Filter by:Laparoscopic sleeve gastrectomy is widely employed nowadays. Multimodal analgesia approach is implemented within the enhanced recovery protocol in our facility to improve participants' recovery. Due to side effects of narcotics, the may adversely affect the quality of recovery, the investigators intended to test the efficacy of opioids free anaesthesia on the quality of recovery and postoperative narcotic use.
The purpose of this clinical trial is to study the effects of resistance training program on physical-functional fitness, muscle mass and strength, endothelial function, blood pressure, biochemical markers of cardiovascular risk and bone metabolism, density and microstructure and quality of life of post-bariatric patients (Study 1). To compare the bone and muscle changes in post-bariatric patients by Roux-en-Y Gastric Bypass Surgery with non-bariatric controls, as well as to correlate these health indicators with surgery time and weight loss (Study 2).
The bariatric surgery is recommended for treatment of patients with severe obesity, resulting in greater weight loss and improvement of cardiovascular and metabolic comorbidities. However, weight regain is observed in patients after surgery, leading to health adverse outcomes. The purpose of this study is to identify the rate of weight regain and predictive factors of regain in bariatric patients without outpatients care regular.
The aim of the study is to evaluate the effect of erector spinae plane (ESP) block on postoperative analgesic consumption in patients undergoing laparoscopic bariatric surgery
Data on pharmacokinetics of rivaroxaban after bariatric surgery and in morbid obesity are sparse. The aim of this study is to assess the pharmacokinetic and pharmacodynamic parameters of rivaroxaban, used at a therapeutic anticoagulant dose, in patients with previous bariatric surgery, with sleeve gastrectomy or gastric bypass, and in morbid obese subjects. Four groups of 16 subjects per group are studied: Morbid obese subjects / Subjects who have undergone gastric bypass surgery / Subjects who have undergone sleeve gastrectomy surgery / Non-operated control subjects matched for age and BMI with operated subjects. All patients (obese, surgical patients, and controls) will receive rivaroxaban 20mg once daily during 8 days. Blood samples will be taken predose (Baseline) and 0.5, 1, 2, 3, 6, 9, 12 and 24h post rivaroxaban administration at day1 and day8. PK and PD parameters will be compared between groups in order to explore the impact of bariatric surgery, type of surgery and body mass index on the pharmacological profile of rivaroxaban.
The goal of this pilot study is to establish the feasibility and initial efficacy of the combination of phentermine and topiramate for adolescents and young adults who require additional risk reduction after bariatric surgery. This study will use a randomized, placebo-controlled, double-blinded design to evaluate an adjunctive 12-week intervention of phentermine + topiramate + standard of care vs. placebos + standard of care 6 months after bariatric surgery, among 12 to 24 year olds who don't achieve expected weight loss or who remain severely obese (n=10 total).
Our hypothesis is that decreased concentration of ghrelin after LSG is important for the decreased appetite and food intake postoperatively. We therefore expect infusion of ghrelin will increase an ad libitum food intake after LSG. We also expect that a decreased postprandial concentration of ghrelin after LSG play a role for increased insulin secretion and decreased postprandial plasma glucose concentrations after surgery.
Addition of transverse abdominis plane (TAP) block to general anesthesia for morbidly obese patients (BMI >35) undergoing laparoscopic bariatric surgery for weight loss will significantly reduce opioid use in the recovery room
Enhanced recovery programme (ERP) includes early postoperative mobilization and ambulation the day of surgery. Data suggest that orthostatic symptoms prevent a large number of patients from ambulating the day of surgery. The investigators plan to include 50 patients scheduled for colorectal surgery and bariatric surgery in an ERP. A 6-min walk test (6MWT) will be performed before surgery, 3 hour after the end of surgery, and 24 hour after surgery. The day of surgery a 2-min walk test will be realized.
The aim of this study is to assess the indications for revisional bariatric surgery and short-term revisional surgical outcomes such as weight loss, BMI variation, % excessive weight loss and % excessive BMI loss .Prospectively-collected patient data will retrospectively reviewed. Patient demographics, body mass index (BMI), primary and revision surgery types, indications of revision, outcomes of revisional surgery and follow-up data for comorbidities will investigated.
