Aortic graft infection is one of the most serious complications of aortovascular surgery. Diagnosis is based on clini-cal and radiologic findings. The emphasis is put on early diagnosis and its impact on prognosis of patients. The management should be individualized. The gold standard is surgical treatment with complete excision of the infected foreign material with debridement of the surrounding tissue and repair of vascular continuity by extra-anatomic bypass or in situ bypass with autologous femoral vein or cryopreserved arterial allografts...

While surgical site preparation has been extensively studied, there is little information about resistance of skin microbiota in the biofilm form to antimicrobial decontamination, and there are no quantitative models to study how biofilm might be transferred into sterile tissue/implant materials during injections for joint spine and tendon, aspiration biopsies and dermal fillers (DF). In this work, we develop two in vitro models to simulate the process of skin preparation and DF injection using pig skin and SimSkin (silicone) materials, respectively...

BACKGROUND Surgery remains the mainstay of gastric cancer treatment. It is, however, associated with a relatively high risk of perioperative complications. The use of laparoscopy and the Enhanced Recovery After Surgery (ERAS) protocol allows clinicians to limit surgically induced trauma, thus improving recovery and reducing the number of complications. The aim of the study is to present clinical outcomes of patients with gastric cancer undergoing laparoscopic gastrectomy combined with the ERAS protocol. MATERIAL AND METHODS Fifty-three (21 female/32 male) patients who underwent elective laparoscopic total gastrectomy due to cancer were prospectively analyzed...

INTRODUCTION: Single-port laparoscopic surgery has some technical limitations with respect to control of the forceps inserted through the single-access site, which results in increased internal collisions due to coaxial alignment of the instruments, as well as and decreased range of motion and visualization. To overcome these limitations, we employ a "modified marionette technique" as a way to carry out laparoscopic colorectal surgery. Materials and Surgical Technique: The procedures for the modified marionette technique are performed as follows: An Internal Organ Retractor (IOR)™ and an atraumatic clip designed to firmly grasp tissue, with 1-0 nylon thread, are inserted through a 12-mm trocar and secured in place where adequate visualization and traction for cutting with a radio knife is required...

To our knowledge, proximal tibiofibular joint instability has never been reported in a patient with a total knee arthroplasty (TKA). We present the case of a patient with anterolateral proximal tibiofibular joint instability associated with a complex primary TKA. In 2010, a male patient of 47 years was referred for TKA after posttraumatic osteoarthritis. The patient's history includes a fracture of the left lateral tibial plateau in 2008 and removal of osteosynthesis material in 2009. TKA with a lateral metal augment and intramedullary stem was performed in 2010...

This study presents the numerical analysis of stem fixation in hip surgery using with/without cement methods since the use of cement is still controversial based on the clinical studies in the literature. Many different factors such as stress shielding, aseptic loosening, material properties of the stem, surgeon experiences etc. play an important role in the failure of the stem fixations. The stem fixation methods, cemented and uncemented, were evaluated in terms of mechanical failure aspects using computerized finite element method...

INTRODUCTION AND HYPOTHESIS: Posthysterectomy vaginal vault prolapse repair is a surgical challenge. Successful surgical management using native tissue can be achieved via the vaginal approach by iliococcygeus fascia fixation. However, although iliococcygeus fascia fixation is technically simple and has a low morbidity, it is not commonly performed. The aim of the video is to provide anatomic views and the surgical steps necessary to achieve successful transvaginal iliococcygeus fascia fixation for vaginal vault prolapse repair...

Introduction Preoperative assessment of vertebral artery (VA) is important to avoid its injury during surgery at craniovertebral junction (CVJ). The main concern is the course of third segment of VA (V3) while performing instrumentation at CVJ, that is, segment of VA from its course through transverse foramen of C2 to its course along the posterior arch of C1. This segment of VA includes its passage through C1 transverse foramen as well. This observational study was done to analyze the course, curvature, and termination of VA in patients with occipital assimilation of atlas at CVJ, a complex congenital anomaly, and compared with the normal course for better understanding especially by young neurosurgeons and spine surgeons...

PURPOSE: Nowadays, in orbital wall reconstruction, maxillofacial surgeons have the possibility to treat patients in modern ways such as with individual implants. Nevertheless, conventional treatment including standard titanium mesh shaped during the surgical procedure is also widely used. The aim of this study was to compare the above methods of orbital wall reconstructions. MATERIALS AND METHODS: In the first group (39 cases), patients were treated by means of computer-aided design/computer-aided manufacturing (CAD/CAM) milled individual implants made of ultra-high-molecular-weight polyethylene, dioxide zirconium and rapid prototyping titanium mesh pre-bent on an ABS model made by a three-dimensional (3D) printer...
