The purpose of the study is to compare dietary habits after bariatric surgery in patients with poor weight loss versus good weight loss outcomes.
Background: Bone fragility is a complication of type 2 diabetes. Diabetes treatments may ameliorate or deteriorate bone fragility in this population. Bariatric surgery is gaining in popularity in people with type 2 diabetes and may impact bone health. Objectives: To evaluate the impact of the most popular bariatric procedure worldwide (sleeve gastrectomy (SG)) on vBMD by QCT in patients with type 2 diabetes; Secondary aims: (1) to identify the determinants of vBMD after bariatric surgery in patients with type 2 diabetes; (2) to compare vBMD and its potential determinants after bariatric surgery with obese controls without diabetes as well as with controls without obesity and normoglycemia.
Bariatric surgery is the only treatment with long standing effect of morbid obesity. The key elements to success are the patient-selection, an experienced bariatric team and a completed follow-up program. Follow-up programs can consist of, for example, providing social support in support groups, teaching psychological skills, such as coping with the body change or teaching self-regulation of body weight. Furthermore, follow-up is important for dietary and sports counselling. The experience of the team members and coaching skills are essential in indicating the suitable procedure if necessary and guide the patients through the process. Various studies showed a significant positive effect of a completed follow-up program after bariatric surgery on maintaining weight loss. There is a burden for this on site provided care as organizational and financial resources are not unlimited. Especially as the follow-up period is an obligatory 5 years or if possible life long. Even if this aftercare is provided, not all patients complete the complete program. Various reasons are possible for an increasing no-show-rate, the loss of enthusiasm for onsite visits could be one of them. Analogue to other chronic diseases, the addition of telehealth could be useful. Telehealth is the delivery of health-related services and information via telecommunications technologies. It encompasses preventative, promotive and curative aspects. Examples are exchanging health services or education via videoconference, transmission of medical data for disease management (remote monitoring) and advice on prevention of diseases and promotion of good health by patient monitoring and follow-up. The participation of eHealth has been investigated and considered useful in the treatment of obesity. In a systematic review self-measured blood pressure monitoring was associated with better control of hypertension at least in the first year. Its value in a bariatric tract has not been investigated. It can be hypothesized that self-control by eHealth could enhance clinical outcome as more weight loss and comorbidity reduction. Long-term realistic goals setting, consistent use of routines and self-monitoring has been proven effective for weight loss maintenance. Patients with higher self-control are more certain regarding their abilities, which cause higher commitment and adherence to the program. This eventually leads to more weight loss. For this purpose an online monitoring program was designed for our Obesity Centre (BePATIENT) to provide preoperative information as well as aids in the post-bariatric phase by self-control wireless devices for registration of biometric outcomes, teleconference opportunities and access to additional information. In a prospective trial the implementation in several degrees is evaluated.
This clinical trial is a monocentric, prospective, observational and controlled trial (historical cohort control group of healthy non-obese subjects who had Nasal functional exploration for Snoring) as part of current care. This study concerns the prevalence of obstructive sleep apnea syndrome (OSAS). OSAS is elevated in subjects with morbid obesity (BMI≥40) (on average 70%). International recommendations agree on the need to seek OSAS before bariatric surgery because of the high risk of complications. Increased nasal resistance could also be related to a limitation of inspiratory flow due to an abnormality of the elasticity of the nasal mucosa or "nasal compliance". Adipose infiltration of the nasal mucosa may occur during obesity. These tissue changes (decreased vaso-erectile tissue and increased adipose tissue) could modify the nasal compliance, which the decrease would be a possible factor of severity of OSAS in obese patients. Screening for an abnormality of compliance could also anticipate a difficulty of equipment for Continuous Positive Airway Pressure (CPAP) in the case of associated OSAS. All patients who must have bariatric surgery and get in the criteria are included. They will have to do a medical checkup pre and post-operative (polygraphy + ear/nose/throat assessment (ENT) + Nasal functional exploration). They will be followed for 13 to 24 months. The main objective of this research is to demonstrate a reduction of at least 30% of nasal compliance in a group of obese subjects (BMI> 35) compared to a control group of healthy subjects. The secondary objectives are to is to demonstrate an increase of 30% in resistance in patients with BMI> 35 compared to control group and a normalization of nasal compliance 1 year after surgery when their weight is normalized (BMI <30). A study period of 4 years is planned.
This study compares the two mechanical ventilation strategies in obese patients undergoing bariatric surgery: pressure-controlled ventilation(PCV) and pressure-controlled ventilation volume-guaranteed（PCV-VG). This is a randomized controlled trial with a sample size of 100 patients whose body mass index(BMI) is over 30kg/m².
The aim of this cohort study is to collect prospectively clinical data on all the patients admitted in the investigators department for bariatric surgery or for any complication of a bariatric procedure. The investigators goal is not only to improve the follow-up but also to assess and publish the investigators results regarding weight loss and the complication rate.
This long-term, nationwide observational data collection repository will obtain patient-reported outcomes from metabolic and bariatric surgery patients. The data will be used in conjunction with clinical outcomes to determine quality, safety, and comparative effectiveness of various metabolic and bariatric procedures.
Obesity is a non-communicable chronic disease of multifactorial, involving biological, historical, ecological, economic, social, cultural and political. Currently, bariatric surgery is considered an effective method of refractory obesity treatment, and only severe obesity effective treatment that leads to reduced long-term weight. It is well documented in the literature regarding the association of abdominal surgery and the incidence of respiratory complications and its main characteristics are: atelectasis, pneumonia, respiratory dysfunction and pleural effusion. All these respiratory complications can be minimized or avoided with the use of a respiratory therapy care protocol, since the pulmonary atelectasis is considered the main cause of complications. An arsenal of resources to physical therapy lung expansion, among these, the application of positive pressure through a valve EPAP (Expiratory positive airway Pressure) and the use of noninvasive ventilation, and aims to prevent and / or improve the complications resulting from postoperative. The electrical impedance tomography (EIT) is an alternate to allow assessment of the respiratory system, without suffering the same interference conditions of patients, such as pain and bed rest. TIE consists of a method that measures passively regional lung ventilation. The aim of this study is to compare the effects of the application of EPAP and NIV on pulmonary ventilation we post bariatric surgery. This is a randomized controlled trial where patients will be divided into two groups: EPAP and NIV and assessed by spirometry, manometer and TIE. The techniques will be applied in the 1st and 2nd postoperative day where they will be evaluated before, during and after the application of the techniques.
The purpose of this study is to determine whether deep neuromuscular blockade compared to moderate neuromuscular blockade may improve the surgical conditions in patients undergoing laparoscopic bariatric surgery.
