Active clinical trials for "Obesity, Morbid"

The surgeries that involve treatment of morbid obesity, i.e. bypass procedure and sleeve gastrectomy, are collectively covered under the term 'bariatric surgery'. The frequency of bariatric surgery has been increasing worldwide for patients with medically complicated obesity who have difficulty losing weight by other methods The growth of bariatric surgery is accompanied with development of anesthetic techniques to maintain patient safety and improve outcome. Treatment with narcotics in obese patients has dual effect. Increased use of narcotics are associated with multiple complications including Postoperative Nausea and Vomiting (PONV) , respiratory depression and elevated risk of Obstructive Sleep Apnea (OSA) complications . On the other hand, the reduction in opioid use may result in acute post-operative pain that may limit post-surgery rehabilitation. Therefore, we need to minimize opioid use and employ some other drugs which, besides having analgesia, has an opioid-sparing effect also. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has analgesic properties in sub-anesthetic doses. When used in low dose (0.3 to 0.5 mg/kg) by ideal body weight, it is an analgesic, anti-hyperalgesic, and prevents development of opioid tolerance. Dexmedetomidine is selective α2-Adrenoceptor agonist that has been used as an adjuvant to anesthetic agents in perioperative period for several adventitious profile as well as tolerated side effects . While dexmedetomidine is emerging as a beneficial adjunct to the analgesic regimen in the perioperative period, its utilization is not routinely widespread .

MAIN OBJECTIVE To compare the effects of the placement of an adjustable gastric band with "conventional" treatment of obesity. SECONDARY OBJECTIVES Compare the effects of the placement of a gastric band with "conventional" treatment of obesity on quality of life, body composition and parameters of the metabolic syndrome. Identify predictors of "good answer to the ring" to determine the best future indications. Study of the gastric tolerance. INCLUSION CRITERIA Adolescents 12 to 16 years and with BMI and weight gain according to sex and age is greater than IMCZ-score > 4 DP> 8 kg Obesity "common" non-syndromic. Medical decision of surgical placement of laparoscopic gastric banding. Adolescent and family who understand and accept the need for medical and surgical follow long term. Adolescent and family who fully understood the oral and written information explaining the study and the need for prolonged follow-up. Obtention of oral and written consent of the adolescent and the parents. Parents and adolescents affiliated with the social security system. NONINCLUSION CRITERIA Intellectual Deficit. psychiatrics contraindication of surgical placement of laparoscopic gastric banding. Obesity with severe binge eating. Pregnancy or wishes of pregnancy in the following year. Non accession adolescent and / or family in the process of medical care before inclusion. Predictable post surgical monitoring difficulties. Suspicion of physical abuse, verbal or negligence / deficiency in care of the family. Participation in a clinical study evaluating a treatment during the 2 years of the study. EXCLUSION CRITERIA Anesthetic contre indication for placement of a gastric laparoscopic. IMC> 50 kg/m2 the day of inclusion. STRATEGIES / PROCEDURES During a routine visit, the study will be presented to the patient and his family. Patients will then be enrolled and randomized. Patients in group A (surgery group) will follow the usual multidisciplinary bariatric surgery in adolescents. Patients in group B start conventional monitoring dietary medical and physical. For both groups follow-up visits will occur every 3 months for 2 years.

The study is primarily to evaluate the safety and efficacy of the LigaSure Advance™ Pistol Grip and LigaSure™ Blunt Tip using the Force Triad™ Energy Platform during Roux-en-Y and gastric reduction procedures (sleeve gastrectomy or placation), respectively. Also, Economic value of using LigaSure in gastric surgeries will be appraised. In this prospective case series, 60 patients previously scheduled to undergo a Roux-en-Y or gastric reduction procedure (sleeve gastrectomy or placation) will have hemostasis controlled with LigaSure Advance ™ Pistol Grip or LigaSure™ Blunt Tip, respectively. All subjects undergoing Roux-en-Y or gastric reduction procedures (sleeve gastrectomy or placation) procedure at Durham Regional Hospital will be recruited. Data Analysis will be performed using the data collected in the software program titled MetaBar at Duke University Medical Center. Categorical variables will be summarized as proportions for each category; continuous measures will be summarized by mean and standard deviation or median and range as appropriated for the data distribution. Procedure-related risks are those typically associated with gastric procedures and general anesthesia including intra-operative bleeding, infection, and injury to surrounding organs and structures. Device related risks include those normally associated with the use of electrosurgery including intra-operative bleeding, unintended tissue burns, electrical shock, and electrical stimulation of muscles and nerves.

