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.
Bariatric surgical procedures are associated with low short-term mortality and may be associated with long-term reductions in all-cause, cardiovascular, and cancer-related mortality. This surgeries are major surgeries include risk of mortality still. Melatonin is a hormone secreted from the pineal gland. Melatonin is an antioxidant, antinociceptive, hypnotic, anticonvulsant, neuroprotective, anxiolytic, sedative and analgesic. Melatonin is neurohormone with the profile of a novel hypnotic-anesthetic agent. The purpose of this study is to investigate the preoperative, perioperative and postoperative melatonin levels in bariatric surgery under general anesthesia and to investigate the relationship between melatonin level and analgesia requirement.
The primary objective of the study is to determine whether participation in a pre-bariatric surgery physical activity and behavior modification/education program (ENCOURAGEING START) that is tailored to the unique needs of obese bariatric surgery patients, improves physical fitness, surgical outcomes, patient health and quality of life. Short- (one year) and long- (five year) term outcomes will be compared to matched historical controls (1:1) based on age, gender, and body mass index (BMI) from the existing Manitoba Centre for Metabolic and Bariatric Surgery (CMBS) database. Our findings will determine whether a pre-bariatric surgery physical activity and behavior modification/education program results in improve surgical and patient outcomes and inform the development of evidence-based physical activity (PA) guidelines for bariatric surgery patients and improved CMBS program delivery.
After gastric sleeve patients undergo a substantial weight loss, but the physiological mechanisms behind the weight loss is not fully elucidated. Studies suggest that gut-hormone secretion is altered comparable to what is also seen after Roux-en-Y gastric bypass, however to which extent is not fully established and furthermore, the mechanisms behind an altered secretion are unclear. The purpose of this study is to investigate absorption and postprandial metabolism of glucose and protein in addition to gut hormonal responses after gastric sleeve compared with a group of un-operated subjects machted on sex, age and BMI. Furter, a group of Roux-en-Y gastric bypass operated patients matched on pre-operative BMI, current BMI, sex and age will be included for comparison.
The Sleeve Gastrectomy (SG) is a bariatric surgery procedure performed by laparoscopic booming in recent years. This is an effective intervention on weight loss over the long term with few early postoperative complications and low morbidity in the long term. Obesity is considered as a risk factor for hernia full after surgery by laparoscopy with a relative risk of 29% in connection with cholecystectomy. Several series showed a rupture rate on trocar from 0 to 0.7%, but each time with a clinical evaluation. Recently, it was shown eventrations rate between 26 and 38% under the Roux-en-Y gastric bypass with a rupture rate increased on epigastric trocar. The assessment in the context of this series was ultrasound. Recent data suggest that the absence of closure of the epigastric trocar of 12mm through an SG of first intention was associated with a hernia rate of 17% with a scannographic evaluation. Also, recently, Tabone suggests that the systematic closure of the epigastric trocar site would not be as effective as lateralize inserting the trocar from the white line of the abdomen. Change the positioning of this trocar induce an additional difficulty in handling instruments for the realization of the SG with an désaxassion instruments, a conflict between the instruments for the realization of the SG and the optical laparoscopy.
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.
an examination of the different aspects of bariatric surgery in elderly in comparison with non-elderly patients.
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.
