The first SIPS procedure in Cincinnati was performed at JourneyLite! SIPS stands for Stomach Intestinal Pylorus Sparing, and is a new procedure based on the traditional duodenal switch. The advantage of the SIPS is that the risk is lower as there is only one connection that needs to be made between the GI tract rather than two in the traditional DS, as seen below.
The SIPS procedure is also known as the Loop Duodenal Switch (LDS) and you can see why in the above image. The labels “A” and “C” in the image represent the connection between the duodenum, which is the first part of the small intestine, and a “loop” of the intestine much farther downstream. This results in much fewer calories being absorbed than the patient actually consumes. The term “pylorus sparing” refers to the fact that the pylorus remains intact, and the connection that is made (A to C) is between intestine and intestine rather than stomach and intestine as in a gastric bypass. This reduces the risk of dumping syndrome and ulcers.
Since the first part of a SIPS procedure is actually a gastric sleeve, it can be a great option for sleeve patients who still need to lose more weight. It is also the procedure of choice among many surgeons for high-BMI patients as many studies show duodenal switch offers the most weight loss, best resolution of diabetes, and lowest chance of long-term weight regain.
The SIPS procedure is done laparoscopically through 5 tiny incisions, takes about 90 minutes, and patients can typically go home in 24 hours. Back to work is generally 2 weeks for non-lifting jobs, and diet is advanced slowly over a period of 4 weeks to solid food.
As the SIPS procedure involves bypassing a significant amount of small intestine, patients must commit to life-long vitamin supplements and yearly lab work to check vitamin levels.
