Filter by:The aim of our study is to evaluate the efficacy of "60 meters 60 seconds exercise test" (a test designed by the study group) done preoperatively as a predictor test for postoperative intensive care unit need and extubation success in patients undergoing bariatric surgery.
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?
To evaluate the effectiveness of negative-pressure wound therapy in decreasing wound complications in morbidly obese patients (BMI greater than of equal to 40) at Albany Medical Center Hospital. Retrospective data will be collected regarding morbidly obese patients who have undergone cesarean section and patients will be recruited to have the intervention (negative-pressure wound therapy) applied and outcomes will be evaluated.
A prospective bariatric database was carried out in the Department of Digestive and Endocrine Surgery at the University Hospital of Strasbourg, France, starting in January 1996. All potential candidates for obesity surgery were prospectively registered in the database. Patients were informed by the bariatric surgeon of the prospective database, and of the possibility of utilizing personal data for research purpose after anonymization. A case-control study was performed, to compare the quality of life (QoL) of patients treated for internal hernia (IH group) with the QoL of patients with an uncomplicated course after Roux en Y gastric bypass (Uncomplicated RYGB group).
The purpose of this study is to evaluate the safety and effectiveness of left gastric artery embolization(bariatric arterial embolization) for morbid obesity. When the target vessel is blocked, some of the body's signals for feeling hungry will be suppressed and lead to weight loss. Although there are many ways to treat morbid obesity, surgery is currently the only effective method to be confirmed. But surgical treatment is likely to carry a high risk of treatment-related complications, such as fistula or intestinal obstruction, etc. This study is designed to help treat obesity using a method of transvascular interventional therapy, which is minimally invasive and non-surgical.
Sleeve gastrectomy is now the most commonly performed bariatric surgery. While many studies have evaluated factors that may minimize post-operative hemorrhage and staple-line leak, the investigators are unaware of any studies that compare outcomes between devices from the two main stapler manufacturers used in this surgery, Covidien and Ethicon. The purpose of this study is to compare intraoperative characteristics, such as time to create sleeve, intraoperative bleeding, and time needed to load each cartridge, and post-operative characteristics, such as any complication requiring readmission (leak or hemorrhage), further surgical intervention, and weight loss, between patients who underwent sleeve gastrectomy with Covidien devices and Ethicon devices. Currently the investigators predominantly use whatever device is cheaper, but cost should not be the primary decisive factor if one device is superior to the other. If one device has better clinical outcomes, it should be the preferred device regardless of cost. If neither proves superiority, the investigators can justify using cost to determine which device to use in patient care.
This is a long-term follow-up and interventional study in individuals who have been diagnosed with moderate to severe obesity with or without diabetes. The purpose of this study is to determine the effects of sleeve gastrectomy on weight and blood sugar control and underlying mechanisms by metabolomics, metagenomics, functional magnetic resonance imaging (fMRI) ,adipose tissue expression chip and etc.
Rapid onset Obesity, Hypoventilation, Hypothalamic dysfunction and Autonomic Dysregulation (ROHHAD) is a syndrome named in 2007. The hallmark of the syndrome is the rapid onset obesity and dysregulation of central ventilation. There is little information about the metabolic changes that lead to the rapid onset obesity in these children. The investigators would like to study the metabolic phenotype of these children to understand the disturbances in energy balance that lead to the rapid onset obesity.
Obesity is a major public health problem in developed and developing countries, causing a range of respiratory and metabolic changes. There is a strong correlation between obesity and cardiorespiratory sleep disorders. The weight loss reduces the comorbidities and improves the quality of life, but clinical treatment it is not effective for a long period. In this context, currently bariatric surgery is an option for the real weight loss in the long term. Obstructive sleep apnea (OSA) is a common clinical condition observed in patients with obesity. The primary aim of this protocol are to assess the inflammatory profile of severe obese patients undergone to bariatric surgery, through systemic and adipose markers of inflammation. A secondary objective is study the impact of this surgery on sleep variables and quality of life. Investigators hypothesized that weight loss induced by bariatric surgery reduces systemic inflammatory profile, improve sleep quality and quality of life of subjects with severe obesity. Will participate in this study, patients with severe obesity (BMI > 40 or 35 to 39.9 kg/m2 associated comorbidities), with indication of bariatric surgery, screened Bariatric Surgery Service of Santa Casa de São Paulo in São Paulo. Inclusion criteria are severely obese, bariatric surgery indication and agreement to participate in the study. Are excluded patients with BMI > 55 kg/m2, clinical instability, mental instability or significant and unrealistic expectations of surgery. Patients will be assessed before and after bariatric surgery, 90, 180 and 360 days. The evaluation protocol will consist of clinical history, vital signs, neck and waist circumference, clinical analysis of blood inflammatory markers, lung function tests, maximal ventilatory pressures, full overnight standard polysomnography, excessive daytime sleepiness scale, cardiovascular risk, quality of life and personal satisfaction questionnaires.
Risk factor of cholelithiasis is rapid weight loss after bariatric surgery and change in the gallbladder function which is secondary to surgery. Many observational studies support this fact, and a high incidence of 28% -71% after gastric bypass surgery (RYGB) was reported in them. According to another publication, the incidence of gallbladder diseases is 5-36% after jejunoileal bypass surgery and 2.8-36% after gastric bypass surgery.
