Requirement and postoperative outcomes of abdominal panniculectomy alone or in combination with other procedures in a bariatric surgery unit.
2009
Abstract Background A high percentage of patients present with redundant skin folds after bariatric surgery. This study aims to quantify the need for panniculectomy after open bariatric surgery and to analyze the postoperative outcomes. Methods A retrospective cohort study was performed. The patients were divided into 2 groups: group DLP, patients who underwent an abdominal panniculectomy alone and group DLP+, those who underwent panniculectomy in association with another surgical procedure. Results Four hundred forty-six patients underwent open bariatric surgery and 130 patients (29%) subsequently required an abdominal dermolipectomy. Seventy-six percent presented also incisional hernia an…
Use of a collagen/elastin-membrane for the tissue engineering of dermis.
1999
In an experimental model in rats, xenogeneic membranes consisting of processed native collagen and elastin were grafted to serve as a template for the formation of a neo-dermis, while in vitro-cultured autogeneic keratinocytes were applied on top of this to restore an epidermis. The process of tissue reconstruction and the digestion of the grafted membrane components were analysed by histological and immunohistochemical methods as well as electron microscopy. Approximately 3 weeks post grafting the membranes were completely vascularised and colonized by different types of cells. After 6 weeks, the collagenous fibres of the graft were mostly replaced by newly formed collagenous texture, wher…
End Cutaneous Ureterostomy for the Management of Severe Hydronephrosis
2007
Purpose: Although rarely indicated, surgical treatment of severe megaureter can pose a formidable technical challenge, especially in the small infant. We present our experience and outcomes with end cutaneous ureterostomy as a temporizing adjunct to future ureteral reimplantation. Materials and Methods: We performed a retrospective cohort study of patients who underwent end cutaneous ureterostomy between 1993 and 2005. Patient demographics, surgical details and outcomes were recorded. Results: A total of 29 patients (22 males, 7 females) underwent diversion of 34 renal units. Primary megaureter was diagnosed in 15 patients (17 renal units). Secondary megaureter was found in 10 patients (12 …
Non-viral VEGF(165) gene therapy--magnetofection of acoustically active magnetic lipospheres ('magnetobubbles') increases tissue survival in an overs…
2008
Abstract Adenoviral transduction of the VEGF gene in an oversized skin flap increases flap survival and perfusion. In this study, we investigated the potential of magnetofection of magnetic lipospheres containing VEGF165-cDNA on survival and perfusion of ischemic skin flaps and evaluated the method with respect to the significance of applied magnetic field and ultrasound. We prepared perfluoropropane-filled magnetic lipospheres (‘magnetobubbles’) from Tween60-coated magnetic nanoparticles, Metafectene, soybean-oil and cDNA and studied the effect in an oversized random-pattern-flap model in the rats (n= 46). VEGF-cDNA-magnetobubbles were administered under a magnetic field with simultaneousl…
Ten-year Experience with the Supraorbital Subfrontal Approach through an Eyebrow Skin Incision
2005
Abstract OBJECTIVE: More than ever before, the priority in contemporary neurosurgery is to achieve the greatest therapeutic effect while causing the least iatrogenic injury. The evolution of microsurgical techniques with refined instrumentation and illumination and the enormous development of preoperative and intraoperative diagnostic tools enable neurosurgeons to treat different lesions through limited and specific keyhole approaches. METHODS: Based on our surgical experience, the technique of supraorbital subfrontal craniotomy is described in detail in this article. After an eyebrow skin incision is made, a limited supraorbital craniotomy is performed with a width of 15 to 25 mm and a hei…
Transverse Small Skin Incision for Carotid Endarterectomy
2015
The purpose of this report is to determine the feasibility of short transverse skin incision (STI4 cm) for eversion (EEA) and patch (PEA) endarterectomy with or without shunt by comparing it with the outcomes after long transverse skin incision (LTI 4-8 cm).Of 164 elective consecutive patients (71 ± 2.73% symptomatic) operated at one institution over 24 months, 81 were treated with STI, while 83 patients received LTI. The LTI and STI groups did not differ in terms of age, symptoms, or risk factors. EEA or PEA under locoregional (LRA) or general (GA) anesthesia were performed.STI was associated with shorter operation times (75.19 ± 15.33 vs. 94.87 ± 41 and 99.4 ± 27.36 vs. 132.66 ± 51.32, re…
