Active clinical trials for "Obesity, Morbid"

PURPOSE Obesity is a growing problem in the United States. Severe obesity, known as "morbid obesity", is defined as being 100 pounds in excess of ideal body weight. Nonsurgical treatments for morbid obesity include exercise, dietary restriction, behavior modification, and pharmacological intervention. However, it is estimated that most patients undergoing nonsurgical treatments for weight reduction will regain their weight within 2 to 4 years after treatment. According to the NIH consensus conference in 1991, surgery remains the only effective sustained weight loss treatment for morbid obesity. The Roux-en-Y gastric bypass (GBP) is currently considered the gold standard bariatric surgical operation. Mean weight loss following GBP is approximately 65% of the excess body weight during the first 12 to 18 months postoperatively. Long-term weight loss is in the range of 55-70% of excess body weight loss. Recently, the laparoscopic approach to GBP was reported. Wittgrove and colleagues reported their results of 75 patients who underwent laparoscopic GBP and demonstrated significant short-term advantages with comparable weight loss and reversal of comorbidities compared to the open approach. However, GBP might it be done laparoscopic or open approach can potentially be associated with significant morbidity and mortality such as anastomotic leak, pulmonary embolism, bowel obstruction, and postoperative stricture. The FDA recently approved the laparoscopic adjustable banding system (LAP-BAND) for use in the United States in June 2001. The LAP-BAND system is a device designed to induce weight loss in severely obese patients. It is surgically placed around the proximal stomach to create a small proximal stomach pouch and restricted opening, or stoma, through which passage of food will be slowed. An inflatable portion along the inner aspect of the band is connected to an access port, placed intramuscularly. This enabled stoma adjustments to be made without the need for further surgery. The advantages of the LAP-BAND system included no cutting or opening of the stomach wall, ability to adjust the stoma and a technically easier operation to perform than laparoscopic GBP. We wanted to evaluate if the LAP-BAND procedure is as effective as the laparoscopic GBP procedure for treatment of morbid obesity.

A quasi-experimental study developed in sedentary morbidly obese men and women (age 43.6±11.3 y; body mass index [BMI] ≥40 kg/m2) were assigned to a CT group of ET plus RT (ET+RT; n=19; BMI 47.8±16.7) or RT plus ET order group (RT+ET; n=17; BMI 43.0±8.0). Subjects of both groups received eight exercise sessions over four weeks. Systolic (SBP), diastolic (DBP), mean arterial pressure [MAP], heart rate at rest [HR], and pulse pressure [PP] measurements before and after 10 minutes postexercise. Secondary outcomes were other anthropometric, body composition, metabolic, and physical condition parameters. Using the ∆SBP reduction, and quartile categorization (Q) in 'high' (Rs: quartile 4), 'moderate' (MRs: quartile 3), 'low' (LRs: quartile 2), and 'nonresponders' (NRs: quartile 1) were reported.

The main aim of this study is to elucidate the mechanism of the remission of type 2 diabetes in the morbid obese patients after laparoscopic sleeve gastrectomy.

Introduction RYGB surgeon; Have become increasingly morbid obesity treatment methods with improvements in minimally invasive surgery. Ensuring patient comfort and early return to life are the criteria that should be given priority in this treatment method.The purpose of this study; Emphasizing that the cautery technique of the stapler line bleeding control methods is as successful as the other methods.

The aim of this study is to compare two postoperative recovery pathways namely, enhanced recovery after surgery (ERAS) pathway and conventional recovery pathway after laparoscopic sleeve gastrectomy with respect to outcomes including hospital stay, postoperative pain and other postoperative outcomes.

Leakage is the most common complication after laparoscopic sleeve gastrectomy which may amount to 20% in some studies. We hypothesize that Clostridium botulinum neurotoxin A (BTX-A) injection into the pyloric sphincter during the operation may decrease the risk of postoperative gastric leakage.

Although previous studies investigated weight loss and improvement in comorbidities after SASI bypass, patients included in these studies had a BMI less than 50 Kg/m2. Therefore, the aim of the present study was to investigate the outcome of SASI bypass in patients with super obesity to assess the success of this novel bariatric procedure in this challenging group of patients in regards weight loss and improvement in associated comorbid conditions at 12 months postoperatively.

The aim of this study is to determine the ED90 of hyperbaric intrathecal bupivacaine for the super obese population undergoing cesarean section under a combined spinal epidural technique.

This study investigated the use of Tai Chi as a feasible form of physical activity for women with morbid obesity utilizing an instructional digital video disc (DVD). Two groups of women with morbid obesity (body mass index of >40) were placed into the Tai Chi intervention group or the control group. Initial function was assessed with a series of tests and then repeated after 8 weeks. During the 8 weeks, the Tai Chi intervention group met once a week for 45 minutes to participate in a group exercise class. The control group was asked to continue their regular activity. At the end of the 8 weeks, both groups were reassessed with the same tests from the start of the study. The investigators hypothesized that the Tai Chi group would show more improvement in their functional scores for strength, balance and quality of life than the control group.

Sleeve gastrectomy is a stapler dependent bariatric procedure. A hand-sewn sleeve gastrectomy can be necessary under certain circumstances. Here, the investigatorsaimed to compare the outcomes of hand-sewn and stapled sleeve gastrectomies for the first time. In the hand-sewn group, no staplers were used and after vertical resection of the stomach by energy devices, the remnant stomach was closed by two rows intracorporeal sutures. In the stapler group, sleeve gastrectomy was done in the usual way.
