Nerve degeneration in inguinal hernia specimens
2011
BACKGROUND: The histological study of the herniated inguinal area is rare in the literature. This report is focused on the detection of structural changes of the nerves within tissues bordering the inguinal hernia of cadavers. Their physiopathological consequences are hypothesized. MATERIALS AND METHODS: Primary inguinal hernia was diagnosed in 30 fresh cadavers. Tissue specimens from the inguinal region close to and around the hernia opening were excised for histological examination. A control of the data was achieved through tissue samples excised from equivalent sites of the inguinal region in 15 cadavers without hernia. RESULTS: The detected nerves in the inguinal area demonstrated path…
Inguinal hernia and certain risk factors
1992
There are several studies on inguinal hernias that give some clues about the association between this type of hernia and certain risk factors. This association was suspected long ago but had not been demonstrated. The present study tries to correlate the origin of inguinal hernias and the physical effort of the subjects in accordance with their work activity. The results of this study show that physical effort, as a risk factor, is closely related to the appearance of inguinal hernias. A person whose work involves lifting or other strenuous exertion has a higher risk than those whose jobs are less strenuous (p less than 0.05). This conclusion was reached after taking into account not only t…
Enhanced angiogenesis in the 3D dynamic responsive implant for inguinal hernia repair ProFlor
2021
Biologic response to hernia prostheses represents a continuous source of debate. Conventional hernia meshes, in their typical static, passive configuration have been used for decades to reinforce the herniated abdominal wall. These flat implants, mainly fixated with sutures or tacks, induce poor quality fibrotic ingrowth that shrinks the mesh. In groin hernia repair, flat meshes are applied in the delicate inguinal surrounding where uncontrolled development of a scar plate can impair movement and may incorporate the sensitive nerves crossing this area. Complications deriving from mesh fixation and nerve entrapment are frequent and unpleasant for patients. To remedy these problems, a multila…
Sphincter-like motion following machanical dilation of the internal inguinal ring during indirect inguinal hernia procedure
2008
INTRODUCTION: Even today, there is still great speculation as to the underlying pathogenesis of inguinal hernia. As a result, it could be extrapolated that the vast majority of repairs are based upon conjecture. Most current repairs are founded upon the principle of "closing the defect" in the anatomy, either by suturing closed under tension, covering with a mesh or obliterating the defect with a plug. Many variants of each method are refined to achieve better clinical outcomes. Yet few, if any, strive to understand a fundamental question: "What has gone wrong with the normal physiological and anatomical mechanisms that prevent abdominal structures protruding through the abdominal wall?" We…
AMYAND’S HERNIA, AN UNKNOWN ENTITY THAT MAY CAUSE SURGEONS DIFFICULTY: OUR EXPERIENCE AND LITERATURE REVIEW
2021
The aim of this case report is to present an uncommon disease, Amyand’s hernia. It is an inguinal hernia containing the appendix in the hernial sac. The authors describe this condition analysing a clinical case and reporting a literal review which points out preoperative and intraoperative management.
Biologic response of inguinal hernia prosthetics: a comparative study of conventional static meshes versus 3D dynamic implants.
2015
Despite improvements in prosthetics and surgical techniques, the rate of complications following inguinal hernia repair remains high. Among these, discomfort and chronic pain have become a source of increasing concern among surgeons. Poor quality of tissue ingrowth, such as thin scar plates or shrinking scars-typical results with conventional static implants and plugs-may contribute to these adverse events. Recently, a new type of 3D dynamically responsive implant was introduced to the market. This device, designed to be placed fixation-free, seems to induce ingrowth of viable and structured tissue instead of regressive fibrotic scarring. To elucidate the differences in biologic response be…
Inguinal Hernia: Defect Obliteration with the 3D Dynamic Regenerative Scaffold Proflor™.
2021
Prosthetic inguinal hernia repair presents significant challenges. Some of these, such as mesh fixation and quality of the biologic response, are still debated among surgeons. For example, there is no strong consensus regarding a specific condition that characterizes the surgical procedure during herniorrhaphy. This issue concerns management of the hernia defect, which in conventional hernia repair with flat meshes remains patent. However, a critical analysis of typical postoperative complications after inguinal hernia repair reveals that some of these adverse events are related to patency of the hernial opening. Postoperative discomfort, pain with specific movements and even hernia recurre…
Dynamic autostatic implant for inguinal hernia repair. Early results in an explorative cohort of patients
2010
Acknowledging the need to further improve outcomes and reduce complications in inguinal hernia repair, our group has been developing new surgical implants for this condition. Our primary considerations are to reduce complications associated with invasive fixation, and improve the quality of the tissue ingrowth within the implant. We have developed a new type of 3D dynamic, self retaining implant to achieve these effects. This newly designed implant was previously experimentally tested in porcine model, showing excellent outcomes. Above all, the results concerning the quality of tissue ingrowth and the nearby absence of shrinkage in the long term were excellent. In this report we describe th…
Inguinal hernia: The destiny of the inferior epigastric vessels and the pathogenesis of the disease
2020
While many scientific reports deal with inguinal hernia, including treatment methods and prosthetic devices proposed to provide a cure, few studies have sought to deepen our understanding of the etiology of this disease. The genesis of inguinal protrusion seems to be a neglected subject, even though addressing hernia genesis may be helpful for improving techniques and materials for surgical treatment. To clarify the source of inguinal protrusions, macroscopic and histological alterations of the inferior epigastric vessels in the herniated groin have been studied. These vascular structures exhibit significant features that could help to illuminate hernia genesis.In patients with double ipsil…
Fixation-free inguinal hernia repair using a dynamic self-retaining implant.
2012
Inguinal hernia repair remains controversial, despite advances in technique and materials. Conventional implants are typically static (passive) and do not move in concert with the groin's motility. Inguinal hernia repair with mesh fixation on dynamic groin structures are not tension free, and are associated with tissue tearing, bleeding, hematoma, and nerve entrapment--all which might contribute to mesh dislocation. The poor quality of tissue ingrowth within static meshes/plugs embodies another crucial issue in prosthetic hernia repair. Because the prosthetics used for inguinal hernia repair are incorporated by rigid fibrotic tissue (hence the term "scar plate"), the regressive tissue leads…
