Active clinical trials for "Obesity, Morbid"

This study has two phases: In phase 1 of the study (8 weeks),the effect of two different low calorie diets on manifestations of PCOS, including risk factors for the metabolic syndrome and cardiovascular risk profile will be compared. In phase 2 the long term effect (next 44 weeks) on sustained weight-loss and the above mentioned parameters will be compared and evaluated.

The investigators aim to determine the clinical and metabolic effects of sleeve gastrectomy with or without omentectomy in the treatment of morbid obesity. The investigators hypothesize that the endocrine suppression of ghrelin (appetite hormone)and resistin (insulin antagonist) provided by sleeve gastrectomy and omentectomy (omentum or intra-abdominal fat removal) will provide clinical and metabolic benefits for morbidly obese patients.

This two site study will evaluate the safety and effectiveness of laparoscopic truncal vagotomy for the treatment of obesity with baseline study and 18 month post op follow up.

This study aims to compare the efficacy of dexmedetomidine versus fentanyl during general anesthesia for patients with morbid obesity undergoing laparoscopic sleeve gastrectomy.

Compare the effects of two different doses of dexmedetomidine infusion on oxygenation as a primary outcome and on lung mechanics, quality of recovery and perioperative analgesia as secondary outcomes in morbidly obese patients with restrictive lung disease undergoing abdominal surgery.

Stapler-less laparoscopic sleeve gastrectomy (LSG) is emerging as a new potential affordable cost-effective alternative procedure. However, no pre-clinical data are currently available on human tissue. We aimed to evaluate whether traditionally suturing without the use of surgical stapling may produces a comparable bursting pressure on human gastric tissue.

Weight regain after Laparoscopic Sleeve Gastrectomy (LSG) is nowadays a growing concern. Sleeve dilatation and loss of food restriction is considered the main mechanism. The placement of a silicon ring around the gastric tube seems to give benefits in the short-term. The Investigators evaluate the efficacy of banded sleeve gastrectomy compared to standard sleeve in the mid-term. Fifty patients were randomized between LSG and Laparoscopic Banded Sleeve Gastrectomy (LBSG), and they underwent a mean follow-up of 4 years. Patients' management was exactly the same, apart from the band placement. After surgery differences in weight loss, operative time, complication rate and mortality were analyzed.

The study aims to: 1) investigate the effects of cognitive training (CT) and combined CT and transcranial direct current stimulation (tDCS) on food intake and 2) to further understand its neuropsychological and neurophysiological basis (i.e. EEG) as well as its impact in endocannabinoids (EC) in a sample of morbidly obese patients seeking for a gastric bypass surgery

the idea is to use an omental flap or round ligament as a natural band in stead of synesthetic band in bariatric procedures, mainly gastric sleeve

This parallel, double-blind, randomised controlled trial aims to assess the effect of a polyphenol-rich dietary supplement on obesity parameters, in combination with a hypocaloric diet, for adults with morbid obesity, bariatric surgery candidates. Participants (n=40) will be randomly assigned to intervention group (IG) or control group (CG). Together with a regular hypocaloric diet (1,200 kcal/d), the IG will be given the supplement and the CG will be given a placebo. Both groups will take three capsules a day (400 mg per capsule, a total of 1,200 mg), distributed in three daily intakes (with meals). After 12 weeks and 3 visits (baseline visit, week 6 and week 12), pre and post intervention data and intervention versus placebo data will be analysed. Anthropometric and health parameters, dietary habits, lifestyle characteristics and physical activity will be assessed, and blood and urine samples will be collected in all three visits. Faecal samples will be collected at baseline and visit 3. Results will provide evidence on the effects of a combination of polyphenols on several well-established obesity parameters and will unravel possible underlying mechanisms by metabolomic analyses and microbiota diversity.
