Sasi Procedure in Turkey: Complete Guide to Metabolic & Weight Loss Surgery

Obesity is a complex, chronic medical condition characterized by excessive adipose tissue accumulation that poses severe risks to physical, metabolic, and psychological well-being. Individuals struggling with severe obesity frequently face co-morbidities such as type 2 diabetes, arterial hypertension, obstructive sleep apnea, hyperlipidemia, and joint degeneration. When non-surgical interventions like dietary restrictions, physical exercise, and pharmacotherapy fail to produce sustainable weight loss, advanced metabolic and bariatric surgery offers a proven clinical pathway toward long-term health restoration.

Among modern surgical breakthroughs, the sasi procedure (Single Anastomosis Stomach-Ileal Bypass) has emerged as one of the most effective and metabolically favorable bariatric operations worldwide. Combining the mechanical restriction of a sleeve gastrectomy with the hormonal and malabsorptive benefits of an ileal bypass, the sasi procedure offers exceptional weight loss results and high rates of type 2 diabetes remission. Turkey, recognized globally for its high-caliber medical facilities and board-certified bariatric surgeons, serves as a premier destination for international patients seeking state-of-the-art metabolic surgery.

Procedure & Treatment Overview

The sasi procedure (Single Anastomosis Stomach-Ileal Bypass) is an innovative hybrid bariatric technique developed to improve upon traditional procedures such as the Roux-en-Y gastric bypass and standard vertical sleeve gastrectomy. It operates on two distinct clinical principles: anatomical restriction and metabolic hormonal modulation.

During the operation, the surgeon first performs a longitudinal sleeve gastrectomy, removing approximately 70% to 80% of the stomach along the greater curvature. This reduces the stomach capacity significantly and drastically decreases the production of Ghrelin, the primary hunger-stimulating hormone. Next, a single loop of the distal small intestine (the ileum) is elevated and connected directly to the lower part of the newly created gastric sleeve (antrum). This creates a single anastomosis loop.

Because the natural gastric outlet (the pylorus) remains fully intact and operational, food digested after a sasi procedure follows two pathways: approximately 30% to 40% passes through the normal duodenum and upper intestine (ensuring minimal nutrient and vitamin malabsorption), while 60% to 70% flows directly into the lower ileum. This rapid transit of nutrients to the distal intestine stimulates the immediate release of gut hormones such as GLP-1 (Glucagon-Like Peptide-1) and PYY (Peptide YY), suppressing appetite and restoring insulin sensitivity.

Ideal Candidates & Medical Assessment

Determining candidacy for the sasi procedure requires a thorough pre-operative clinical evaluation conducted by a multidisciplinary team, including bariatric surgeons, endocrinologists, nutritionists, and anesthesiologists. Ideal candidates generally meet the following criteria:

  • Body Mass Index (BMI): A BMI of 35 kg/m² or higher, or a BMI between 30 and 34.9 kg/m² accompanied by severe metabolic complications such as poorly controlled type 2 diabetes, metabolic syndrome, or severe hypertension.
  • Uncontrolled Type 2 Diabetes: Patients suffering from insulin resistance or long-standing type 2 diabetes who desire significant glycemic control or complete metabolic remission.
  • Failed Non-Surgical Weight Loss Attempts: Individuals who have attempted structured exercise regimes, medical diets, and lifestyle modifications without achieving lasting clinical results.
  • Commitment to Lifestyle Modifications: Patients willing to adhere to post-operative dietary progression, nutritional supplementation protocols, and routine follow-up consultations.
  • Overall Surgical Fitness: Psychological stability and medical clearance to undergo general anesthesia and laparoscopic abdominal surgery.

Modern Surgical Techniques & Technologies

At Health Beauty Turkey, the sasi procedure is executed using advanced minimally invasive laparoscopic techniques. Minimally invasive surgery reduces tissue trauma, minimizes post-operative pain, limits scarring, and significantly shortens hospital stays compared to open abdominal procedures.

