Veterinary pathologists commonly encounter lesions of blunt trauma. The development of lesions is affected by the object's mass, velocity, size, shape, and angle of impact and by the plasticity and mobility of the impacted organ. Scrape, impact, and pattern abrasions cause localized epidermal loss and sometimes broken hairs and implanted foreign material. Contusions are best identified after reflecting the skin, and must be differentiated from coagulopathies and livor mortis. Lacerations-traumatic tissue tears-may have irregular margins, bridging by more resilient tissue, deviation of the wound tail, crushed hairs, and unilateral abrasion...

UNLABELLED: A critical challenge in tissue regeneration is to develop constructs that effectively integrate with the host tissue. Here, we describe a composite, laser micromachined, collagen-alginate construct containing human mesenchymal stem cells (hMSCs) for tissue repair applications. Collagen type I was fashioned into laminated collagen sheets to form a mechanically robust fascia that was subsequently laser micropatterned with pores of defined dimension and spatial distribution as a means to modulate mechanical behavior and promote tissue integration...

The term Neuromuscular and Vascular Hamartoma (NMVH) was initially coined by Fernando and McGovern in 1982 in their report of 2 cases. Whether this lesion is truly hamartomatous or represents a "burnt-out" phase of varying chronic pathologies has been debated since that time. Examples of NMVH-like proliferations have been reported in the setting of diaphragm disease, Crohn's disease, radiation, and ischemia. Herein we present the case of a 73-year-old female with partial small bowel obstruction and a past surgical history significant for cholecystectomy and abdominal hysterectomy...

Vaginal cuff dehiscence is a rare, but potentially morbid, complication of total hysterectomy and refers to separation of the vaginal cuff closure. The term vaginal cuff dehiscence is frequently interchanged with the terms of cuff separation or cuff rupture. All denote the separation of a vaginal incision that was previously closed at time of total hysterectomy. After dehiscence of the vaginal cuff, abdominal or pelvic contents may prolapse through the vaginal opening. Bowel evisceration, outside the vulvar introitus, can lead to serious sequelae, including peritonitis, bowel injury and necrosis, or sepsis...

OBJECTIVE: Ventral incisional hernia is a common complication of abdominal surgery. The marked improvements in medical technology and healthcare, lead to an increasing number of elderly patients to take advantage of even complex surgical procedures. The objective of this literature review was to analyze the risk factors for ventral incisional hernia in elderly patients and to identify measures that might decrease the incidence of this complication. MATERIALS AND METHODS: An analysis of the surgical literature was performed using the search engines EMBASE, Cochrane Library, and PubMed with particular reference to elderly patients using the keywords: abdominal hernia, wound dehiscence, incisional hernia, incidence, trocar site hernia, and hernia prevention...

Cutaneous collagenous vasculopathy (CCV) is a rare distinct idiopathic microangiopathy of the superficial cutaneous vasculature. Seven new cases are reported (6 females and 1 male) ranging in age from 42 to 85 years, with some showing unusual clinical and histopathological findings. All presented with macular telangiectases starting on the lower extremities and spreading progressively in 5 cases and were suspected to have generalized essential telangiectasia. Two cases had a history of over 20 years. One case had lesions in the abdominal striae, and 1 was markedly ecchymotic...

The design of meshes for the treatment of incisional hernias could benefit from better knowledge of the mechanical response of the abdominal wall and how this response is affected by the implant. The aim of this study was to characterise the mechanical behaviour of the human abdominal wall. Abdominal walls were tested ex vivo in three states: intact, after creation of a defect simulating an incisional hernia, and after reparation with a mesh implanted intraperitonally. For each state, the abdominal wall was subjected to air pressure loading...

The results of clinical and experimental morphological studies of regenerates forming after replacement of large defects of the abdominal wall and tibia with implants from different materials (polytetrafluoroethylene, reperene, prolene, titanium, and titanium nickelide) are analyzed. Study of the regenerate histology and fibroarchitectonics has shown good prospects of mesh constructions from titanium nickelide for effective surgical repair of these defects. The use of this implant seems to be theoretically well-based and promising, particularly under conditions of suppurative infection and low individual reparative regenerative potential...

Management of complex abdominal defects remains a significant challenge for many surgeons, especially in contaminated fields. Currently, available biosynthetic grafts include human cadaveric dermis (AlloDerm), porcine dermal (Permacol and Strattice), and submucosal (Surgisis) sources. All these grafts are composed of an acellular collagen scaffold to provide a bridge for tissue incorporation and neovascularization. The authors describe a case report of a woman who required dual mesh explantation and successive reparative surgery using a porcine dermal matrix for a complex and infected abdominal wound...

