How many anastomotic sites are there in SADI-S / SIPPS procedures?

In SADI-S (Single Anastomosis Duodeno-ileal Switch) and SIPPS (Single Incision Pancreaticoduodenal Switch) procedures, there is typically one anastomosis site where the intestine is reconnected. This technique simplifies the surgical approach compared to other bariatric surgeries, reducing complexity and potential complications associated with multiple connections.

The rationale behind having a single anastomosis is to combine the advantages of duodenal switch surgery—like significant weight loss and metabolic improvements—while minimizing the risks associated with additional anastomoses. Therefore, focusing on just one anastomotic site allows for a more streamlined procedure.

Understanding the anatomy and physiology involved, as well as the implications of the procedure on nutrition and absorption, further supports why there is indeed only one primary site for anastomosis in these types of surgeries.
