BACKGROUND A new medical device uses high-frequency electrical algorithms to create intermittent vagal blocking (VBLOC therapy). The aim is to assess the effects of vagal blocking on excess weight loss (EWL), safety, dietary intake, and vagal function. METHODS An open-label, 3-center study was conducted in obese subjects (body mass index [BMI] 35-50(More)
BACKGROUND A laparoscopically implantable electrical device that intermittently blocks both vagi near the esophagogastric junction led to significant excess weight loss (EWL) in an initial clinical trial in obese patients. The study objective was to optimize therapy algorithms and determine the EWL achieved with a second-generation device at university(More)
IMPORTANCE Although conventional bariatric surgery results in weight loss, it does so with potential short-term and long-term morbidity. OBJECTIVE To evaluate the effectiveness and safety of intermittent, reversible vagal nerve blockade therapy for obesity treatment. DESIGN, SETTING, AND PARTICIPANTS A randomized, double-blind, sham-controlled clinical(More)
BACKGROUND Intermittent, reversible intraabdominal vagal blockade (VBLOC® Therapy) demonstrated clinically important weight loss in feasibility trials. EMPOWER, a randomized, double-blind, prospective, controlled trial was conducted in USA and Australia. METHODS Five hundred three subjects were enrolled at 15 centers. After informed consent, 294 subjects(More)
BACKGROUND Laparoscopic adjustable gastric banding (LAGB) remains the most popular bariatric procedure performed in Australia and Europe. Gastric band erosion is a significant complication that results in band removal. The aim of this study is to assess the prevalence of band erosion and its subsequent management with a particular focus on rebanding(More)
BACKGROUND Laparoscopic adjustable gastric banding (LAGB) requires surgical access to the gastroesophageal junction, which may be compromised by the enlarged, fatty liver that is frequently encountered in the obese. Liver size appears reduced and surgical access improved following preoperative weight loss with Optifast Very Low Calorie Diet (VLCD). The aim(More)
BACKGROUND An active device that downregulates abdominal vagal signalling has resulted in significant weight loss in feasibility studies. OBJECTIVE To prospectively evaluate the effect of intermittent vagal blocking (VBLOC) on weight loss, glycemic control, and blood pressure (BP) in obese subjects with DM2. METHODS Twenty-eight subjects were implanted(More)
SUMMARY AIM To compare regional lipid deposition and insulin sensitivity after differing weight loss strategies: very low calorie diet (VLCD) and laparoscopic adjustable gastric banding (LAGB). METHOD Thirty-nine obese women underwent anthropometry, proton magnetic resonance (MR) spectroscopy for assessment of liver fat (LFAT) and MR imaging for(More)
BACKGROUND Milan and University of California San Francisco (UCSF) Criteria have been used for selection of patients with hepatocellular carcinoma (HCC) for liver transplantation (LTx). The aims of this study were to analyse the results of LTx for HCC in Australia and New Zealand with emphasis on the effects of discordance between pre-LTx radiological and(More)
BACKGROUND Diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) has been practised widely over the last 20 years, and it has revolutionized the diagnosis and management of biliary and pancreatic conditions. More recently newer techniques (magnetic resonance imaging) for diagnosis and therapy (laparoscopic biliary surgery) have(More)
