Stomach Intestinal Pylorus-Sparing (SIPS) surgery is a type of weight-loss surgery.

It was developed in 2013 by two U.S. surgeons, Daniel Cottam[1] from Utah and Mitchell S. Roslin from New York.

[2] It is substantively the same procedure as the SADI surgery.

SIPS surgery is a modified version of duodenal switch (DS) surgery.

The SIPS surgery involves the creation of a 300-cm common channel with a single-anastomosis duodenal enterostomy.
