A E Engin, N Akkas
This paper, to the authors' best knowledge, presents the first attempt on the understanding of the biomechanics of hernial sac formation. First, a brief survey of the selected etiological factors and their related theories on hernia is given. Next, the results of some preliminary tensile tests conducted on normal and sac peritoneum are discussed. The third part of the paper is concerned with a theoretical model which incorporates both material and geometric nonlinearities by considering deformation of circular membrane under internal fluid pressure...

The fundamental mechanism for hernia formation is loss of the mechanical integrity of abdominal wall structural tissue that results in the inability to offset and contain intra-abdominal forces during valsalva and loading of the torso. There is evidence that genetic or systemic extracellular matrix disorders may predispose patients to hernia formation. There is also evidence that acute laparotomy wound failure leads to hernia formation and increases the risk of recurrent hernia disease. It may be that hernia formation is a heterogeneous disease, not unlike cancer, where one population of patients express an extracellular matrix defect leading to primary hernia disease, while other subsets of patients acquire a defective, chronic wound phenotype following failed laparotomy and hernia repairs...

The cause of primary groin hernia is multifactorial with evolutionary, hereditary, congenital, environmental aspects, and the general state of health all playing their part. Besides maintaining general body fitness and not smoking tobacco, there is little one can do to avoid this common affliction. On the other hand, recurrent groin hernia is largely due to easily controllable human factors and can be avoided by choosing an experienced surgeon with a particular interest and understanding of the subject, preferably one who specializes in and confines himself to the surgery of groin hernias, working in a unit dedicated to herniology he will select the best operation for the particular type of hernia and execute it to conform to the highest acceptable standards, using the best materials and techniques...

BACKGROUND: Incisional hernias occur commonly in up to 20% of all abdominal operations. Incisional hernia formation has been associated with increased levels of matrix metalloproteinases (MMPs), reduced collagen 1, and increased collagen 3 expression. Doxycycline, a nonspecific inhibitor of MMPs, has been shown to beneficially reduce MMP levels in both cancer and aneurysm models. This study evaluates the impact of doxycycline upon MMP expression, collagen subtypes, and hernia repair distraction forces in an animal model of incisional hernia repair...

Despite the continuous development of synthetic prosthetic meshes and their wide use, recurrent incisional hernias still appear in 5 to 20% of cases, with a linear incidence curve over the years, suggesting a multifactorial process rather than a simple failing technical repair as the underlying cause. Recent molecular biological research provide increasing evidence of connective tissue alterations such as a defective wound healing with impaired scarring process in patients with incisional hernia. Although there are some promising results, at present, in-depth understanding of the pathophysiological mechanisms and of the role that collagens play in the development and recurrence of incisional hernia is rather scarce...

PURPOSE: Epigastric herniation is a rather common condition with a reported prevalence up to 10 %. Only a minority is symptomatic, presumably the reason for the scarce literature on this subject. Epigastric hernias have specific characteristics for which several anatomical theories have been developed. Whether these descriptions of pathological mechanisms still hold with regard to the characteristics of epigastric hernia is the subject of this review. METHODS: A multi-database research was performed to reveal relevant literature by free text word and subject headings 'epigastric hernia', 'linea alba', 'midline' and 'abdominal wall'...

REVIEW
Robert Bendavid
The perusal of surgical journals suggests that the etiology and the treatment of hernias are still based on the understanding of a simple mechanical defect, an idiopathic happenstance requiring a reliable hernia repair, preferably with a prosthetic mesh or device. The need for additional elucidation does not constitute an aim that is pervasive in the surgical community or with the corporate manufacturers of surgical implements. This may well be because surgeons are not trained scientists and laboratory workers...

Michael G Franz
Abdominal wall hernias occur when tissue structure and function are lost at the load-bearing muscle, tendon, and fascial layer. The fundamental biologic mechanisms are primary fascial pathology or surgical wound failure. In both cases, cellular and extracellular molecular matrix defects occur. Primary abdominal wall hernias have been associated with extracellular matrix diseases. Incisional hernias and recurrent inguinal hernias more often involve a combination of technical and biologic limitations. Defects in wound healing and extracellular matrix synthesis contribute to the high incidence of incisional hernia formation following laparotomy...

