Filter by:Due to anatomical and physiological changes caused by the Roux-en-Y gastric bypass (RYGB) bariatric surgery, drug bioavailability after the surgery can be altered. Therefore, post-operative dose adjustment in these patients can be required. The aim of the study was to investigate the effects of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery on drug pharmacokinetics and cytochrome P450 (CYP) mediated metabolism using a cocktail of nine CYP probe drugs. The cocktail covers nine main CYP enzymes: melatonin (CYP1A2), nicotine (CYP2A6), bupropion (CYP2B6), repaglinide (CYP2C8), losartan (CYP2C9), omeprazole (CYP2C19/CYP3A4), dextromethorphan (CYP2D6), chlorzoxazone (CYP2E1), midazolam (CYP3A4). The changes in pharmacokinetic parameters of the drugs as well as modulation of the activity of CYPs are evaluated before and one year after LRYGB. In the study, the patients administering drug cocktail before surgery and 1 year after LRYGB are served as their own controls.
The objective of the clinical study was to examine if practice could improve walking patterns associated with fall risks before patients with obesity underwent weight loss surgery. We hypothesized that patients would show improvements in their walking after completing the intervention. For the intervention, patients walked under five conditions: on flat ground at the beginning of the study, crossing three obstacle heights, and on flat ground at the end of the study for a total of 25 times.
As bleeding is a major risk in bariatric surgeries, we aimed our study to find any predictors to such bleeding within the surgery or 30 days after surgery. The study is a retrospective study collecting patients data, surgeons data, and hospitals data in order to find if any of the factors influencing patients, surgeons or hospitals, has to do with bleeding in these surgeries and if it does impact bleeding in what way. The goal is finding a predictor that it's neutralizing may prevent bleeding in bariatric surgeries.
Endoscopic complications such as gastro-esophageal reflux disease, ulcera, gastritis, bile reflux, anastomotic stricture and so on are described after gastric bypass surgery. The incidence of these complications after RYGB versus MGB/OAGB are getting observed.
Rapid metabolic improvements seen with sleeve gastrectomy are likely a result of changes in gastric origin. The gastric mucosa is an endocrine organ that regulates satiation pathways and is a complex regulator of food intake as well as lipid and glucose metabolism. This study aims to assess the efficacy and safety of endoscopic selective gastric mucosal devitalization (GMD) for the management of obesity and its related comorbidities.
The purpose of this study is to evaluate the safety and effectiveness of the Levita Magnetic Surgical System in patients undergoing bariatric procedures
This study compares the intraoperative opioid free anesthesia approach in laparoscopic bariatric surgery to a conventional opioid- based anesthesia. Half of participants will receive opioid free anesthesia with dexmedetomidine, lidocaine and ketamine while the other half will receive opioid based anesthesia with fentanyl, remi-fentanyl and ketamine
Severe/morbid obesity is an international public health issue that importantly increases the risk of cardiovascular events and cardiovascular and all-cause mortality. Likewise, severe/morbid obesity increases the risk of illness, reduces quality of life, and raises health-care costs. Bariatric surgery is the election method for the treatment of severe/morbid obesity, resulting in significant weight loss and remission of comorbidities. However, a relatively large proportion of bariatric patients regain weight and continue to be at high risk for cardiovascular disease and premature mortality. A healthy lifestyle following bariatric surgery is essential for optimizing and maintaining weight loss. Observational studies suggest that physical activity following bariatric surgery might be associated with additional weight loss and more effective weigh loss maintenance over time. However, very little experimental evidence exists regarding the effects of supervised exercise on obesity-related outcomes in this specific population. The aim of the EFIBAR (Ejercicio FÍsico tras cirugía BARiátrica) randomized controlled trial is to determine the effects of a 16-week supervised concurrent (aerobic and strength) exercise intervention program, on weight loss (primary outcome), body composition, cardiometabolic risk, physical fitness and quality of life (secondary outcomes) in patients with severe/morbid obesity following bariatric surgery. According to the study aims the investigators pursue the following hypothesis: Supervised exercise will result in larger weight loss than control.
Changes in homocysteine values after bariatric surgery remain controversially discussed. This is the first comprehensive summary to depict timeline changes in homocysteine levels following laparoscopic roux-en-Y gastric bypass.
The present study has a prospective, longitudinal and observational character, will be performed with patients attending a private clinic specialized in the treatment of obesity and bariatric surgery. Patients to be analyzed should have a medical indication for bariatric surgery.
