BACKGROUND: Flank and lumbar hernias (FLH) are challenging to repair. This study aimed to establish a reproducible management strategy and analyze elective flank and lumbar repair (FLHR) outcomes from a single institution. METHODS: A prospective analysis using a hernia-specific database was performed examining patients undergoing open FLHR between 2004 and 2021. Variables included patient demographics and operative characteristics. RESULTS: Of 142 patients, 106 presented with flank hernias, and 36 with lumbar hernias...

Surgical approaches for pelvic organ prolapse have evolved over the last 30 years and is a popular topic for debate, particularly when discussing apical prolapse. Transvaginal native tissue repairs remain the mainstay of POP surgeries, however, transabdominal approaches continue to evolve. Use of interposition material, such as synthetic polypropylene mesh, is the standard when performing an abdominal sacrocolpopexy, however, use of autologous fascia can be considered. This debate article provides an overview of this subject and highlights the value of different approaches to apical prolapse...

In recent years, deep learning (DL) has shown great potential in the field of dermatological image analysis. However, existing datasets in this domain have significant limitations, including a small number of image samples, limited disease conditions, insufficient annotations, and non-standardized image acquisitions. To address these shortcomings, we propose a novel framework called DermSynth3D. DermSynth3D blends skin disease patterns onto 3D textured meshes of human subjects using a differentiable renderer and generates 2D images from various camera viewpoints under chosen lighting conditions in diverse background scenes...

PURPOSE: The suburethral sling procedure has been widely used as the first-line treatment for female stress urinary incontinence (SUI). This study retrospectively compared the long-term surgical outcomes and complications between retropubic and transobturator suburethral sling procedures. METHODS: From 2010 to 2022, a total of 533 women with SUI underwent retropubic pubovaginal sling (PVS) or transobturator tape (TOT) procedures using a synthetic polypropylene mesh with or without concomitant anterior colporrhaphy...

BACKGROUND: The use of mesh is standard of care for large ventral hernias repaired on an elective basis. The most used type of mesh includes synthetic polypropylene mesh; however, there has been an increase in the usage of a new polyester self-gripping mesh, and there are limited data regarding its efficacy for ventral hernia. The purpose of the study is to determine whether there is a difference in surgical site occurrence (SSO), surgical site infection (SSI), surgical site occurrence requiring procedural intervention (SSOPI), and recurrence at 30 days after ventral hernia repair (VHR) using self-gripping (SGM) versus non-self-gripping mesh (NSGM)...

Large open chest wall wounds can be difficult to manage due to full-thickness tissue loss with underlying rib fractures and exposed lung parenchyma. Historically, the use of synthetic material has been discouraged in the traumatic setting with the concern that it may be associated with an increased risk of infection. We present 4 patients with large open injuries to the thorax-one from blunt and three from penetrating trauma. We describe our initial management followed by prompt surgical repair using biologic mesh, titanium rib spanning plates, and rotational tissue flaps with Z-plasty of the skin for definite closure...

While numerous types of chemical cosmetic cleansers have been presented, those with sensitive skin may still experience some irritation while using them. Moreover, the environmental issue of chemical agents has been documented repeatedly. To address these, we suggest the potential application of a micro-sized bubble-laden water jet to cleanse the cosmetics without (or less) using chemical detergents. We devised a venturi-type nozzle with a mesh and air holes capable of generating massive fine bubbles. By testing with the foundation and lip tint (known to be highly adhesive) coated on the synthetic leather and artificial skin surfaces, we measured that the cleansing performance of the bubbly jet is much better (even without the chemical agent) than the single-phase liquid jet...

PURPOSE: Due to the reclassification of transvaginal mesh as a high-risk device, there has been renewed interest in the use of fascia lata in pelvic floor reconstruction. Here we report our experience in 108 patients who underwent large fascia lata harvest for pelvic organ prolapse (POP) repair. Our primary objective was to highlight the postoperative morbidity of the large fascia lata harvest in patients who underwent POP repair using fascia lata autograft. METHODS: Surgery involved harvesting a fascia lata graft through a small lateral upper thigh incision and was used for either autologous transvaginal POP repair or autologous sacrocolpopexy...

Size spectra analysis has been widely used to study pelagic ecosystems worldwide. It has a solid theoretical and empirical basis and can be used to provide useful information on ecosystem structure and trophic efficiency. The objective of this study was to obtain complete Normalized Biovolume Size Spectra (NBSS), including zooplankton, microplastics, and other suspended particles, along an estuary-shelf gradient. Plankton net samples (300 μm mesh) were obtained in the Rio Formoso Estuary, in Tamandaré Bay and on the continental shelf off Tamandaré, Brazil, during two years (from April/2013 to May/2015)...

