Active clinical trials for "Obesity, Morbid"

This prospective study will assess the value of different supplements to orpofol bases anesthesia in morbidly obes e patients scheduled for balloon insertion. Two common drugs will be added to propofol bases anesthesia;Ketamine or fentanyl. Effect on prpofol consumption, post-procedure recovery profile, and patient satisfaction will be the study objectives.

The purpose of this study is to assess the safety profile of bariatric embolizations and confirm published reports of sustained post-procedural weight loss, and pathologically assess post-procedural metabolic effects.

This research program aims to comprehensively investigate the clinical, physiological, metabolic, and molecular effects of reducing sedentary behavior in post-bariatric patients. To this aim, we will conduct a crossover trial and a randomized controlled trial. The crossover trial aims to unravel potential mechanisms underlying the metabolic, physiological and molecular effects of breaking up sedentary time with light-intensity physical activity versus carrying out the minimum amount of daily exercise at once and then remaining sedentary versus simply remaining sedentary throughout all sessions, in a well-controlled laboratorial condition. The 4-month parallel-group randomized controlled trials aim to investigate the feasibility and efficacy of a newly developed personalized intervention focused on replacing sedentary time with light- (or very light-) intensity physical activity in these patients. A multitude of gold-standard techniques will be applied to evaluate the effects of the intervention on several outcomes, including sedentary time (primary outcome), physical activity levels, clinical parameters specific to each condition, cardiometabolic risk factors, immune function, and health-related quality of life.

Background While several articles have reported about the effects of laparoscopic sleeve gastrectomy (LSG) on the lower esophageal sphincter (LES), to date, just one paper has discussed this issue with regard the Mini/One anastomosis gastric bypass (MGB/OAGB). This is expected to be the first randomized trial exploring and comparing these two interventions. Setting "Federico II" University Hospital, Naples - ITALY. Methods Fifty morbid obese patients are going to be studied. All patients presenting with a normal preoperative LES function will be randomly assigned to undergo LSG (arm 1 - 25 pts) or MGB (arm 2 - 25 pts). Patients undergo clinical assessment for reflux symptoms, and esophago-gastro-duodenoscopy (EGDS) plus high-resolution impedance manometry (HRiM) and 24-hour pH-impedance monitoring (MII-pH) before, two months and 1 year after both LSG or MGB/OAGB. Objective Endpoint 1: Does this surgery affect the LES area function in both arm 1 or arm 2 patients determining a possible increase in gastroesophageal acid or non acid reflux? Endpoint 2: Does one between the two procedures outperform the other one in terms of eventual LES area modifications? Endpoint 3: In the case of a good performance of LSG or MGB/OAGB or both the procedures, is this to be primarily related to surgery per se or to weight loss?

Evaluate the safety and efficacy of an early discharge protocol (23 hours, overnight stay) after scheduled sleeve gastrectomy.

The present study aims to explore the impact of combining laparoscopic greater curvature plication with a single gastro-ileal anastomosis in the same manner of single anastomosis sleeve ileal bypass on weight loss and postoperative complications. The objective of this combined procedure is to reduce the high intraluminal pressure that results after laparoscopic greater curvature plication owing to reduced intraluminal space which can lead to suture line leakage, vomiting, and gastroesophageal reflux disease. Another objective is to add a malabsorptive element to the restrictive effect of laparoscopic greater curvature plication and to induce early satiety in patients by distention of the distal bowel with nutrients immediately after meals, similar to the way that single anastomosis sleeve ileal bypass works.

The aims of the study are to perform psychological intervention using EMDR Therapy (Eye Movement Desensitization and Reprocessing Therapy) in the preoperative period, evaluate the personality of each patient through the PFB test (Personality Factor Battery Test) at different times, compare the results obtained in the PFB test at different times of application and verify the existence of changes in the five major Personality Factors: Neuroticism, Extroversion, Socialization, Realization and Openness.

The purpose of this study is to find out more about the safety and effectiveness of the Laparoscopic Greater Curvature Plication (LGCP) procedure in patients with obesity and related problems such as diabetes, hypertension, high cholesterol, mild obstructive sleep apnea, and joint problems. LGCP is a less invasive weight loss surgery procedure than some of the other weight loss surgeries and it is possible that there are fewer risks with this procedure than with the other weight loss surgeries. LGCP is considered an experimental procedure and this study is being done to look at the long-term outcomes.

Surgical bypassing of a longer section of the small bowel (when doing a gastric bypass operation) gives better results on body weight in the superobese. We do not yet know whether it is beneficial to exclude more of the proximal small bowel or more of the distal. Side effects of bypassing can also be different. Study aims at clarifying possible differences in effects and side-effects of these two surgical-technical variations.

Weight loss achieved by dieting induces multiple changes. These changes include a decrease in metabolic rate (the rate in which the body burns its calories), an increase in appetite and other physiological and hormonal changes that may be the cause of failure in dieting. Many of these parameters that have never been evaluated when weight is lost after gastric bypass surgery will be tested in this study.
