Background: Single-stage repair of incisional hernias in contaminated fields has a high rate of surgical site infection (30-42%) when biologic grafts are used for repair. In an attempt to decrease this risk, a novel graft incorporating gentamicin into a biologic extracellular matrix derived from porcine small intestine submucosa was developed.
Methods: This prospective, multicenter, single-arm observational study was designed to determine the incidence of surgical site infection following implantation of the device into surgical fields characterized as CDC Class II, III, or IV.
Results: Twenty-four patients were enrolled, with 42% contaminated and 25% dirty surgical fields. After 12 months, 5 patients experienced 6 surgical site infections (21%) with infection involving the graft in 2 patients (8%). No grafts were explanted.
Conclusions: The incorporation of gentamicin into a porcine-derived biologic graft can be achieved with no noted gentamicin toxicity and a low rate of device infection for patients undergoing single-stage repair of ventral hernia in contaminated settings.
Trial Registration: The study was registered March 27, 2015 at www.clinicaltrials.gov as NCT02401334.

Concurrent Panniculectomy With Abdominal Wall Reconstruction: A Propensity-scored Matched Study of Quality Improvement Outcomes.
Plast Reconstr Surg Glob Open
December 2024
Carolinas Medical Center, Charlotte, NC.
Background: Concurrent panniculectomy with abdominal wall reconstruction (CP-AWR) as a single-stage operation has reported increased complications, but constant quality improvement can improve results. This study describes outcomes for 21 years, impacted by evidence-based-practice changes.
Methods: Prospectively maintained database was reviewed for CP-AWR and separated by surgery date: "early" (2002-2016) and "recent" (2017-2023).
Management strategy of giant inguinoscrotal hernia-a case series of 24 consecutive patients surgically treated over 17 years period.
Hernia
December 2024
School of Medicine, University of Belgrade, 11000, Belgrade, Serbia.
Purpose: Management of giant inguinoscrotal hernia (GIH) is still a challenging procedure associated with a higher risk of intraabdominal hypertension and abdominal compartment syndrome as a life-threatening condition. The aim of the study was to present our management strategy for GIH.
Methods: This is a retrospective review of a case series including 24 consecutive patients with 25 GIH who underwent reconstructive surgery from January 2006 to June 2023, at the University Clinic for Digestive Surgery and Hernia Center Zuvela.

Pentalogy of Cantrell (PC) presents a distinctive challenge for clinicians and surgeons. In this case report, we have discussed the presentation, management, and literature review of a case of PC in a 17-month-old female child. The child was successfully managed with single-stage operation by a multidisciplinary team without any postoperative complications.

Department of Pediatric Surgery and Urology, Meyer Children's Hospital IRCCS, Viale Pieraccini 24, 50134, Florence, Italy.
Introduction: Urethrocutaneous fistula (UCF) is the most common complication after hypospadias repair, with an variable incidence of 2-35%, depending on defect type. The interposition of tissue between the neourethra and the skin or glans is considered an important factor to reduce the risk of UCF. Literature has focused on the comparison of different types of second layers, but there is still no consensus regarding the best tissue to adopt.

This is commonly associated with femoroacetabular impingement, particularly with cam deformities due to shearing of the cam on the acetabulum. Additionally, ACD associated with labral tears or chondrolabral separation, when untreated, can compromise labral repair outcomes.
