What is a characteristic of SADI-S?

The characteristic of SADI-S (Single Anastomosis Duodeno-ileal Bypass with Sleeve Gastrectomy) that is correctly identified is its single anastomosis approach. In SADI-S, a single connection or anastomosis is created between the sleeve stomach and the small intestine, which simplifies the surgical process compared to traditional bariatric surgeries that may involve multiple anastomoses, such as Roux-en-Y gastric bypass.

This single anastomosis technique has several advantages, including reduced operative time, minimized complication rates associated with multiple connections, and a streamlined postoperative recovery process. The design of SADI-S facilitates effective weight loss by reducing both the functional stomach size and altering the digestive process, while still maintaining some normal gastrointestinal functionality.

In contrast, the other options portray different characteristics that do not align with the nature of SADI-S. For instance, the method does involve bypassing parts of the intestine for effective weight loss, thus not reducing stomach size without bypass. While postoperative monitoring is necessary for any bariatric procedure, SADI-S does not inherently require extensive monitoring beyond standard care for surgical patients. Finally, SADI-S is a surgical intervention, not a non-surgical method based on lifestyle changes alone.