Obturator hernia is a rare type of abdominal hernia that classically presents in elderly women. We report the case of 78-year-old woman with progressive vomiting, obstipation, and abdominal pain. Contrast-enhanced computed tomography showed a left-sided obturator hernia, which was confirmed and treated at laparotomy. Demographics, symptoms, imaging findings, and management of obturator hernias is reviewed.

Purpose Incisional hernia (IH) is common complication following laparotomy. Research suggests that the use of a prophylactic mesh can reduce the rate of IH. We performed an updated meta-analysis to better understand the evidence regarding prevention of IH using prophylactic mesh. METHODS: PubMed, clinictrials.gov.uk, and the Cochrane database were searched for randomised controlled trials comparing closure of the abdomen after laparotomy using a prophylactic mesh with suture closure. A meta-analysis was then performed...

PURPOSE: Although studies have implicated smoking as a positive predictor of post-operative outcomes in inguinal hernia repair, its impact on ventral hernia repair (VHR) is not as clear. This study aims to fill this gap by investigating the impact of smoking on developing adverse 30-day post-operative outcomes in VHR. METHODS: Patients undergoing VHR between 2005 and 2014 were extracted from the American College of Surgeons National Surgical Quality Improvement Program database...

PURPOSE: Parastomal hernias are challenging to manage, and an optimal repair has yet to be defined. An open, modified, retromuscular Sugarbaker technique has recently been described in the literature as a technically feasible approach to parastomal hernia repair. This study evaluates our initial institutional experience with parastomal hernia repair with the aforementioned technique with respect to safety and durability. METHODS: All patients who underwent an open, modified retromuscular Sugarbaker parastomal hernia repair from 2014 through 2016 at our institution were identified...

Hernia incidence has been observed since ancient time. Advancement in the medical textile industry came up with the variety of mesh materials to repair hernia, but none of them are without complications including recurrence of hernia. Therefore individuals once developed with the hernia could not lead a healthy and comfortable life. This drawn attention of surgeons, patients, researchers and industry to know the exact mechanism behind its development, complications and recurrence. Recent investigations highlighted the role of genetic factors and connective tissue disorders being the reason for the development of hernia apart from the abnormal pressure that is known to develop during other disease conditions...

Emergency repair of complicated abdominal wall hernias may be associated with worsen outcome and a significant rate of postoperative complications. There is no consensus on management of complicated abdominal hernias. The main matter of debate is about the use of mesh in case of intestinal resection and the type of mesh to be used. Wound infection is the most common complication encountered and represents an immense burden especially in the presence of a mesh. The recurrence rate is an important topic that influences the final outcome...

An obturator hernia is a rare condition and an unusual cause of intestinal obstruction. With a challenging diagnosis, it has one of the highest mortality rates of all abdominal wall hernias. The authors present a case of an elderly woman with bowel obstruction secondary to an incarcerated obturator hernia. An 80-year-old woman presented at the emergency room with complaints for the last 2 days of nausea, vomiting, constipation and lower right abdominal pain that radiated down to the right medial thigh. Abdominal tenderness to deep palpation of the right iliac fossa and mildly distention were noted...

INTRODUCTION: Operative management of complex ventral hernia still remains a significant challenge for surgeons. Closure of large defects in the unprepared abdomen has serious pathophysiological consequences due to chronic contraction and retraction of the lateral abdominal wall muscles. We report outcomes of 56 consecutive patients who had preoperative Botulinum toxin A (BTA) abdominal wall relaxation facilitating closure and repair. METHODS: This was a prospective observational study of 56 patients who underwent ultrasound-guided BTA into the lateral abdominal oblique muscles prior to elective ventral hernia repair between November 2012 and January 2017...
