What is SADI-S?
SADI-S are the initials of the singleanastomosis duodeno-ileal bypass which stands for sleeve gastrectomy in English. In other words, here the duodenal ileum bypass surgery is performed with the gastric sleeve surgery.

What does SADI-S operation stand for?
The SADI-S operation involves, in addition to a pericardial tear operation, closing the duodenum immediately at the exit of the stenosis and connecting the small intestine section to the duodenum at the stomach exit.


The surgery is performed laparoscopically. First and foremost, the classic gastric sleeve surgery takes place. The stomach volume is reduced, however, it is still extended in comparison to a conventional gastric sleeve surgery.
In the next step, the duodenum is cut with special tools and closed to protect the pylorus (stomach outlet). From the junction of the small and large intestine, it is marked 250 (variable) and drawn to the duodenum to produce a duodenal small intestine anastomosis. For this reason, the food is taken from the common channel of about 2.5 meters. This reduces both the intake of food (sleeve) and the absorption of the ingested food (duodenal anastomosis).

What are the advantages of the SADI-S Method?

  • Follow-up diseases due to obesity such as diabetes, hyperlipidemia, sleep apnea and hypertension are eliminated
  • There is no danger of the dumping syndrome as the pilor is protected.
  • Since the pilor is protected, this method is more tolerated than the other methods

What are the disadvantages of the SADI-S Method?

  • Patients may need to take vitamin supplements (A, D, E, K, and minerals) throughout their lives.
  • Frequent control and follow-up examinations are necessary
  • Swelling of the gallbladder can occur and the risk of gallstones is higher than with other methods
  • Possible risks are the same as with the other methods: intestinal perforation, anastomosis
