SASI (Single Anastomosis Sleeve Ileal Bypass) — Advanced Bariatric Surgery (Laparoscopic)
SASI is a modern bariatric procedure that combines a sleeve gastrectomy with a single intestinal connection to enhance weight loss and improve metabolic health. It supports both restriction (smaller stomach) and metabolic/absorptive change (partial diversion of food to the distal small intestine), which can help with long-term results.

What is SASI?
During SASI, the surgeon:
- Performs a Sleeve Gastrectomy (removes part of the stomach to create a narrow sleeve)
- Creates one anastomosis (single connection) between the sleeve and a part of the ileum (the last portion of the small intestine)
This means food can travel through:
- The normal route (stomach → small intestine), and
- A shortcut route (stomach sleeve → ileum)
Result: improved satiety, hormonal changes, and stronger metabolic effects for many patients.
Who May Benefit from SASI?
You may be a candidate if:
- BMI ≥ 40, or
- BMI ≥ 35 with conditions like type 2 diabetes, hypertension, fatty liver, sleep apnea
- You need a procedure with strong metabolic impact
- You can commit to nutrition guidelines, supplements, and long-term follow-up
The final decision depends on your medical evaluation and surgeon’s assessment.

Key Benefits
- Strong weight loss potential with powerful metabolic effects
- Often excellent improvement in type 2 diabetes and insulin resistance
- Single anastomosis (one connection) compared to traditional bypass options
- Laparoscopic technique: smaller scars, faster recovery
- Keeps a physiologic route for part of the food passage (two pathways)
Risks & Important Considerations
Possible risks include:
- Vitamin/mineral deficiencies without proper supplementation
- Diarrhea / frequent stools or gas/bloating in some patients (often improves with diet adjustment)
- Reflux in certain cases
- Ulcers, narrowing, leakage, internal complications (rare)
- General surgical risks: bleeding, infection, blood clots (rare)
Key point: outcomes and side effects depend heavily on diet quality, follow-up, and supplements.
Pre-Op Preparation
Usually includes:
- Full lab work + medical assessment
- Sometimes an upper endoscopy (based on symptoms/history)
- Pre-op diet plan as advised
- Stop smoking and optimize medical conditions (sugar/pressure)
- Education on post-op nutrition phases and supplements

Recovery & Aftercare
- Short hospital stay in many cases
- Early mobilization and hydration focus
- Diet progression: clear liquids → full liquids → purées → soft foods → regular
- Routine supplements guided by lab monitoring (B12, iron, calcium, vitamin D, etc.)
- Scheduled follow-ups to track weight loss, nutrition, and metabolic improvement

FAQ ideas:
Sleeve is restriction only. SASI adds an intestinal bypass connection, which may increase metabolic and weight-loss effects.
Some surgeons consider it more modifiable than certain bypass procedures, but it’s still a major operation and decisions are case-specific.
Yes. Long-term vitamins and regular blood tests are essential.
Often within 1–2 weeks, depending on your recovery and job type.
