Hernia

OBJECTIVE: To review mesh products currently available for ventral hernia repair and to evaluate their efficacy in complex repair, including contaminated and reoperative fields. BACKGROUND: Although commonly referenced, the concept of the ideal prosthetic has never been fully realized. With the development of newer prosthetics and approaches to the ventral hernia repair, many surgeons do not fully understand the properties of the available prosthetics or the circumstances that warrant the use of a specific mesh...

INTRODUCTION: The concept of using a mesh to repair hernias was introduced over 50 years ago. Mesh repair is now standard in most countries and widely accepted as superior to primary suture repair. As a result, there has been a rapid growth in the variety of meshes available and choosing the appropriate one can be difficult. This article outlines the general properties of meshes and factors to be considered when selecting one. MATERIALS AND METHODS: We performed a search of the medical literature from 1950 to 1 May 2009, as indexed by Medline, using the PubMed search engine (www...

OBJECTIVE: In this systematic review, we evaluated all literature reporting on the surgical treatment of primary epigastric hernias, primarily focusing on studies comparing laparoscopic and open repair, and mesh reinforcement and suture repair. METHODS: A literature search was conducted in Embase.com, PubMed and the Cochrane Library up to 24 April 2019. This review explicitly excluded literature on incisional hernias, ventral hernias not otherwise specified, and isolated (para)umbilical hernias...

PURPOSE: In July 2013, the World Society of Emergency Surgery (WSES) held the first Consensus Conference on emergency repair of abdominal wall hernias in adult patients with the intention of producing evidence-based guidelines to assist surgeons in the management of complicated abdominal wall hernias. Guidelines were updated in 2017 in keeping with varying clinical practice: benefits resulting from the increased use of biological prosthesis in the emergency setting were highlighted, as previously published in the World Journal of Emergency Surgery...

BACKGROUND: Abdominal wall reconstruction in patients presenting with enteric fistulas and mesh infection is challenging. There is a consensus that synthetic mesh must be avoided in infected operations, and the alternatives to using synthetic mesh, such as component separation techniques and biologic mesh, present disappointing results with expressive wound infection and hernia recurrence rates. METHODS: A prospective clinical trial designed to evaluate the short- and long-term outcomes of 40 patients submitted to elective abdominal wall repair with synthetic mesh in the dirty-infected setting, and compared to a cohort of 40 patients submitted to clean ventral hernia repairs...

PURPOSE: In a subset of patients with massive and multiply recurrent hernias, despite performing a transversus abdominis release (TAR), anterior fascial re-approximation is not feasible and a bridged repair is required. We aim to report on the outcomes of this patient population at our institution. METHODS: Patients that underwent a TAR-bridged repair at the Cleveland Clinic were identified retrospectively within the Americas Hernia Society Quality Collaborative (AHSQC) database...

Management of incarcerated hernias is a common issue facing general surgeons across the USA. When hernias are not able to be reduced, surgeons must make decisions in a short time frame with limited options for patient optimization. In this article, we review assessment and management options for incarcerated ventral and inguinal hernias.

BACKGROUND: Incisional hernias are a common complication of emergency laparotomy and are associated with significant morbidity. Recent studies have found a reduction in incisional hernias when mesh is placed prophylactically during abdominal closure in elective laparotomies. This systematic review will assess the safety and efficacy of prophylactic mesh placement in emergency laparotomy. METHODS: A systematic review was performed according to the PROSPERO registered protocol (CRD42018109283)...

PURPOSE: The purpose of this paper is to communicate two new concepts with the potential to cause major morbidity in hernia repair, effective porosity and biofilm. These 2 concepts are interrelated and have the potential to result in mesh-related complications. Effective porosity is a term well described in the textile industry. It is best defined as the changes to pore morphology after implantation of mesh in situ. It is heavily dependent on mesh construct and repair technique and has the potential to impact hernia repair by reducing mesh tissue integration and promoting fibrosis...