In cases of giant omphalocele anterior abdominal wall is so poorly developed that primary closure is not possible without excessive tension. The simplest of innovative strategies in such a situation is to provide epithellalisation of sac with secondary closure of ensuing ventral hernia at a later date. Postsurgical chylous ascites is a known entity and it usually responds with supportive therapy. Chylous ascites as a complication of reparative surgery of exomphalos is rare. Here a case of complete resolution of chylous ascites following conservative therapy who underwent a repair of ventral hernia as a sequela to non-operative treatment of giant omphalocele is reported...

The use of nonabsorbable prosthetic materials such as polypropylene, polyester, and ePTFE, have expanded and are now widely used in reparative surgery for abdominal wall hernias.There are still difficulties to find correct indication for prosthetic implant in emergency hernia surgery: as a matter of fact there is still a great debate if to use non-absorbable prostheses in potentially or truly infected operating fields [e.g. after intestinal resections].All these problems can be avoided with the use of absorbable prosthetic materials such as those composed of lactic acid polymers or lactic and glycolic acid copolymers: however, the use of these absorbable prosthesis exposes the patient to a rapid and inevitable hernia recurrence...

BACKGROUND: The syndecan family of cell surface proteoglycans can bind and modulate the activity of a diverse group of soluble and insoluble ligands, which have been shown to modulate events relevant to acute tissue repair and chronic injury responses. The expression of members of the syndecan family of heparan sulfate proteoglycans during the course of aortic aneurysm formation has not been previously investigated. In this investigation, the spatiotemporal expression of syndecan-1, -2, and -4 was characterized in a murine model of aneurysm formation...

OBJECTIVE: Vacuum-assisted wound closure (VAC) exposes the wound bed to negative pressure, resulting in removal of edema fluid, improvement of blood supply, and stimulation of cellular proliferation of reparative granulation tissue. It has been used to treat open wounds in the extremities, open sternal wounds, pressure ulcers, and abdominal wall wounds. This study retrospectively reviewed instrumented spine fusions complicated by surgical wound infection and managed by a protocol including the use of VAC in order to evaluate the efficacy of applying vacuum therapy on patients with deep spine infections and exposed instrumentation...

Large defects of abdominal wall (greater than 8 cm in diameter) related to different cause, are still difficult problem of modern surgery. The best results in order to obtain safe and permanent anatomical and functional abdominal wall integrity are reached by autogenous dermal and synthetic grafts. Controversies concerning quality of these procedures are still presents. Our work is based on two equal experimental groups of 20 Vister rats each, with large artificial abdominal wall defects: one treated with autogenous dermal graft, another with synthetic Mersilene mesh graft...

BACKGROUND CONTEXT: Destabilization of the lumbar spine results from sacrifice of the anterior longitudinal ligament and disc when removed for graft or cage placement. In a similar fashion, transection of the interspinous ligament during surgical approaches to the posterior spine may result in segmental instability. Such instability can cause abnormal motion or implant migration resulting in a higher incidence of pseudarthrosis. Small intestinal submucosa (SIS) is a naturally occurring extracellular collagen-based matrix, which is derived from porcine small intestine...

Peculiarities of penetration of living bacterial cultures of Bacillus strain into the structures of the abdominal wall, their positive influence upon the reparative regeneration of surgical wounds were studied in experiments in 240 rats. It was found the living bacterial preparation to be expedient to use as an antagonist of pyogenic infection for purulent postoperative wounds and in order to prevent its development. The clinical antiinflammatory and stimulating the reparative process effects of sporobacterin were studied in 50 patients with infectious wound complications after urgent and scheduled operations...

We report a 74-year-old man with triple synchronous cancers occurring in the gallbladder, common bile duct, and pancreas. The patient had consulted a nearby physician because of epigastralgia and icterus. On September 30, 1997, the patient was admitted to our department for further evaluation and treatment. Abdominal computed tomography (CT) showed dilatation of the common bile duct, cystic duct, and intrahepatic bile duct, and swelling of the gallbladder. On CT, the wall of the distal common bile duct was thick and a low-density mass was detected on the left side...

Mesh implantation to repair incisional hernia involves extensive disturbance of the integrity of the abdominal wall. To define the physiological requirements, we measured the elasticity of the abdominal wall of 14 anatomic samples. The complete abdominal wall was excised and stretched at a strain of 0-24 N in horizontal, vertical and oblique (upper and lower abdomen) directions. The resulting mean distension at 16 N was in the range between 11% and 32% for all directions. Furthermore, we found significant differences between tissue samples from male and female subjects, as well as considerable inter-individual differences in each group...
