Filter by:Study objectives: 1. generate local clinical, health-related quality-of-life and health economic data to evaluate the benefits of two types of minimally invasive weight-loss surgery 2. support multi-disciplinary bariatric sites in Germany by providing structured procedure guidelines and training, therefore facilitating procedural adoption, increasing safety and shortening the learning curve for weight-loss surgery.
Despite the relative consensus on the benefits of pre-surgical weight loss, i.e., the reduction of comorbidities associated with surgical act, such as decreased visceral fat, liver volume, hemorrhage perioperative and surgical time, the characteristics of the diet to be employed in this period need to be defined more clearly. As there is no description of comparative studies on diet of normal consistency, using solids and liquids, there are doubts as to the real need for consistency liquid diet in preoperative bariatric surgery. The lack of robust evidence has made nutrition professionals adopt different procedures. There is still a belief that these patients are unable to lose weight in the preoperative period, the ongoing history of previous attempts without success.
Ketamine may improve recovery from bariatric surgery.
Obese people pose specific problems as far as the management of airway during surgery. The study aims to compare efficacy and safety of two LMA devices.
Objective: to assess the effect of gastric bypass on HDL-cholesterol concentration and its Apolipoprotein A4 content at 1 year following bariatric surgery in comparison with a hypocaloric diet. Secondary aim was to measure total cholesterol and triglycerides levels as well as insulin sensitivity after interventions. Summary Background Data: Very few prospective uncontrolled studies have investigated the effects of Roux-en-Y gastric bypass (RYGB) on cardiovascular risk factors. No controlled studies had as primary goal the changes in HDL-cholesterol after gastric bypass. Methods: Forty subjects with a BMI>40 or ≥35 kg/m2 in the presence of diabetes were enrolled. Twenty of them were operated of RYGB while 20 received lifestyle modification suggestions and medical therapy for obesity complications (diabetes, hypertension and hyperlipidemia).
The purpose of this research study is to evaluate whether combining laparoscopic adjustable gastric band (AKA: lap-band surgery, LAGB) and laparoscopic gastric plication (making tucks in the large curve of the stomach with stitches) to lap-band surgery alone will result in a greater loss of excess weight over time. We anticipate that the average percent of excess body weight loss for study subjects will exceed 29% at 12 months.
Abstract: Fatty liver most frequently corresponds to a fat overload of the liver. It is usually classified as alcoholic steatosis or non-alcoholic steatosis. In the case of non alcoholic fatty liver overload, the histological spectrum ranges from simple steatosis to steatohepatitis (NASH) which associates inflammation to steatosis, with a risk of progression to fibrosis and cirrhosis. Obese patients are at particular risk of NASH. Screening of these hepatic lesions is difficult especially as they may exist while the liver tests are normal. The diagnosis of NASH is currently done by liver biopsy, which exposes them in particular to the risk of hemorrhagic complications. Number of subjects required: According to the literature and data collected Louis Mourier in the recent years, the inclusion of 200 patients would examine 20-40 patients with severe histological steatosis and steatohepatitis. All patients will be included in Louis Mourier hospital. Follow-up: one month Search duration: 37 months Duration inclusions: 36 months The total duration of participation for a patient will be one month. Methodology: It is a monocentric, prospective study evaluating the value of noninvasive tests for the diagnosis of hepatic lesions in morbid obese patients. The "open " MRI system allows access to MRI for all obese patients (maximum weight 250 kg). Three of such systems are available in France and liver pathology can be explored only on the system of Louis Mourier. The reference method is liver histology; studied tests are abdominal MRI, Fibroscan / CAP, and serum tests. Examinations required specifically for research Examinations required specifically for the research is abdominal MRI, FibroScan/ CAP and serum tests. Primary endpoint : To validate the use of abdominal MRI, the FibroScan/ CAP and serum tests for finding severe steatosis and / or NASH, specificity, sensitivity, positive and negative predictive values of these tests are calculated. The gold standard is the result of histology on liver biopsy, with a morphometric study of these parameters. ROC curves are used to determine the best compromise between sensitivity and specificity. The secondary endpoints were: Histological lesions of liver fibrosis. Quantification of abdominal fat by MRI (in the form of three variables of interest: quantification of the surface of the visceral fat, of subcutaneous fat and of intrahepatic fat assessed by the percentage loss of signal
The aim of this study is to increase our knowledge about the effect of physical activity in patients who have undergone gastric bypass surgery. The study will provide novel information in two areas. The main objective is to study the effect of physical activity on the weight loss and cardiovascular risk factors. This will be accomplished in a randomized clinical trial in patients, who are eligible for gastric bypass (GB). Patients will be randomized to six month of structured physical activity or standard postoperative counseling. The study will include an exhaustive panel of blood tests related to cardiovascular risk and the most extensive evaluation of structural and functional vascular test done in this patient group so far. In addition the study will provide information of the effect of bariatric surgery per se since both pre- and postoperative investigations are conducted. The study will learn us to what degree it is possible to motivate this group of patients to increased physical activity. All together this will enable us to improve the counseling of the patients undergoing GB.
Morbid obesity is an increasing medical problem in the western countries. It's related to comorbidities as diabetes mellitus, hypertension, OSAS, arthrosis and hypercholesterolemia. The Roux-en-Y Gastric Bypass (RYGB) is an effective surgical therapy for morbidly obese patients. A part of these patients will have disappointing results, and have weight regain on the long term. Some studies show more weight reduction by increasing the biliopancreatic limb in patients with morbid obesity. The objective of this study is to investigate the effect of variations in the length of biliopancreatic limb on weight reduction in morbidly obese patients undergoing RYGB-surgery. We hypothesize that longer biliopancreatic limb results in more weight reduction. The study design is a prospective, randomized control trial. The patients will be randomized in 2 groups: a standard RYGB (short biliopancreatic limb) and long biliopancreatic limb RYGB.
Single-Anastomosis Duodeno-Ileal bypass with a 250 cm common/alimentary loop is a modification of standard duodenal switch in which a Roux-en-Y duodeno-ileal anastomosis is performed at 250 cm from the cecum and a 60 cm to 100 cm common channel is build up. Hypothesis of the study is that Single-Anastomosis Duodeno-Ileal bypass behaves at least equally to standard duodenal switch as a second step after sleeve gastrectomy in the super-morbid patient. Secondary aims are to demonstrate that single-anastomosis duodeno-ileal bypass is simpler to perform, quicker and has less postoperative short, mid and long-term complications.