INTRODUCTION: Abdominal surgery following transversus abdominis release (TAR) procedure commonly involves incisions through the previously implanted mesh, potentially creating vulnerabilities for hernia recurrence. Despite the popularity of the TAR procedure, current literature regarding post-AWR surgeries is limited. This study aims to reveal the incidence and outcomes of post-TAR non-hernia-related abdominal surgeries of any kind. METHODS: Adult patients who underwent non-hernia-related abdominal surgery following ventral hernia repair with concurrent TAR procedure and permanent synthetic mesh in the Cleveland Clinic Center for Abdominal Core Health between January 2014 and January 2022 were queried from a prospectively collected database in the Abdominal Core Health Quality Collaborative...

BACKGROUND: Abdominal wall deficiencies or weakness are a common complication of temporary ostomies, and incisional hernias frequently develop after colostomy or ileostomy takedown. The use of synthetic meshes to reinforce the abdominal wall has reduced hernia occurrence. Biologic meshes have also been used to enhance healing, particularly in contaminated conditions. Reinforced tissue matrices (RTMs), which include a biologic scaffold of native extracellular matrix and a synthetic component for added strength/durability, are designed to take advantage of aspects of both synthetic and biologic materials...

Radical sternectomy with sternal reconstruction using synthetic mesh or titanium plates has been described before with excellent results. However, radical removal of the sternum without reconstruction is a rare surgical treatment for complicated deep sternal wound infections (DSWI). The long-term outcome following this radical operation is not well-known due to the limited number of cases in the literature. We report on a patient 10 years after a radical sternectomy for DSWI who presented with shortness of breath...

INTRODUCTION: Both biologic and permanent (synthetic) meshes are used for abdominal wall reconstruction. Biologic mesh has the advantage of eventual incorporation, which makes it generally preferred in contaminated patients compared with synthetic mesh (Ann Surg. 2013;257:991-996). However, synthetic mesh has been shown to have decreased long-term hernia recurrence despite increased complications (JAMA Surg. 2022;157:293-301). Ovitex (TelaBio, Ltd, Auckland, New Zealand) is a combined reinforced biologic mesh with a permanent Prolene suture weave that theoretically combines incorporation with a long-term strength component...

INTRODUCTION: The ideal mesh type for hernia repair in a contaminated field remains controversial. Data regarding outcomes beyond 1 year and the impact on quality of life (QoL) are unknown. This study aims to evaluate the long-term surgical outcomes and patient-reported outcomes (PROs) after contaminated repair with poly-4-hydroxybutyrate (P4HB) mesh. MATERIALS METHODS: Patients undergoing a contaminated hernia repair with P4HB between 2015 and 2020 were identified...

Computational fluid dynamics (CFD) is a valuable asset for patient-specific cardiovascular-disease diagnosis and prognosis, but its high computational demands hamper its adoption in practice. Machine-learning methods that estimate blood flow in individual patients could accelerate or replace CFD simulation to overcome these limitations. In this work, we consider the estimation of vector-valued quantities on the wall of three-dimensional geometric artery models. We employ group-equivariant graph convolution in an end-to-end SE(3)-equivariant neural network that operates directly on triangular surface meshes and makes efficient use of training data...

INTRODUCTION: Surgical treatment of type I hiatal sliding hernias aims to control the gastroesophageal reflux symptoms and prevention of hernia recurrence. Usually, a cruroplasty is performed to narrow the hiatal orifice. Here, it remains controversial if a mesh reinforcement of the cruroplasty should be performed, since benefits as well as mesh-associated complications have been described. METHODS: We performed a propensity-score matching analysis with data derived from the Herniamed registry comparing patients undergoing laparoscopic type I hiatal hernia repair with and without synthetic mesh...

INTRODUCTION: Incisional hernias with a defect width of more than10 cm are considered complex. The European Hernia Society guidelines recommend that such hernias should only be repaired by surgeons with experience of component separation. The standard component separation technique now is posterior component separation with transversus abdominis release (PCSTAR). Questions are raised about the limits of this technique. METHODS: A literature search of publications on PCSTAR was performed for any references to the limits of this technique in open incisional hernia repair...

PURPOSE: Repair of midline ventral incisional hernias (VIHR) requires mesh reinforcement. Mesh types can be categorised into synthetic, biosynthetic, or biological. There is a lack of evidence to support one type of mesh over another. The aim of this pilot study was to compare mesh sensation in patients having undergone elective open repair with synthetic or biosynthetic mesh. METHODS: Four years of prospectively collected data were retrospectively reviewed on 40 patients who had undergone VIHR, using either biosynthetic or synthetic mesh placed in the retromuscular plane...

Implant-based breast reconstruction (IBBR) is the most frequently performed procedure for breast reconstruction following mastectomy, which involves the surgical placement of breast implants. The approach to breast reconstruction can be divided into two main categories, namely prepectoral breast reconstruction (PPBR) and subpectoral breast reconstruction (SPBR), based on the implant plan and placement technique. In recent years, there has been a significant surge in the popularity of prepectoral implant-based breast reconstruction, where the implants are positioned above the chest muscle, as opposed to beneath it in the subpectoral approach...
