Active clinical trials for "Obesity, Morbid"

The study investigates if applying a special ventilatory strategy during anesthesia for laparoscopic gastric by pass, produces less atelectasis and better oxygenation in spite of using 100 % oxygen during pre oxygenation and induction of anesthesia. The study investigates oxygenation with blood gas samples but also with a new method that might give more information without the use of blood gas samples. Primary: Oxygenation in patients with morbid obesity improves if preoxygenation, induction and maintenance of anesthesia is performed with either a continuous positive airway pressure (CPAP) or a positive end expiratory pressure (PEEP), respectively, of 10 cm H2O, in comparison to a technique without CPAP but with a PEEP of 10 cm H2O. Secondary: The improved oxygenation during anesthesia can be prolonged inte the postoperative period if emergence from anesthesia is performed without high levels of oxygen.

Adequate postoperative analgesia can facilitate recovery following gastric bypass surgery for morbid obesity. The efficacy and safety of intravenous patient - controlled analgesia has been studied, but up to date no data are available concerning the use of thoracic epidural patient-controlled analgesia regarding the use of levobupivacaine combined with morphine in morbidly obese patients. The investigators' aim in this prospective, randomized, double-blinded study was to compare the analgesic effectiveness, the dose requirements and side effects of thoracic epidural patient controlled analgesia 0.1% and 0.2% levobupivacaine combined with a continuous epidural administration of morphine, with or without a loading dose, after open gastric bypass for morbid obesity.

Bariatric surgery is the most effective treatment for morbid obesity. Roux-en-Y gastric bypass (RYGB) is a bariatric procedure with known safety and effectiveness. Laparoscopic sleeve gastrectomy (LSG) is a newer procedure gaining popularity. The aim of the study is to compare outcomes of these two surgical methods in terms of weight loss, improvement of common comorbidities of obesity and influence on metabolic and hormonal status.

The purpose of this study is to determine if residual weakness after weight loss surgery leads to an increased risk of respiratory complications in the postoperative period.

The aim of the present study was to evaluate the additional effect of sudden visceral fat reduction by omentectomy on Metabolic Syndrome, acute phase reactants and inflammatory mediators in patients with morbid obesity undergoing Laparoscopic Roux-en-Y Gastric Bypass.

The purpose of this research study is to evaluate the drug gabapentin (Neurontin®) for its ability to reduce postoperative pain, the need for morphine-like pain medication, and the severity and frequency of postoperative nausea and vomiting in laparoscopic gastric bypass surgery patients.

The purpose of this study is to test the effect of an implanted device that stimulates the stomach on weight loss in patients suffering from obesity and type 2 diabetes.

To investigate the effect of weight loss by gastric balloon insertion on parameters of obstructive sleep apnea.

The laparoscopic sleeve-gastrectomy (SG) compared to laparoscopic proximal Roux-Y-gastric bypass (PGB) is as successful in the treatment of morbid obesity in the majority of patients. In case of insufficient weight loss malabsorption can to be added by performing laparoscopic bilious-pancreatic diversion duodenal switch (BPD). The resection of the gastric fundus (LG) leads to changes in gastrointestinal hormones that are possibly different to bypassing the fundus (PGB).

Several barriers to exercise are present that need to be addressed. Morbidly obese individuals experience more skin friction, urinary stress incontinence, knee pain, low back pain, and hip arthritis than the lean population, which may significantly impair their ability to adhere to an exercise regimen (6). Obesity and overweight also contribute to greater perceived effort, oxygen uptake, and less pleasure during treadmill exercise sessions (7). Recent theories suggest that a negative experience associated with exercise can significantly reduce the likelihood of engaging in future exercise sessions (8). Therefore, tools to reduce these barriers may improve outcomes for exercise-based interventions for morbid obesity. The Alter-G, an antigravity treadmill that alleviates body weight while subjects exercise, has potential to reduce pain and exertion during exercise. Overall, these treadmills have been found to be effective for weight loss in obese populations (10). However, although evidence suggests that the Alter-G would reduce pain and exertion, the effect of the Alter-G treadmill on exercise adherence in morbidly obese populations has not been studied. The hypothesis is that the adherence to and progression of the exercise routine of participants walking at a reduced percentage of their body weight will increase relative to those who must exercise at 100% of their body weight. A secondary hypothesis is that participants who use the Alter-G with the anti-gravity function will experience less pain and perceived exertion during exercise compared to those who exercise at 100% of their body weight. Finally, the investigators hypothesize that increased exercise adherence in those using the anti-gravity function of the Alter-G will lead to increased fitness and improved muscle function.