Morbid Obesity (MO) is considered the most important epidemic in the developed world in the twenty-first century. After initial assessment of morbidly obese patients and the exclusion of potentially correctable causes, management involves a combination of dietary changes, cognitive therapy, physical activity, psychological support and pharmacological treatment. However, any combination of these factors has proven long-term effectiveness in achieving significant and sustained reduction of excess weight. Currently, surgery is the only treatment capable of achieving this goal, interacting also with significant improvement in quality of life and overall long-term mortality. In recent years, several authors have reported excellent short-term results with performing sleeve gastrectomy, but whether some aspects regarding the variability of gastric tubulization design could influence the results obtained in relation to weight loss and functional changes and gastric hormones. The main objective of this study is to assess the size of the gastric tubulization (based probe calibration and the distance from the pylorus to which initiate gastric section) that can provide a better clinical outcome (such as excess weight loss) in patients undergoing surgery for morbid obesity. Secondary objectives were to assess the morphological changes, physiological and hormonal obtained according to the size of the gastric tubulization and its effect on weight loss patients.

Rationale: In the Western world overweight and obesity is an increasing problem both in adults and in children. In youth, it is associated with early death and a number of co-morbidities including metabolic and endocrine changes, increased inflammatory status, cardiovascular abnormalities, nonalcoholic fatty liver disease, and impaired quality of life. The standard treatment for morbid obesity in children is by combined life style interventions. However, the medium and long term effects of dietetic interventions, behaviour therapy and medication is relatively poor. In adults bariatric surgery shows good results with up to 30% weight reduction in 3 years. The preliminary results in youth are similar, but surgery in this age group is relatively uncommon. In the Netherlands surgery in this age group is only allowed in clinical trials, until the benefits and risks have been established. (National Health Authorities) Objective: To determine if surgery gives a superior weight and body mass index (BMI) reduction than combined life style interventions in adolescents with morbid obesity and to assess its effect on obesity associated co-morbidity. Study design: Prospective randomised interventional study. Study population: Morbidly obese children, aged 14 - 16 years, with sex and age adjusted BMI >40 kg/m2 or >35 kg/m2 with co-morbidity. Intervention: Bariatric surgery by laparoscopic adjustable gastric band (LAGB) or combined life style interventions Main study parameters/endpoints: Primary endpoints: weight loss, loss of excess weight, loss of excess BMI. Secondary endpoints: Body composition, pubertal development, metabolic and endocrine changes, inflammatory status, cardiovascular abnormalities, non-alcoholic steatohepatitis, brain development, quality of life, and behaviour changes. The potential complications of surgery are monitored.

The purpose of this study is to determine whether suppressing acid production by administration of daily proton pump inhibitors in the early post-operative period will reduce the gastrojejunal anastomosis stricture rate in patients undergoing laparoscopic gastric bypass surgery for morbid obesity.

Obesity has been a global epidemic. Currently, bariatric surgery has been recognized as the only successful treatment for morbid obesity. Laparoscopic gastric bypass (LGB) is the leading bariatric surgery worldwide including Taiwan, it's resulted in significant weight loss and resolution of metabolic co-morbidities in morbidly obese patients . However, annoyed Gastro-Intestinal (GI) symptoms are a common complaint after gastric bypass like foul smell flatus, oil flatus and over flatus. The aim of this study was to determine whether probiotics would improve annoyed GI symptoms after gastric bypass. Probiotics are live microorganisms (in most cases, bacteria) that are similar to beneficial microorganisms found in the human gut. They are also called "friendly bacteria" or "good bacteria." Probiotics are available to consumers mainly in the form of dietary supplements and foods.

Thread-embedding Therapy has been used for treating Obesity in recent years. This research is aimed to observe the clinical effect of thread-embedding therapy in treating Simple Obesity. One hundred patients is planned to be enrolled in the research and receive a thread-embedding therapy. The level of BMI, serum triglyceride, cholesterol and fasting blood glucose will be adopted for evaluation before and after therapy.

This study aims to explore the effectiveness of a group psychotherapy intervention using Compassion-Focused Therapy (CFT) in adults with severe obesity. In particular, it aims to evaluate the principle that CFT can be used to reduce levels of shame and self-criticism in adults with severe obesity OBJECTIVES: The objective of the current study is to assess and compare a CFT group intervention to Treatment as Usual (TAU) with regard to psychological functioning, specifically self-compassion, shame, self-criticism, emotional eating and mood.

Laparoscopic Sleeve Gastrectomy (LSG), Also known as longitudinal or vertical gastrectomy. LSG was initially considered a first-stage operation in high-risk patients before bilio-pancreatic diversion or Roux-en-Y gastric bypass surgery. However, LSG was subsequently found to be effective as a single procedure for treatment of morbid obesity.LSG functions mainly as a restrictive procedure in which about 75 % of the stomach is removed leaving a narrow gastric tube or sleeve. So, it limits the amount of food that can be eaten at one time via inducing early satiety after eating a small amount of food due to early distension of the fashioned gastric sleeve giving a sense of satiety, consequently losing excess body weight by time.Sleeve gastrectomy may also cause a decrease in appetite by reducing the amount of Ghrelin (hunger hormone) produced by the stomach.
