Filter by:The frequency of super-super obese who need immediate weight loss surgery is risen continuously. For those patients a prior-to-surgery conditioning therapy is mandatory to gain technical and physical operability. The exclusively well-established preliminary therapy so far was the intragastric balloon, which takes 7 months of treatment time. Due to life-threatening conditions of giant obese patients, who have been admitted to hospital, the investigators were forced to develop a more prompt acting conditioning therapy to bring those individuals in a short run to an improved and "fit-for-surgery" state. In such an impasse the investigators combine Liraglutide with its well-known weight-loss effect with a leucine-based amino acid infusion that is generally used for patients with liver insufficiency, in expectance of an additional weight loss and liver reduction effect.
Rapid onset Obesity, Hypoventilation, Hypothalamic dysfunction and Autonomic Dysregulation (ROHHAD) is a syndrome named in 2007. The hallmark of the syndrome is the rapid onset obesity and dysregulation of central ventilation. There is little information about the metabolic changes that lead to the rapid onset obesity in these children. The investigators would like to study the metabolic phenotype of these children to understand the disturbances in energy balance that lead to the rapid onset obesity.
The risk of complication associated with airway in obese patient is important. The result of pre-oxygenation gives the clinician a prolonged non-hypoxic apnea time. The relation between FRC and non-hypoxic apnea time has been correlated. However, the best condition to accomplish the pre-oxygenation in morbidly obese patient has yet to be described in the medical literature. A study previously done in our hospital (EPO2-PV) compared the effect of different positions and ventilation modes on the FRC in the laboratory. A significant difference has been established on the FRC between the inverse Trendelenburg position with positive pressure ventilation and the head up ("beach-chair") position without positive pressure. The current study, EPO2-A is designed to compared the two positions and ventilation modes during the induction of general anesthesia on morbidly obese and correlate the difference in FRC to difference in apnea time.
The aim of this study is to determine the correlation of neck circumference with difficult mask ventilation and laryngoscopy in morbidly obese patients.
Pediatric obesity has become a critical health problem worldwide, increasing the premature onset of obesity-related morbidities. This phenomenon has induce an increase in the incidence of serious health complications starting in childhood and adolescence. Lifestyle interventions, including diet and regular physical activity, are the cornerstone of current medical management. Unfortunately, these interventions are often ineffective in providing a meaningful and long-lasting weight loss necessary to change health outcomes. It has been demonstrated that an early intervention in obesity in children and adolescents, inducing weight loss by performing bariatric surgery in carefully selected patients, can dramatically reduce the risk of adulthood obesity and obesity-related diseases, including non-alcoholic fatty liver disease (NAFLD). Recent evidence suggest that bariatric surgery can improve metabolic complications and liver involvement in patients affected by morbid obesity.
A Roux-en-Y Gastric Bypass (RYGB) is on the long term not always successful in every patient because weight regain can occur. An intervention to prevent weight regain in the future is to place a silicone band (non-adjustable) around the pouch of the RYGB (Banded-RYGB: BRYGB) which increases weight loss and decreases weight regain on the longer term. The question is whether primary application of a banded bypass gives a greater weight loss and / or prevent weight regain in the future versus a standard RYGB.
This randomized double blind clinical trial focuses on patients with Body Masse Index ≥ 40 kg/m2, undergoing scheduled surgery. Neuromuscular transmission monitoring at the adductor is performed using. Anaesthesia is induced with anaesthesic and maintained with curare. At the end of the procedure, patients with profound neuromuscular blockade receive either 1 mg/kg, 2 mg/kg or 4 mg/kg Sugammadex based on ideal body weight. A complete reversal failure is defined by a Train Of Four ratio < 0.9 within 10 min after administration of Sugammadex or if recurarization occurs within 15 min after complete reversal success.
The study evaluates the gastric emptying by scintigraphy in patients that had bariatric surgery (RYGB of gastric sleeve) comparing patients with successful and unsuccessful weight loss and in patients before and after the placement of a duodenal-jejunal bypass liner. Additional, after bariatric surgery gut hormones that influence the gastric emptying rate are determined.
Comparison of harmonic scalpel and ligasure devices in laparoscopic morbid obesity surgery especially in gastric bypass surgery patients.
The purpose of this study is to evaluate pharmacokinetics of paracetamol, amoxicillin and talinolol in morbid adipose subjects before as well as shortly after and about one year after proximal Roux-en-Y Gastric Bypass (RYGB) and to measure messenger ribonucleic acid (mRNA) expression and protein content of duodenal and/or jejunal drug metabolizing enzymes (eg. cytochrome P450 isoenzyme 3A4 (CYP3A4), uridine diphosphoglucuronosyltransferase (UGTs)) and drug transport proteins (e.g. P-glycoprotein, MRP2, OATPB, PEPT) before and during the operation and about one year after proximal RYGB.
