A comprehensive guide to SADI-S/SIPS weight loss surgical procedure

SADI-S (Single Anastomosis Duodenal–Ileal Bypass with Sleeve Gastrectomy) or SIPS (Stomach Intestinal Pylorus Sparing) surgery is a relatively new option in the realm of weight loss surgical procedures. Nonetheless, it presents an intriguing alternative for individuals struggling with morbid obesity, demonstrating encouraging initial outcomes. This procedure facilitates long-term weight loss by curtailing food intake and inducing neuroendocrine modifications. Allow me to elaborate further on the various aspects of SADI-S bariatric surgery.

SADI-S procedure

The SADI-S procedure closely resembles the duodenal switch operation, with the primary distinction being the execution of a single loop Anastomosis of the small intestine rather than two. The surgical intervention entails the creation of a sleeve, akin to sleeve gastrectomy, albeit with a slightly larger dimension. Furthermore, the surgeon bypasses the proximal half of the small intestine, approximately 300 cm from the ileocecal valve, and meticulously sutures the initial segment of the duodenum beyond the pylorus to the designated bypass point. Post-operatively, the stomach's capacity is effectively restricted to roughly 120 ml, resulting in a sense of satiety after consuming a mere 3 to 4 ounces of sustenance.

How SADI-S procedure works?

The SADI-S weight loss surgical procedure preserves crucial functional components of the stomach, including the antrum and pylorus. This technique allows patients to consume smaller portions of their preferred foods and feel satiated without experiencing “dumping” syndrome, unlike other restrictive procedures that impose strict dietary limitations. Additionally, surgeons modify the intestinal pathway to trigger neuroendocrine reflexes, resulting in automatic weight loss. Post-surgery, the upper section of the small intestine solely transports digestive fluids, such as bile and pancreatic juices. This shortened digestive tract contributes to weight loss by reducing calorie absorption.

Benefits of SADI-S

SADI-S weight loss surgery effectively addresses various complications commonly experienced by patients who have undergone gastric bypass surgery, such as:

• Marginal ulcers at the upper joint
• Dumping syndrome
• Unpredictable fluctuations in blood glucose levels
• Severe intolerance to certain food items

Post-surgery experience

On average, patients who undergo SADI-S can expect a weight loss comparable to that achieved through duodenal switch surgery, surpassing the results of gastric bypass or gastric sleeve procedures. However, SADI-S induces weight loss at a slower, more gradual pace. Notably, SADI-S exhibits a more favourable complication profile and superior initial outcomes compared to other weight loss surgeries. Consequently, this surgical intervention is particularly well-suited for patients who have regained weight after sleeve gastrectomy, as well as individuals with morbid obesity accompanied by severe metabolic syndrome.

Wrapping up

SADI-S weight loss surgery enables patients to achieve substantial weight reduction within a shorter timeframe following the procedure. Notably, patients are spared from experiencing dumping syndrome, ulcers, and other common adverse effects associated with bypass surgery.
