Single-Anastomosis Sleeve Ileal Bypass
A Newer Bariatric Procedure With Powerful Results
SASI combines a gastric sleeve with a single loop connection to the ileum. It delivers higher weight loss than sleeve alone and excellent type-2 diabetes remission, while preserving normal food passage through the duodenum — fewer nutritional deficiencies than a full duodenal switch.
Quick Take · 30 seconds
- Weight loss: 70–80% EWL at 3–5 years
- Diabetes: ~80% type-2 diabetes remission
- Nutrition: Fewer deficiencies than SADI-S / DS
- Best for: BMI 40–60 with metabolic disease
How SASI Surgery Works
Two components working together for weight loss + metabolic control
SASI vs Sleeve vs SADI-S
| Sleeve (VSG) | SASI | SADI-S | |
|---|---|---|---|
| EWL (5-year) | 55–65% | 70–80% | 75–85% |
| Diabetes remission | ~60% | ~80% | ~85% |
| Vitamin deficiencies | Minimal | Low-moderate | High (lifelong) |
| Food passes duodenum | Yes | Yes (partial) | No (bypassed) |
| Reversibility | No | Partial | No |
| Tijuana cost (from) | $4,500 | $6,900 | $6,900 |
EWL = Excess Weight Loss. Ranges based on 3–5 year peer-reviewed data.

Why Patients Choose SASI
Superior Weight Loss
10+ points more EWL than sleeve alone at 5 years.
Diabetes Powerhouse
GLP-1 response from ileal loop drives ~80% T2D remission.
Better Nutrition
Food still passes duodenum — fewer deficiencies than SADI-S/DS.
Partial Reversibility
The ileal loop can be reversed — unlike sleeve or SADI-S.
Revision-Friendly
Convert a failed sleeve without going straight to SADI-S/DS.

SASI Surgery FAQs
Is SASI safer than SADI-S or duodenal switch?
Yes, SASI carries a lower nutritional risk than SADI-S or DS because food still passes through the duodenum. Vitamin, mineral, and protein deficiencies are less common, and lifelong supplementation is lighter. Surgical complication rates are similar to SADI-S.
Can SASI be reversed?
Partially. The ileal loop connection can be disconnected in most cases, returning function to a sleeve-only state. This is a major advantage over sleeve or SADI-S, which are considered permanent.
Do you offer SASI as revision after a failed sleeve?
Yes. SASI is one of the best revision paths from a failed gastric sleeve because it preserves the existing sleeve pouch and simply adds the ileal loop — less complex than converting to SADI-S or DS.
How much does SASI cost in Tijuana?
From $6,900 USD cash all-inclusive at ALO Bariatrics — same price as SADI-S given comparable operating room time. Includes hospital, surgeon, anesthesia, 2 nights, pre-op labs. Final quote depends on BMI, comorbidities, and hospital.
Will I still need vitamins after SASI?
Yes, but the protocol is lighter than SADI-S or DS: a daily multivitamin, B12 (oral or injection), iron, and vitamin D are typical. Annual labs check nutritional status. Because food still passes the duodenum, calcium and fat-soluble vitamin absorption is better preserved.
