In duodenal switch, the surgeon removes 80% of the stomach, similar to the gastric sleeve procedure. It bypasses a portion of the small intestine, like the gastric bypass. However, rather than attaching the small stomach to the small intestine -- which is done with gastric bypass -- the stomach is connected to the duodenum, the first portion of the small intestine.
Minimally Invasive Duodenal Switch
Your surgeon may use different devices, such as magnets or robotic surgery, to reduce the number of incisions needed to perform duodenal switch. This minimally invasive surgery approach:
- Shortens your hospital stay (typically one to two nights)
- Leaves small scars
- Helps you recover quickly and with less pain
Less Invasive Version Being Studied
We completed enrollment in a multi-center trial to evaluate a less invasive version of the duodenal switch, known as the loop duodenal switch. It is also called Single Intestinal Pyloric Sparing Surgery (SIPS) and Single-Anastomosis Duodenal Switch (SADS). The duodenal switch intersects the small intestine at two points. The loop duodenal cuts at only one, which creates the loop for which the procedure is named. We continue to study this modification. This procedure is not covered by insurance.
