Reliability Assessment and Design of Procedures and Devices in Bariatric Surgery: An Engineering Approach
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2018, Vol 8, Issue 5
Abstract
Bariatric surgery is the most effective intervention for severe obesity, as one of the most serious health problem worldwide. Laparoscopic adjustable gastric banding is one of the principal technique. Nonetheless, side effects are frequent and weight-loss is not always successful. Non- optimal intervention design, surgery invasiveness and general anesthesia are the principal cause of this situation. A more advanced approach is required, integrating bioengineering and medical competences, aiming to engineering design the procedure, to improve efficacy and to reduce the need for anesthesia. Computational methods can be exploited to evaluate stomach functionality after surgery and to interpret mechano-biological processes, aiming at the optimal design of the intervention. Results from coupled experimental and computational activities are here reported, showing the potentialities of the engineering approach. Endoscopic surgery should minimize invasiveness and anesthetic requirement, but previously proposed techniques demonstrate marginal efficacy. Procedural consistent advances are required, as devices designed to provide endoscopic gastric banding. Preliminary results from computational activities are proposed, again to show the capabilities of the engineering approach to mimic and to optimize the overall surgical procedure.OBESITY is an epidemic disease associated with multiple co-morbidities, whose prevalence in developed countries is increasing. The United States spend million dollars annually on treatment and prevention. It has been estimated that 30% of adults in the US meet the criteria for obesity and also in Europe obesity is common [1]. Several surveys show that the prevalence of overweight among school age children is as high as 40% in parts of Europe. The World Health Organization and health agencies in most countries report epidemiological data showing an increase in morbidity and mortality because of increasing weight. Major obesity related diseases include increased risk for cardiovascular diseases, dyslipidemia, diabetes mellitus, cancer, and psychosocial impairment. These conditions are responsible for more than 2.5 million deaths per year worldwide. The loss of life expectancy is profound [2]. Bariatric surgery remains the most effective intervention for patients with body mass index (BMI) of 40 kg/m2 or greater or those with BMI of 35 kg/m2 or greater with specific related co-morbidities [3].
