BACKGROUND: Etiologies contributing to failure to wean from mechanical ventilation (MV) are multiple, resulting in morbid and costly outcomes. Diaphragm pacing (DP) is used in spinal cord injury to replace MV. Temporary DP could be utilized in acute respiratory failure to reduce MV. METHODS: A prospective FDA feasibility trial evaluated temporary DP electrodes implanted in each hemi-diaphragm during a subject's primary procedure. Objectives included: ability to provide ventilation, stability analysis with diaphragm electromyography, and adverse event monitoring...

BACKGROUND: Parastomal hernia repair (PHR) remains a challenge with no optimal repair technique. During retromuscular hernia repair, traversing the stomal conduit through the abdominal wall can result in angulation and compression. Widening of traditional cruciate incisions in mesh and/or fascia likely contributes to recurrences. To address these pitfalls, the Stapled Transabdominal Ostomy Reinforcement with Retromuscular Mesh (STORRM) technique utilizing a circular stapler was developed...

BACKGROUND: Transversus abdominis release (TAR) has evolved as an effective approach to complex abdominal wall reconstructions. Although the role of robotics in hernia surgery is rapidly expanding, the benefits of a robotic approach for abdominal wall reconstruction have not been established well. We aimed to compare the impact of the application of robotics to the TAR procedure on the perioperative outcomes when compared to the open TAR repairs. METHODS: Case-matched comparison of patients undergoing robotic TAR (R-TAR) at two specialized hernia centers to a matched historic cohort of open TAR (O-TAR) patients was performed...

INTRODUCTION: There continues to be debate regarding the best surgical technique for the treatment of paraesophageal hernias. While laparoscopic and robotic approaches are widely employed around the world, the benefits of mesh use to reinforce hiatal closure are still not well established. The goal of this manuscript is to describe the currently available results with biologic and bioabsorbable meshes for treatment of paraesophageal hernias, particularly with reference to the rate of recurrence...

BACKGROUND: Ventral hernia repair (VHR) is a frequent problem in the expanding aging population. However, advanced age is often viewed as a contraindication to elective hernia surgery. We aimed to analyze outcomes of VHR in a large cohort of elderly patients. We hypothesized that elective VHR is safe and effective even in patients over 70 years old. METHODS: We conducted a retrospective review of consecutive patients over the age of 70 who underwent VHR at a at a tertiary care hospital...

BACKGROUND: Despite patient risk factors such as diabetes and obesity, contamination during surgery remains a significant cause of infections and subsequent wound morbidity. Pressurized pulse lavage (PPL) has been utilized as a method to reduce bacterial bioburden with promising results in many fields. Although existing methods of lavage have been utilized during abdominal operations, no studies have examined the use of PPL during complex hernia repair. METHODS: Patients undergoing abdominal wall reconstruction (AWR) in clean-contaminated or contaminated fields with antibiotic PPL, from January 2012 to May 2013, were prospectively evaluated...

Breast reconstruction with a pedicled transverse rectus abdominis muscle (TRAM) flap can result in significant abdominal wall donor-site morbidity. Although the pedicled TRAM flap donor area reinforced with mesh results in decreased rates of postoperative abdominal bulging and hernias, the best technique to accomplish that is yet to be elucidated. We present our novel technique of posterior components separation with transversus abdominis muscle release and retromuscular mesh reinforcement for donor-area closure during pedicled TRAM flap breast reconstruction...

BACKGROUND: Contaminated operative fields pose significant challenges for surgeons performing ventral hernia repair. Although biologic meshes have been utilized increasingly in these fields, recent evidence suggests that synthetic meshes represent a viable option. We analyzed the outcomes of biologic and synthetic mesh utilized in patients undergoing major ventral hernia repair in clean-contaminated/contaminated fields. METHODS: We conducted a multicenter, retrospective review of patients undergoing open ventral hernia repair in clean-contaminated/contaminated fields using biologic or synthetic mesh...

Background Despite meticulous aseptic technique and systemic antibiotics, bacterial colonization of mesh remains a critical issue in hernia repair. A novel minocycline/rifampin tyrosine-coated, noncrosslinked porcine acellular dermal matrix (XenMatrix AB) was developed to protect the device from microbial colonization for up to 7 days. The objective of this study was to evaluate the in vitro and in vivo antimicrobial efficacy of this device against clinically isolated methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli...

BACKGROUND: Indications regarding hernia repair after removal of previously infected prostheses remain unclear. Patients may receive staged primary repair or single-stage reconstructions, neither of which may be ideal. Although animal models have simulated contamination by direct inoculation of implants with bacteria, there remains a paucity of literature, which simulates a field following mesh infection and removal. We aimed to develop a murine model to mimic this complex scenario to allow for further testing of various implants...

BACKGROUND: Optimal mesh reinforcement and operative technique for major abdominal wall reconstructions (AWR) remain debatable. Posterior component separation via transversus abdominis release (TAR) allows for wide sublay mesh reinforcement with durable reconstruction, and has been gaining popularity in recent years. Although biologic mesh has been associated with mixed results, outcomes of AWR with bioprosthetics have not been well elucidated to date. We evaluated our outcomes of TAR reconstructions with retromuscular porcine biologic mesh reinforcement...

Ventral hernia repair (VHR) in patients with inflammatory bowel disease (IBD) presents unique surgical challenges including impaired wound healing, concomitant intestinal operations, along with likely future abdominal surgeries. Appropriate techniques and mesh choices in these patients remain under active debate. Herein we report our experience with using a retromuscular approach for major VHR in a consecutive cohort of IBD patients. We identified all patients with IBD undergoing open VHR with retrorectus mesh placement between 2007 and 2013 in our prospectively maintained database...

BACKGROUND: Transversus abdominis plane block (TAPb) is an analgesic adjunct used for abdominal surgical procedures. Liposomal bupivacaine (LB) demonstrates prolonged analgesic effects, up to 72 hours. We evaluated the analgesic efficacy of TAPb using LB for patients undergoing open abdominal wall reconstruction (AWR). METHODS: Fifty patients undergoing AWR with TAPb using LB (TAP-group) were compared with a matched historical cohort undergoing AWR without TAPb (control group)...

BACKGROUND: Use of Enhanced Recovery After Surgery (ERAS) pathways have evidenced improved outcomes in several surgical specialties. The effectiveness of ERAS pathways specific to hernia surgery, however, has not yet been investigated. We hypothesized that our ERAS pathway would accelerate functional recovery and shorten hospitalization in patients undergoing open ventral hernia repair (VHR). STUDY DESIGN: Consecutive patients undergoing open major VHR using transversus abdominis release and sublay synthetic mesh placement, with use of our ERAS pathway, were compared with a historical cohort before ERAS implementation...

BACKGROUND: While mesh reinforcement is recognized as the optimal strategy for many hernia repairs, there remains debate on the optimal position for deployment and characteristics that lead to improved biocompatibility. Coatings are an avenue by which integration may be improved. Our aim was to evaluate tissue integration between uncoated, fibroblast- and mesenchymal stem cell-coated meshes placed as subcutaneous onlay (ON) or intraperitoneal underlay (UN). METHODS: Three commonly used biologic and synthetic hernia meshes were tested including Parietex, TIGR and Strattice...
