3516 Background: CAO/ARO/AIO-94 was published in 2004 with a median follow-up of 46 months (Sauer et al., N Engl J Med 2004). This trial established preoperative CRT as standard treatment for rectal cancer based on an improved local control rate at 5 years, however, no survival benefit could be shown. We here report results with a median follow-up of 134(More)
BACKGROUND Hypercapnic respiratory failure in patients with COPD frequently requires mechanical ventilatory support. Extracorporeal CO2 removal (ECCO2R) techniques have not been systematically evaluated in these patients. METHODS This is a pilot study of a novel ECCO2R device that utilizes a single venous catheter with high CO2 removal rates at low blood(More)
BACKGROUND The purpose of this study was to review surgical experience with gastrointestinal stromal tumours (GISTs) at a single tertiary university hospital, and to identify morphological and genetic prognostic markers of tumour progression. METHODS Forty-eight GISTs from 39 patients were reviewed retrospectively. The prognostic significance of DNA copy(More)
Central airway obstruction is a problem facing all medical and surgical subspecialists caring for patients with chest diseases. The incidence of this disorder appears to be rising because of the epidemic of lung cancer; however, benign causes of central airway obstruction are being seen more frequently as well. The morbidity is significant and if left(More)
STUDY OBJECTIVES To characterize the feasibility, accuracy, and safety of the superDimension/Bronchus system (SDBS) [superDimension, Ltd; Hertzliya, Israel] in navigating to previously unreachable peripheral lung lesions and obtaining biopsy specimens. DESIGN Open-label, prospective, controlled clinical study. SETTING Pulmonary institute of a(More)
INTRODUCTION Incisional hernia surgery in Germany is changing from conventional techniques to mesh implantation. The relevance of different factors such as surgical technique, mesh material, and patient-related parameters concerning the outcome following mesh repair is still under debate. METHODS In a comparative retrospective study of 432 incisional(More)
Human prolactin (HPr), luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, 5 alpha-dihydrotestosterone (DHT), oestrone and oestradiol are measured by radioimmunoassay (RIA) and bilogical prolactin activity additionally by pigeon crop sac assay in plasma of patients with prostatic carcinoma and two control groups. Pigeon crop sac(More)
Transbronchial biopsy (TBBX) for peripheral lung lesions is usually performed with the help of fluoroscopy, but the yield varies widely. This feasibility study aimed to assess the ability of endobronchial ultrasound (EBUS) to provide imaging guidance for TBBX. In a prospective study, 50 consecutive patients referred for TBBX for peripheral lesions underwent(More)
PURPOSE The purpose of this work was to study the diagnostic value of CT and MRI in children with sensorineural hearing loss and to analyze anatomic abnormalities of the inner ear and the vestibulocochlear nerve in this patient group. METHOD We evaluated 42 inner ears in 21 children with congenital deafness who had congenital inner ear malformations and(More)
STUDY OBJECTIVES Conventional transbronchial needle aspiration (TBNA) is a valuable procedure but remains underutilized. Recently, imaging guidance such as CT fluoroscopy has created considerable interest. As CT fluoroscopy is cumbersome and exposes patients and staff to radiation, we have examined the feasibility of endobronchial ultrasound (EBUS) in(More)
