SADI-S Surgery

At Nacogdoches Medical Partners, we are committed to providing effective solutions for individuals struggling with obesity and seeking long-term weight loss. One of the advanced procedures we offer is the SADI-S surgery. This weight loss surgery combines the benefits of two established bariatric procedures to help patients achieve significant and sustainable results. 

What Is SADI-S Surgery?

SADI-S, or Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy, is a bariatric surgery that merges two well-established weight loss procedures: the sleeve gastrectomy and a modified duodenal switch. This combination aims to restrict food intake and reduce calorie absorption, addressing obesity from two critical angles.

  • Sleeve gastrectomy: The first part of the surgery involves removing approximately 80% of the stomach, transforming it into a slender "sleeve." This gastric sleeve operation limits the amount of food you can consume, promoting early satiety and reducing calorie intake. The sleeve gastrectomy also impacts hunger hormones, which can help decrease appetite.
  • Duodeno-ileal bypass: The second part reroutes the small intestine. The surgeon connects the beginning of the duodenum to a loop of the ileum (the last part of the small intestine). This single anastomosis (connection) bypasses a significant portion of the small intestine, reducing the absorption of calories and nutrients.

This procedure is sometimes referred to as the loop DS surgery because it involves creating a loop in the intestinal tract. The SADI-S bariatric surgery is designed to offer the substantial weight loss associated with a traditional duodenal switch but with a simpler surgical process and potentially fewer complications.

How Is SADI-S Surgery Performed?

The SADI-S operation is performed using minimally invasive laparoscopic techniques, which involve small incisions and specialized instruments. This approach generally results in less postoperative pain, reduced scarring and quicker recovery times compared to open surgery.

SADI-S Procedure:

  1. Anesthesia administration: You'll receive general anesthesia to ensure comfort and safety throughout the surgery.
  2. Insertion of laparoscopic instruments: The surgeon makes several small incisions in the abdomen to insert a laparoscope (a tiny camera) and surgical instruments.
  3. Sleeve gastrectomy:
    • A large portion of the stomach (about 80%) is removed, leaving a tube-shaped "sleeve."
    • This gastric sleeve gastrectomy restricts food intake and affects hormones related to hunger and satiety.
  4. Duodeno-ileal bypass:
    • The duodenum is divided just past the pylorus (the valve controlling food release from the stomach to the small intestine).
    • A loop of the ileum is brought up and connected to the duodenum, creating a single anastomosis.
    • This bypasses a substantial length of the small intestine, reducing calorie and nutrient absorption.
  5. Closure and recovery:
    • The surgeon checks for leaks or obstructions.
    • Instruments are removed, and incisions are closed with sutures or staples.

The entire SADI-S procedure typically takes between two to three hours, depending on individual circumstances.

Who Is a Good Candidate for SADI-S Surgery?

Determining candidacy for SADI-S weight loss surgery involves a comprehensive evaluation by a healthcare professional specializing in bariatric procedures. Generally, suitable candidates include individuals who:

  • Have a high body mass index (BMI):
    • A BMI of 40 or higher (extreme obesity).
    • A BMI of 35 or higher with serious obesity-related health conditions, such as Type 2 diabetes, hypertension or obstructive sleep apnea.
  • Failed previous weight loss attempts:
    • Those who have not achieved significant weight loss through diet, exercise, or medication.
    • Individuals who have regained weight after previous bariatric procedures like the gastric sleeve.

SADI-S surgery may be particularly beneficial for patients with Type 2 diabetes due to its impact on hormonal pathways affecting insulin sensitivity.

What Are SADI-S Surgery Side Effects?

While SADI-S surgery can offer significant benefits, it's important to be aware of potential side effects and risks associated with the procedure.

Common side effects:

  • Nutritional deficiencies:
    • Due to decreased absorption of nutrients, deficiencies in vitamins and minerals such as iron, calcium, vitamin D, vitamin B12, and protein can occur.
    • Lifelong supplementation and regular monitoring are necessary.
  • Gastrointestinal issues:
    • Patients may experience diarrhea, bloating, or foul-smelling stools (steatorrhea) as the body adjusts to the changes in digestion.
    • Dumping Syndrome: Rapid gastric emptying can lead to symptoms like nausea, vomiting, dizziness, sweating, and diarrhea after eating.
  • Gallstones:
    • Rapid weight loss can increase the risk of gallstone formation.

Potential risks:

  • Surgical complications:
    • Infection, bleeding or adverse reactions to anesthesia.
    • Anastomotic leaks where the intestines are reconnected.
  • Malnutrition:
    • Severe deficiencies can lead to anemia, osteoporosis, or neurological issues if not properly managed.
  • Bowel obstruction:
    • Scar tissue can lead to blockages in the intestines.

How Long Is the Recovery Time for SADI-S Surgery?

Recovery time varies by individual but generally follows this timeline:

  • Hospital stay: Most patients stay in the hospital for two to three days post-surgery.
  • Initial recovery: Within two weeks, you can typically resume light activities.
  • Full recovery: Most patients return to normal activities within four to six weeks.

During recovery, you'll follow a graduated diet plan, starting with liquids and gradually introducing solid foods.

Maintain regular follow-up appointments with your healthcare provider to monitor for these side effects. Dietary adherence and compliance with vitamin and mineral supplementation can significantly reduce the risk of complications.
