There is an endless amount of information surrounding weight loss, dieting, and well-being constantly flying around us on the internet. Every time we check Instagram, there is a new influencer spouting the benefits of a different laxative tea. There are also a plethora of reasons as to why you might be struggling to lose weight. In such a world, it is important that you come to the right place for your information, and consult with experts that have extensive experience, and understand how your body really works.
You can rely on the team at Perth Weight Loss and Surgery, to provide you with all the facts, advice, and support that you may need in your weight loss journey and bariatric surgery experience.
When we understand something, there is no need to be anxious about it. We know the importance of our patients being well-informed. We recognise that the different weight-loss surgeries can sometimes bring about some misconceptions or sound confusing, the names may all sound similar to one another, or overly filled with medical jargon. Therefore, read on to find some clarity about the differences between each surgery.
A Lap Band Surgery entails the creation of a small pouch at the top of the stomach, with the placement of a silicon-based band, the size of which can be adjusted throughout the patient’s weightloss journey.
A Gastric Bypass surgery entails a small part of the stomach being surgically sectioned off, to create a small pouch at the top of the stomach and reconnecting small bowel to this pouch. Effectively reducing the size of the stomach, and therefore decreasing the appetite.
A Gastric Sleeve Surgery entails the surgical sectioning of a vertical, tube-like pouch from the stomach. This effectively removes the use of 80-90% of the stomach. The remaining sleeve of the stomach is still connected normally to the intestine, however, the stomach now holds only one tenth of what it could before the surgery.
Key Difference between Lap Band Surgery, Gastric Bypass and Gastric Sleeve:
The main difference that defines each of the aforementioned weight loss surgeries, is the method by which the stomach size is reduced. The resulting level of weight loss also differs between each procedure.
Your surgeon will advise you upon which surgery is most suited to your body type, your medical history and the goals for your weight loss journey.
The acronym SADI-S stands for Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy. This procedure is also known as SIPS, an acronym that stands for Stomach Intestinal Pylorus-Sparing Surgery. Some surgeons refer to this procedure as a “super-charged gastric sleeve surgery”.
The first step of a SADI-S/SIPS procedure includes the sleeve gastrectomy. The sleeve gastrectomy is essentially the same process of creating a Gastric Sleeve, as aforementioned.
Please see the Summary of Gastric Sleeve Surgery above.
However, this procedure differs from a simple Gastric Sleeve surgery, in the second step.
Essentially, the second step shortens the small intestine. There are three sections to the small intestine. In this surgery, the intestine is surgically detached from the end of the first section of the small intestine and then reattached to the start of the third section of the small intestine. Therefore, the middle section of the small intestine is bypassed.
The acronym SASI-S stands for Single Anastomosis Stomach-Ileal Bypass with Sleeve Gastrectomy. The SASI surgery differs only slightly from the SADI-S as mentioned above.
The first step is the same as in the SADI-S procedure, of creating the gastric sleeve. However, in the second step, the gastric sleeve is connected directly to the third section of the small intestine. This means that a larger portion of the small intestine is bypassed than in SADI-S. Therefore, less calories are absorbed, as the food spends an even shorter time moving through in the intestinal tract.
A revisional conversion bariatric surgery can take a variety of forms. Essentially, it is the name given to procedures that alter a previously performed bariatric surgery, including all of the aforementioned surgeries. For example, if a patient already had undergone Lap Band surgery, and then decided with their doctors that further help was needed in the weight loss journey, a revisional conversion bariatric procedure could be performed to remove the lap band and create a gastric sleeve or from a gastric sleeve to a gastric bypass.
In terms of the comparison between SADI-S and SASI-S, the main difference is wherein the small intestine is attached.
Where SADI-S and SASI-S would complete the sectioning of the stomach and adjustment of the intestines in one surgery, the revisional conversion bariatric surgery will be performed after the first step of creating a gastric sleeve, for example, has already been performed in a separate previous surgery and revision is done for reasons like weight gain and reflux.