Key surgical advancements utilized during the operation include:

  • High-Definition 3D/4D Laparoscopy: Provides surgeons with enhanced spatial depth and magnified visualization of major abdominal vessels and visceral tissues.
  • Tri-Staple Endoscopic Technology: Medical-grade robotic and motorized staplers ensure tissue-specific compression and leak-proof vascular staple lines along the stomach curvature and anastomosis site.
  • Intraoperative Leak Testing: Dual-check systems utilizing methylene blue dye or pneumatic air-leak testing guarantee complete integrity of the gastric line and intestinal join prior to finalizing the procedure.
  • Enhanced Recovery After Surgery (ERAS) Protocols: Pre- and post-operative care pathways designed to reduce physiological stress, encourage early mobilization within hours of surgery, and minimize opioid dependence.

Step-by-Step Procedure Process

Understanding the clinical steps of the sasi procedure helps patients approach their treatment journey with confidence and peace of mind:

1. Pre-Operative Preparation & Assessment

Upon arrival, patients undergo comprehensive diagnostic evaluations including blood chemistry, liver function tests, HbA1c, chest X-rays, electrocardiograms (ECG), abdominal ultrasound, and gastroscopy to confirm gastric mucosal health.

2. Administration of Anesthesia

The patient is placed under general anesthesia with continuous endotracheal monitoring overseen by a senior anesthesiologist.

3. Laparoscopic Access

Four to five minor keyhole incisions (5mm to 12mm) are made across the upper abdomen. A pneumoperitoneum is established using carbon dioxide gas to create a clear surgical field.

4. Vertical Sleeve Gastrectomy Phase

A calibration bougie catheter is inserted into the stomach. The surgeon uses endoscopic surgical staplers to divide and resect the outer 75% of the stomach, converting it into a narrow tube or sleeve.

5. Single Anastomosis Construction

The surgeon measures approximately 250 to 300 centimeters of the lower small intestine (ileum) from the ileocecal valve. This loop is elevated and connected directly to the lower portion of the gastric sleeve (antrum) using an end-to-side stapled anastomosis.

6. Leak Test & Surgical Closure

An intraoperative leak test is performed. Once verified, the trocars are removed, the muscle layers are approximated, and keyhole incisions are closed using absorbable subcuticular sutures.

Recovery Timeline, Aftercare & Expected Results

Post-operative recovery after a sasi procedure is structured systematically to optimize healing and ensure adequate fluid and metabolic balance.

  • Days 1–2 (Hospital Phase): Immediate post-operative monitoring, early ambulation, and intravenous hydration. A clear liquid diet (water, clear broth) is initiated after passing clinical checks.
  • Weeks 1–2 (Full Liquid Diet): Transition to protein-enriched liquids, strain soups, and liquid vitamins. Normal non-strenuous daily activities can be resumed.
  • Weeks 3–4 (Pureed Diet): Soft, pureed foods rich in lean proteins and low in carbohydrates are introduced gradually.
  • Month 2 and Beyond (Solid Foods): Reintroduction of solid high-protein foods, masticating thoroughly and avoiding simultaneous fluid consumption during meals.

Patients typically achieve rapid weight loss in the first 6 months, losing up to 50% of their excess weight, with total excess weight loss reaching 70% to 85% at 12 to 18 months. Crucially, the preservation of the pylorus minimizes the incidence of severe nutritional deficiencies and dumping syndrome compared to traditional gastric bypass operations.

Frequently Asked Questions (FAQ)

What is the main advantage of the sasi procedure over standard gastric sleeve or bypass?

The sasi procedure combines the benefits of both operations. It reduces hunger via gastric sleeve resection while boosting metabolic gut hormones through a single intestinal connection. Because the pylorus valve is preserved, food still passes through the normal duodenum, significantly reducing the risk of severe vitamin deficiencies associated with complete bypasses.

How long will I need to stay in Turkey for the sasi procedure?

Patients typically stay in Turkey for 5 days. This includes pre-operative diagnostic testing, 2 to 3 nights of inpatient hospital care under direct surgeon supervision, and a final evaluation before medical clearance for travel home.

Is the sasi procedure effective for curing Type 2 Diabetes?

Yes. By enabling food to reach the distal ileum rapidly, the sasi procedure triggers immediate secretion of GLP-1, a hormone that dramatically increases pancreatic insulin sensitivity. Clinical studies indicate diabetes remission rates between 85% and 90% shortly after surgery.

What nutritional supplements will I need after surgery?

While the sasi procedure carries a lower risk of malabsorption than traditional gastric bypass, patients are advised to take daily bariatric multivitamins, calcium, vitamin D, and iron supplements, guided by routine periodic blood tests monitored by our nutrition team.
