the placement of synthetic mesh intraperitoneally may potentially lead to mesh-induced complications such as adhesive intestinal obstruction, enterocutaneous fistula, or even mesh erosion into organs. Inspired by the concept of laparoscopic inguinal hernia repair, we developed a novel technique: preperitoneal onlay mesh repair (PPOM). This involves placing the mesh in the preperitoneal plane to help eliminate mesh-induced complications...

INTRODUCTION: The "MILOS concept" (mini/less open sublay repair) was developed to realize the benefits of minimally invasive surgery and avoid the disadvantages of traditional open techniques in repair of primary and secondary abdominal wall hernias. Utilizing the MILOS concept, the mesh can be placed in the retromuscular position without opening of the abdominal cavity or without the necessity to perform a large skin incision. The dissection of the retromuscular plane may be done by an open technique (MILOS) or endoscopically (EMILOS)...

BACKGROUND: In ventral hernia repair, when prosthetic material is placed intraperitoneally, it may lead to an inflammatory reaction resulting in adhesions between the mesh and abdominal viscera. Several meshes have been developed to minimize this process. In this experimental study, the ability of different combined meshes to attenuate the adhesion formation was examined. METHODS: Three commercially available lightweight porous combined meshes were placed intraperitoneally to repair an abdominal wall defect in rats: DynaMesh-IPOM (PVDF + PP), TiMesh (titanium-coated filament PP) and C-QUR/FX (omega-3 fatty acid-coated filament PP)...

INTRODUCTION: Minimally invasive laparoscopic and robotic techniques for ventral hernia repair have evolved to achieve the benefits and minimize the limitations of both the open Rives-Stoppa sublay mesh repair and laparoscopic intraperitoneal onlay mesh (IPOM) repair. By combining the principles of a retromuscular repair with the benefits of a minimally invasive approach, these techniques attempt to decrease recurrence, increase functionality, exclude mesh from the viscera, limit infection and wound complications, and minimize pain...

INTRODUCTION: Spigelian hernia (SH) is a rare ventral hernia occurring near the lateral border of the rectus muscle. The treatment remains controversial and depends on institutional expertise. Although laparoscopic surgery is a good adaptation for the repair of ventral hernias, only a few cases have been reported in the literature. Here, we report a case of totally extra-peritoneal (TEP) repair for bilateral SHs. PRESENTATION OF CASE: A 74-year-old Japanese man presented with asymptomatic bulges in the right lower abdominal quadrant...

INTRODUCTION: Mesh migration into the intestine is very rare after incisional hernia repair. CASE REPORT: We report the case of transmural mesh migration from the abdominal wall into the small bowel presenting as recurrent small bowel obstruction 18 years after repeated surgical repair of an incisional ventral hernia. At surgery, a mesh was found inside the resected ileal loop. DISCUSSION: Mesh migration into the intestine is a possible, although very rare, complication after incisional hernia repair with nonabsorbable meshes...

BACKGROUND: The study investigates the relationship between motor coordination errors and total errors using a human factors framework. We hypothesize motor coordination errors will correlate with total errors and provide validity evidence for error tolerance as a performance metric. METHODS: Residents' laparoscopic skills were evaluated during a simulated laparoscopic ventral hernia repair for motor coordination errors when grasping for intra-abdominal mesh or suture...

Rectal prolapse is associated with debilitating symptoms and leads to both functional impairment and anatomic distortion. Symptoms include rectal bulge, mucous drainage, bleeding, incontinence, constipation, tenesmus, as well as discomfort, pressure, and pain. The only cure is surgical. The optimal surgical repair is not yet defined though laparoscopic rectopexy with mesh is emerging as a more durable approach. The chosen approach should be individually tailored, taking into account factors such as presence of pelvic floor defects and coexistence of vaginal prolapse, severe constipation, surgical fitness, and whether the patient has had a previous prolapse procedure...

BACKGROUND: A rarely used technique for enabling closure of large ventral hernias with loss of domain is preoperative progressive pneumoperitoneum (PPP), which uses intermittent insufflation to gradually stretch the contracted abdominal wall muscles, increasing the capacity of the abdominal cavity. This allows the re-introduction of herniated viscera into the abdominal cavity and assists in closure of giant hernias which may otherwise be considered inoperable. METHODS: This was a prospective study assessing 16 patients between 2013 and 2015 with multi-recurrent ventral hernia...

BACKGROUND: Sandwich ventral hernia repair (SVHR) may reduce ventral hernia recurrence rates, although with an increased risk of surgical site occurrences (SSOs) and surgical site infections (SSIs). Previously, we found that a modified negative pressure wound therapy (hybrid vacuum-assisted closure [HVAC]) system reduced SSOs and SSIs after ventral hernia repair. We aimed to describe our outcomes after SVHR paired with HVAC closure. METHODS: We conducted a 4-y retrospective review of all complex SVHRs (biologic mesh underlay and synthetic mesh overlay) with HVAC closure performed at our institution by a single surgeon...

BACKGROUND: Our objective was to determine outcomes for complex ventral hernia repairs in a large cohort of patients utilizing an operative construct employing retrorectus placement of a narrow, macroporous polypropylene mesh with up to 45 suture fixation points for force distribution. No consensus exists on the optimal technique for repair of complex ventral hernias. Current trends emphasize large meshes with wide overlaps and minimal suture fixation, though reported complications and recurrence remain problematic...

BACKGROUND: Doxycycline, a nonspecific metalloproteinase (MMP) inhibitor, has been demonstrated to impact the strength of the polypropylene (PP) mesh-repaired hernia with an increase in the deposition of collagen type 1. The impact of doxycycline with porcine acellular dermal matrices (PADM) is unknown; therefore, we evaluated the impact of doxycycline administration upon hernia repair with PP and PADM mesh. METHODS: Sprague-Dawley rats weighing ~400 g underwent laparotomy with creation of a midline ventral hernia...

INTRODUCTION Large, complicated ventral hernias are an increasingly common problem. The transversus abdominis muscle release (TAMR) is a recently described modification of posterior components separation for repair of such hernias. We describe our initial experience with TAMR and sublay mesh to facilitate abdominal wall reconstruction. METHODS The study is a retrospective review of patients undergoing TAMR performed synchronously by gastrointestinal and plastic surgeons. RESULTS Twelve consecutive patients had their ventral hernias repaired using the TAMR technique from June 2013 to June 2014...
