The SADI-S is a single anastomosis bariatric surgery. It is different from the classic duodenal switch, the gastric bypass (RNY) or sleeve gastrectomy.It is a type of bariatric surgery carried out to lose weight and to mitigate various metabolic issues including type 2 diabetes, dislipidemia, metabolic syndrome, and polycystic ovary syndrome.
The MGB has been suggested as an alternative to the Roux-en-Y procedure due to the simplicity of its construction and is becoming more and more popular because of low risk of complications and good sustained weight loss. It has been estimated that 15.4% of weight loss surgery in Asia is now performed via the MGB technique. [journal 6]
About 30% of those who undergo VBG achieve normal weight, and about 80% achieve some degree of weight loss. Most studies have suggested that 10 years after surgery, only 10% of patients maintain a minimum weight loss of at least 50% of their total excess weight at the time of their initial surgery. Some patients regain weight.
The yield calculation will determine the safety factor until the part starts to deform plastically. The ultimate calculation will determine the safety factor until failure. In brittle materials the yield and ultimate strengths are often so close as to be indistinguishable, so it is usually acceptable to only calculate the ultimate safety factor.
With the increase in the number of weight loss surgeries performed every year, [3] there are growing numbers of individuals who have experienced an unsatisfactory result from their bariatric procedures. There are several weight loss surgery options, [4] some of which may limit later options for revision weight loss surgery. [5]
[8] [9] In many cases, sleeve gastrectomy is as effective as gastric bypass surgery, including improvements in glucose homeostasis before substantial weight loss has occurred. This weight-loss independent benefit is related to the decrease in gastric volume, changes in gut peptides, and expression of genes involved in glucose absorption. [10] [11]
The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing ...
The Herschel–Bulkley fluid is a generalized model of a non-Newtonian fluid, in which the strain experienced by the fluid is related to the stress in a complicated, non-linear way. Three parameters characterize this relationship: the consistency k, the flow index n, and the yield shear stress . The consistency is a simple constant of ...