OBJECTIVE: This article analyzes radiopaque properties of meshes currently used in hernia surgery. A search was conducted using PubMed and a combination of the terms "hernia repair," "mesh," "laparoscopy," "CT," "MRI," "radiopaque," and "high-resolution techniques." CONCLUSION: The visibility of meshes varies from not visible at all (e.g., Ultrapro), to hardly discernible (Prolene), to readily seen (Composix), and finally to the always visible (Dualmesh)...

Abdominal hernia is a common disease, and the most effective treatment of it is using surgical meshes. However, it was found that due to the mismatch of the mechanical properties between the mesh and the tissues around the hernia, there was still a recurrence rate of more than 33% and a high probability of postoperative discomfort. Currently, because of the complex mechanical environment provided by the abdominal tissues and the lack of quantitative research, it is still difficult to select a mesh with suitable mechanical properties for a hernia with specific position and size...

BACKGROUND: Component Separation (CST) typically involves incision of one or more fascial planes to generate myofascial advancement flaps to assist with fascial closure in ventral hernia repair (VHR). The aim of this study was to compare peri-operative outcomes and quality of life (QOL) after CST versus patients without CST (No-CST) in large, preperitoneal VHR (PPVHR). METHODS: A prospective, single institution hernia study examined all patients undergoing PPVHR with synthetic mesh...

BACKGROUND: Pathways of enhanced recovery after surgery represent a standardized, multimodal approach to postoperative care with the goal of accelerating recovery without increasing morbidity. We hypothesized that implementation of an enhanced recovery after surgery pathway for abdominal wall reconstruction would result in a decreased duration of stay. METHODS: We compared 100 historic controls to 100 consecutive patients undergoing abdominal wall reconstruction with use of a newly implemented, enhanced recovery after surgery pathway to detect a difference in duration of stay of 1 day...

BACKGROUND: The abdominal wall can be considered comprised of two compartments: an anterior and a posterior compartment. The anterior compartment includes the anterior rectus sheath and the rectus muscle. The posterior compartment comprises the posterior rectus sheath, the transversalis fascia, and the peritoneum. When a large defect in the anterior compartment has to be corrected, for example, a rectus diastasis or large incisional hernia, an action on the anterior compartment is necessary; therefore, an anterior component separation has to be considered...

BACKGROUND: Patient engagement is an increasingly important component of surgical decision making. Given the many factors associated with successful ventral hernia repair (VHR), we developed and validated the Outcomes Reporting App for Clinical and Patient Engagement (ORACLE) tool to help facilitate preoperative surgeon-patient discussions about VHR. METHODS: All patients undergoing elective, VHR with 30-day follow-up data available within the Americas Hernia Society Quality Collaborative were eligible for study inclusion...

BACKGROUND: Component separation technique involves incision of abdominal muscle and its aponeurosis, which generates a myofascial advancement flap to assist with fascial closure in abdominal wall reconstructions. This tissue mobilization allows for musculo-fascial approximation of much larger abdominal wall defects than would otherwise be possible. With extensive tissue mobilization, however, there is concern for significant wound and systemic complications. METHODS: A prospective, single institution hernia database was queried for patients undergoing component separation from January 2006 to May 2018...

INTRODUCTION: Incisional hernia (IH) is a common postoperative complication that affects 10% of the patients who undergo abdominal surgery. The component separation (CS) technique is suitable for large and/or complex hernias; however, CS alone may not eliminate recurrence and is associated with an increased incidence of wound complications. Self-gripping mesh enhances tissue adhesion and contributes to a reduced risk of migration, chronic pain, and other complications. Here, we present three cases of IH that were successfully repaired by anterior CS (ACS) using onlay self-gripping meshes...

UNLABELLED: In 2014 the International Endohernia Society (IEHS) published the first international "Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias". Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature...

Closure of large abdominal-wall defects usually requires the transposition of remote myocutaneous flaps or free-tissue transfers. The purpose of this study was to determine if separation of the muscle components of the abdominal wall would allow mobilization of each unit over a greater distance than possible by mobilization of the entire abdominal wall as a block. The abdominal walls of 10 fresh cadavers were dissected. This demonstrated that the external oblique muscle can be separated from the internal oblique in a relatively avascular plane...
