BACKGROUND AND STUDY AIMS The Endocuff is a new colonoscopy accessory that has been designed to improve both the adenoma detection rate and endoscope tip control. PATIENTS AND METHODS A total of 50 Endocuff-assisted colonoscopies were analyzed retrospectively with regard to safety, procedural success, and complications. RESULTS The cecal intubation rate(More)
BACKGROUND AND STUDY AIMS Double-balloon enteroscopy (DBE) has been proven effective for deep intubation of the small bowel. However, intubation depth is limited by distention of the small bowel due to air insufflation during the procedure. The present trial investigated whether carbon dioxide (CO (2)) instead of standard air insufflation would improve(More)
BACKGROUND Autologous chondrocyte implantation (ACI) is an accepted surgical treatment in patients with isolated cartilage defects of the knee. Age has been considered as a limiting factor and the technique has not been recommended in patients older than 40 to 50 years. Nevertheless, some more recent studies report satisfying clinical results in middle-aged(More)
INTRODUCTION Since introduction of autologous chondrocyte implantation (ACI), various factors have been described that influence the clinical outcome. The present paper investigates the influence of bone marrow edema at time of treatment on clinical function before and in the early clinical course after ACI. METHODS 67 patients treated with ACI for(More)
BACKGROUND Gonosomal aneuploidies such as Klinefelter syndrome (47,XXY) are the most frequent chromosomal aberration in infertile men. Normally the chromosomal status of patients is detected by karyotyping of up to 20 metaphase spreads of lymphocyte nuclei, whereby low grade mosaicism may be overlooked. To test whether Klinefelter patients with 47,XXY(More)
BACKGROUND AND STUDY AIMS Carbon dioxide (CO2) insufflation has previously been shown to have advantages over air insufflation in terms of procedure-related pain and oral insertion depth during double-balloon enteroscopy. The aim of this prospective study was to evaluate the performance of CO2 vs. air insufflation during single-balloon enteroscopy. (More)
BACKGROUND AND STUDY AIMS Double-balloon enteroscopy (DBE) is the first choice endoscopic technique for small-bowel visualization. However, preparation and handling of the double-balloon enteroscope is complex. Recently, a single-balloon enteroscopy (SBE) system has been introduced as being a simplified, less-complex balloon-assisted enteroscopy system. (More)
BACKGROUND As a non-invasive and readily available diagnostic tool, ultrasound is one of the most important imaging techniques in medicine. Ultrasound is usually trained during residency preferable according to German Society of Ultrasound in Medicine (DEGUM) standards. Our curriculum calls for undergraduate training in ultrasound of medical students in(More)
PURPOSE This study aims to compare double- (DBE) and single-balloon enteroscopy (SBE) in small bowel disorders with respect to procedural performance and clinical impact. METHODS This retrospective analysis at a tertial referral center included 1,052 DBEs and 515 SBEs performed in 904 patients over 7 years. Procedural and patients' characteristics were(More)
AIM To report the largest patient cohort study investigating the diagnostic yield of intraductal ultrasound (IDUS) in indeterminate strictures of the common bile duct. METHODS A patient cohort with bile duct strictures of unknown etiology was examined by IDUS. Sensitivity, specificity and accuracy rates of IDUS were calculated relating to the definite(More)
