Filter by:Lung ultrasonography is an easy-to-use, portable, non-invasive, visual, and non-radiative technique that has been widely used in clinical monitoring and diagnosis. Many studies have demonstrated that pulmonary ultrasonography can evaluate the degree of aeration loss and diagnose atelectasis accurately by using a validated semiquantitative score in the perioperative period, and lung ultrasonic imaging can be conducive to confirming the effects of lung recruitment manoeuvres. This clinical trial suggested that the use of ultrasound-guided recruitment maneuver in morbidly obese patients scheduled for laparoscopic bariatric surgery can improve the lung aeration, decrease the incidence of basal lung atelectasis, decrease the incidence of intraoperative& postoperative oxygen desaturation, and reduce the incidence of post operative pulmonary complications. The aim of this prospective randomized clinical study is to compare the conventional recruitment manoeuvre and ultrasound-guided recruitment manoeuvre in morbidly obese patients scheduled for laparoscopic bariatric surgery.
The purpose of this study is to To determine the effect of warm and humidified (WH) carbon dioxide (CO2) on post-operative pain/analgesia requirement in patients undergoing laparoscopic bariatric surgery.
The goal of this pilot prospective interventional study is to evaluate the efficacy of endoscopic sleeve gastroplasty (ESG) in allowing obese subjects with the need of liver transplantation to reduce their BMI in order to enter the waiting list (BMI (≥35 kg/m2). The main question[s] it aims to answer are: - Is the procedure effective in reducing BMI to the target level in 12 months? - Which is the effect on weight loss, quality of life and obesity-related comorbidities? Participants will undergo ESG as per standard clinical practice and followed up to 12 months before transplantation and for 12 months after transplantation
Total body weight loss (TBWL) after bariatric endoscopy (BE) is variable. Gastric emptying may be normal, rapid or delayed in patients with obesity and be a factor in variable BE outcomes. Gastric myoelectrical activity (GMA) reflects gastric pacemaker activity which controls gastric contractions. The non-invasive electrogastrogram(EGG) uses standard electrodes positioned on the abdominal surface to record GMA. The investigators postulate that GMA patterns recorded with EGG will reflect subgroups in regards to stomach electrical physiology in obesity and that these subgroups will be useful in selecting patients for various BE procedures to maximize success of the procedures.
To study the glycemic patterns of patients undergoing bariatric surgery and what are the risk factors capable of predicting episodes of unnoticed hypoglycemia and high glycemic variability, evaluating patients who underwent reduction gastroplasty with Roux-en-Y reconstruction (GRYR) and sleeve gastrectomy (SG)
In patients with severe obesity, bariatric surgery provides consistent and long-term weight loss. BMI ≥50kg / m2 is an independent factor of increased morbidity / mortality in bariatric surgery compared with patients weighing less than 50 kg / m2 (1.2% and 0.8%) mainly due to technical difficulties. Preoperative weight loss reduces this morbidity / mortality. Recent studies have shown that blocking blood vessels to a particular portion of the stomach (bariatric or left gastric artery embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and result in weight loss. The purpose of this study was to evaluate the safety and effectiveness of the association bariatric embolization before sleeve gastrectomy in super obese patients.
The purpose of this research is to determine patient-reported outcomes after weight loss surgery, including changes in health, mood, quality of life, health satisfaction, and emotional health, in low-risk patients. Weight loss surgery has been well studied for patients with body mass index (BMI) 35 kg/m^2 or more and those with weight-related medical problems who have a BMI 30 kg/m^2 or more. However, outcomes after weight loss surgery in patients with BMI under 35 kg/m^2 and without co-morbidities have not been well studied.
Morbid obesity is defined as a complex chronic condition in which a person presents a body mass index above 40 kg/m2. This disease increases the risk of several co-morbidities and entails a reduction in life expectancy of 10 years. Its prevalence is increasing in developed countries and bariatric surgery has been suggested to be one of the best tools to counteract it. Nonetheless, this surgery also presents negative effects such as loss of bone mineral density (BMD) and muscle mass and an increased fracture risk. The aim of the present study is to elucidate the effects of surgery and a whole body vibration training (WBV) on body composition, physical fitness, microbiota and cardiometabolic markers. Twenty eight participants will undergo bariatric surgery and will be randomly allocated into a control group or a WBV group. The whole body vibration group will have a duration of 4 months in which participants will train three times per week (30 minutes per session). Measurements of body composition (dual energy x-ray and peripheral quantitative computed tomography), physical fitness (muscular strength, aerobic fitness and balance), gait biomechanics, cardiometabolic markers, gut microbiota, quality of life and physical activity levels will be registered in four different timepoints (1. Before the intervention, 2) 45 days after the surgery, 3) Six months after the surgery, and 4) 18 months after the surgery. The cost of the surgery and the exercise program will also be calculated to perform a cost-effectiveness analysis.
Insulin resistance is a key feature of postoperative metabolism, leading to decreased glucose absorption in adipose tissue and skeletal muscle, with an increased glucose release due to hepatic gluconeogenesis and hyperglycemia. Development of insulin resistance is associated with increased length of hospital stay (LOS), morbidity, and mortality. One of the strategies employed to reduce the postoperative stress response and perioperative insulin resistance includes the reduction of the preoperative fasting time via preoperative carbohydrate oral (CHO) drink. Preoperative carbohydrate intake is an integral part of the Enhanced Recovery After Surgery (ERAS) protocol and previous studies have shown that preoperative carbohydrate loading can increase patient comfort. Although ERAS protocols are increasingly used and implemented in bariatric surgery centres specific components of these protocols, such as preoperative oral carbohydrate nutrition, have not yet been rigorously analyzed. The aim of this prospective study is to compare the differences in patient outcomes between preoperative CHO loading and a conventional fasting protocol. The secondary aim is to perform a subgroup analysis of Roux-en-Y bypass and sleeve gastrectomy.
The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.
