Active clinical trials for "Obesity, Morbid"

To investigate if laparoscopic Transversus Abdominis Plane (TAP) block using plain bupivacaine is equivalent to using liposomal bupivacaine in patients undergoing metabolic and bariatric surgery. The study will see if the plain bupivacaine group will be equivalent in terms of length of stay, Morphine Milligram Equivalents, Pain scores and patient satisfaction, but cost less.

The present randomized clinical trial aims to prove the safety and efficacy of an interactive mobile application (Care4Today®) to obtain sufficient weight loss and empower patients with morbid obesity before being submitted to a gastric by-pass.

The goal of this randomized controlled trial is to compare laparoscopic guided peri-wound Transversus Abdominis Plane Block and bupivacaine versus local wound infiltration effect on reducing post-op opioid use in Laparoscopic Sleeve gastrectomy. The main questions it aims to answer are: • Can laparoscopic guided peri-wound Transversus Abdominis Plane Block reduced post operative morphine usage when comparing with local wound port site infiltration. Participants will be randomize into 2 group peri-wound Transversus Abdominis Plane Block local wound port site infiltration

in this study the investigators will test anew technique to mange patients with morbid obesity and GERD by doing sleeve gastrectomy plus cruroplasty and omental rape around the gastroesophageal junction

Morbid or severe obesity is a chronic pathology of multifactorial etiology that affects 4.3% of the French population. In these patients, eating disorders are frequent and must be managed as they are considered risk factors with poorer weight prognosis and lower quality of life. Some authors have proposed that the concept of food addiction (i.e., the existence of an addiction to certain foods rich in sugar, fat and/or salt) may make it possible to identify, among obese patients, a subgroup of patients that is more homogeneous in terms of diagnosis and prognosis. Food addiction is common in obese patients and is associated with higher levels of depression, anxiety, impulsivity, emotional eating and poorer quality of life. Nevertheless, we do not know the impact of managing this addiction on the future of these patients (food addiction, weight, comorbidities, quality of life). Telephone-based cognitive behavioral therapy intervention (Tele-CBT) is a treatment of choice for addictions, but there are inequalities in access to this treatment (distance between home and hospital, limited local resources of caregivers, constraints in patient availability) which require the therapeutic framework to be adapted to these constraints. A short Tele-CBT program has demonstrated its effectiveness in reducing bulimic hyperphagia in these patients (Cassin et al. 2016), but its effectiveness on food addiction, Body Mass Index and the evolution of metabolic complications related to obesity is still unknown. The evaluation of this program was limited to 6 weeks (American study), and we do not know if these results can also be extrapolated to France. The main hypothesis of this study is that in patients suffering from severe or morbid obesity and with food addiction, the performance of tele-CBT (intervention group: 12 sessions for 18 weeks) will be accompanied by a significant medium-term decrease in the prevalence of food addiction compared to usual management (control group).

Evaluation of the functional changes in the stomach and esophagus of patients undergoing One Anastomosis Gastric Bypass (OAGB)

The objective of the study, which is framed within European Union's H2020 project titled SOCRATES, is to assess the clinical efficacy of a Virtual Reality (VR) embodiment tool for treating obesity and to compare it to usual care, through a Randomized Controlled Trial

Morbid obesity is the first non-traumatic cause of death in the western population and it is also progressively beginning to affect the developing countries. Bariatric surgery provides better results than pharmacological treatments and lifestyle changes, granting a better control of comorbidities. Duodenal switch (DS) has proben to be the most effective surgical treatment for grade IV morbid obesity and its comorbidities. However, it is not widely used due to its technical complexity and the risk of long-term complications. Single Anastomosis Duodenum-Ileal bypass with Sleeve gastrectomy (SADI-S) was concieved in 2007 as a one-anastomosis simplification of DS, intended to diminish the surgical time and postoperative risks. Recently, another simplified hypo-absorptive technique has started to be widely used: the one anastomosis gastric bypass (OAGBP), also called mini-gastric gypass. It consists of a gastric pouch associated with a gastro-jejunal anastomosis in omega (Billroth II). Despite the potential advantages of these emerging surgical techniques (SADI-S and OAGBP), there is no solid evidence on its efficacy for the treatment of grade IV obesity in comparison with DS. Besides, there is also there is a lack of studies reporting on prospective acid and bile reflux after omega digestive reconstructions, suche as "Billroth II-like" (SADI-S) and "Billroth II" (OAGBP). Bile reflux is potentially premalignant condition. This prospective randomized study aims to compare conventional DS with SADI-S and OAGBP. We include all morbidly obese patients with BMI ≥ 50 kg/m2 aged 18 years or more. Exclusion criteria are patients who do not fulfill our preoperative bariatric assessment for surgery and those with contraindications for hypo absorptive or mixed surgery. The main objective of the study is to compare the percentage of excess weight lost at 2 and 5 years after the three different surgical procedures. As a secondary objective, gastroesophageal reflux (GERD) will be compared before and 2 years after surgery, based on GERD symptoms test, gastroscopy and a esophageal pH-impedanciometry in selected patients. Other secondary objectives are comparison of short-term complications, metabolic comorbidities, depositional habit, quality of life and metabolic and nutritional deficiencies at two years of surgery.

This is a 12-month, single center, three-arm parallel design, double-blind, randomized clinical trial, to compare the effects of supplemental dietary fiber and metformin (MET) alone and in combination over 12 months on glucose metabolism (insulin resistance [IR]), inflammation and BMI in adolescents with obesity and IR, and to assess the relationship between therapeutic intervention(s) and changes in gut microbiome composition and function. Since MET and FIBER have been shown to reduce weight and increase insulin sensitivity through distinct but overlapping mechanisms of action, our central hypothesis is that the combination of FIBER + MET will have a synergistic effect and be more effective than FIBER or MET alone in improving metabolic function (IR) and reducing BMI and inflammation in adolescents with obesity, IR and family history (FM) of T2DM. .

Obesity is a major public health problem worldwide. Bariatric surgery has proved to be the most effective treatment of morbid obesity in terms of weight reduction and remission of co-morbid conditions during long-term follow-up. Sleeve Gastrectomy (SG) has become the most performed intervention either worldwide or in France, where SG represents more than 60% of bariatric interventions and 114,817 patients operated between 2013 and 2016. Maximum Excess weight loss (%EWL) after SG is obtained at one-year post surgery. Then it has been largely reported in the literature that patients could present mild, moderate or important (notably in the super obese patients) weight regain associated with comorbidity relapse motivating redo surgery. Like in revisional surgery, operating super-obese patient (BMI ≥50 kg/m2) is a challenge. It has been shown that achieving significant weight loss was more difficult in patients with a BMI ≥ 50 compared to lower BMIs.
