Bariatric surgery is a collective term for several weight-loss surgeries. Essentially, the surgery involves making modifications to one’s digestive system to facilitate weight loss. Often, bariatric surgery is performed when exercise and diet have failed to procure noticeable results or when an individual faces serious health issues because of excess weight.
While some bariatric surgeries limit the amount of diet intake, others work by reducing the body’s ability to absorb nutrients. That said, one bariatric surgery that is extremely effective in weight loss is a modified duodenal switch with single anastomosis. It is an adapted and less invasive form of the original duodenal switch procedure which is also referred to as SADI or SIPS.
This type of bariatric surgery to performed to limit your food intake as well as the nutrient amount you consume. In this post, we will understand this bariatric surgery in detail. So, let’s begin.
What Is SADI?
SADI is a modified and simplified version of the duodenal switch. In this, a sleeve gastrectomy is performed and then, the stomach is redirected and connected to the lower part of the small intestine, thus reducing your desire to eat. After the surgery is performed, the individual requires smaller quantities of food to feel satiated.
The concept behind the surgery is that when a large section of the stomach is removed, one tends to consume lesser quantities and absorbs fewer calories.
Difference between SADI and Duodenal Switch
SADI is a procedure in which only 60 to 75% of the small intestine is bypassed. Anastomosis implies that only one connection is formed instead of two, which is what distinguishes this surgery from the duodenal switch.
Typically, the regular duodenal switch is performed in the following way:
A sleeve gastrectomy is performed in which almost 80% of the stomach is sidestepped, leaving a tube-shaped stomach that resembles a banana. Finally, a large part of the small intestine is removed by connecting the end part of the intestine to the duodenum present near the stomach.
Generally, the duodenal switch surgery is performed as a single procedure. However, in a few cases, it is performed as two separate surgeries: sleeve gastrectomy and intestinal bypass.
On the other hand, in the SADI procedure, only a sleeve gastrectomy is created to control hunger and appetite. Once the sleeve is created, the intestine is redirected and not removed. Thus, only one connection is made instead of two connections as in the traditional duodenal switch. And with just one connection, the SADI procedure is completed much faster.
How Does SADI Work?
In SADI, the part of the stomach that secretes ghrelin is mostly removed. Ghrelin is a hormone that triggers the feeling of hunger. When the part producing this hormone is removed, an individual tends to feel satiated most of the time.
Apart from that, the upper half of the small intestine is also bypassed. With this, the consumed food is sidestepped which in turn, reduces the number of calories and nutrients absorbed by the body. Lastly, the consumed food fills up a big portion of the intestine, creating a feeling of fullness. And all these things work in synergy to reduce appetite and lose weight.
Things to Consider Before Opting for SADI
Although SADI is an incredible procedure, it is always recommended as the last resort for people who do not gain results from diet or exercise. It must only be performed when it is absolutely necessary as it may come with several risks.
The original version of duodenal switch surgery was deemed to be much more troublesome and problematic. In several cases, it was known to cause loose bowel movements, severe malnutrition, and intestinal leakage. However, SADI has addressed a lot of these shortcomings for most people. Yet, it is important to consult a good and specialized surgeon before planning to get the operation.
Lastly, it is crucial to understand the anticipated results as well as the recovery process involved in getting a SADI procedure. In most cases, the patients have to stay under observation for at least 48 hours. It is also important to take adequate rest and abstain from lifting heavy objects for two weeks after the surgery.
SADI is an excellent bariatric surgery that helps people lose 80-90% of their excess weight during the first year of surgery. In comparison to the duodenal switch, it ensures quicker recovery and a lesser invasive procedure. You must make sure to find a good surgeon who can provide first-class individual care with personalized attention.
