Bariatric Gastric sleeve surgery: Is it a mandate to remove 80 percent of your stomach?

The advantage that I can take away the percentage that I think necessary we can reach an agreement on how much the patient wants to remove, it is not a rule that I should remove 80%

It's completely understandable to feel nervous about the gastric sleeve procedure, particularly due to its irreversible nature and the significant removal of the stomach. In a typical gastric sleeve surgery, about 75-80% of the stomach is removed. This is a standard approach based on extensive research and clinical experience, as removing this portion of the stomach effectively limits its capacity and significantly reduces hunger. It also improves metabolic functions, contributing to weight loss and overall health benefits.
Requesting the removal of only 50% of your stomach is technically possible, but it is not a common practice. A smaller portion of stomach removal generally results in a larger stomach pouch, which could reduce the effectiveness of the procedure. A larger stomach may mean you retain more of your ability to eat larger portions, which can slow down weight loss or even increase the likelihood of regaining weight in the future. The standard removal amount, while seemingly drastic, is intended to give you the best chance for long-term success by ensuring the stomach is sufficiently restricted.
Additionally, the procedure uses a specific technique and tools, such as a bougie, to guide the size of the remaining stomach. The smaller the bougie used, the tighter and smaller the remaining stomach will be. If you are concerned about the size of the stomach being too small for your comfort, you can discuss the possibility of using a larger bougie size to allow for a slightly larger stomach. However, this may slightly reduce the overall effectiveness in terms of weight loss and appetite control.
It is essential to communicate openly with your surgeon about your concerns. They can provide a thorough explanation of the potential risks and benefits of different approaches, taking your health and comfort into consideration.

Removing 50% of the stomach is not good when doing surgery as the fundus should be removed. If you remove only 50% the regain of weight will be after 4 months. So 80% of the stomach should be removed to obtain ideal results. In fact, after passing one year of the operation, the stomach dilates somehow again so it will not be the same 20%you came out from the procedure withSo no need to worry

If you want to remove only 50% of your stomach, we can discuss it with you in your surgical plan and seek the healthiest approach. I hope you get the results you are expecting. You'll do great! A.L

The amount of stomach to remove for a sleeve gastrectomy has been extensively studied. Basically, surgeons want to balance effectiveness of the operation versus associated risks. We usually talk in terms of "Bougie Size" when referring to sleeve size. This relates to the tube-sizer that is passed into the stomach to guide the staple line formation. Most surgeons use a Bougie size of approximately 40 French for a sleeve gastrectomy. This correlates to the 80% of stomach removal.
