Watch this detailed video on Laparoscopic Sleeve Gastrectomy with Endoscopic Calibration. In this video, we explain the step-by-step surgical procedure, techniques, and tips for optimal patient outcomes. Perfect for surgeons, trainees, and anyone interested in advanced minimally invasive bariatric surgery.

Endoscopic calibration is associated with lower postoperative complications after laparoscopic sleeve gastrectomy. The use of the endoscope for the calibration of the gastric sleeve, instead of the standard use of the bougie, is a safe procedure and gives the surgeon a higher sense of security. The aim is to evaluate the effect of the use of endoscopic guidance on postoperative complications and mid-term results of the bariatric procedure. Gastrointestinal complication after sleeve gastrectomy surgery may be summarized as follow: acute bleeding and/or anemia, staple-line complications such as anastomotic leaks, fistulae, and strictures, erosion and slippage, bezoars, and choledocholithiasis. An endoscopy is the preferred strategy, unless there is a suspicion of leaks or fistulae, in which case preliminary contrast radiography may be more appropriate. Endoscopic treatment plays an important role in the management of a variety of staple-line complications during and even after surgery, such as stomal stenosis and anastomotic leaks. The intraoperative tightness check with blue dye and air insufflation through an orogastric tube in the bougie calibration group is done in all the patients. In the endoscopic calibration the check with blue dye is much better in all cases.

Obesity has become a global health challenge, with millions of people struggling with excess weight and its associated health risks, including diabetes, hypertension, and cardiovascular diseases. Among the various surgical options for weight loss, Laparoscopic Sleeve Gastrectomy (LSG) has emerged as a safe, effective, and minimally invasive procedure. When combined with endoscopic calibration, the surgery offers enhanced precision and improved patient outcomes.

What is Laparoscopic Sleeve Gastrectomy?

Laparoscopic Sleeve Gastrectomy is a bariatric surgery procedure in which approximately 75-80% of the stomach is surgically removed, leaving a slender, tube-shaped stomach or “sleeve.” This reduces the stomach’s capacity, limiting food intake and inducing a feeling of fullness faster.

The procedure also influences gut hormones, helping to reduce hunger, improve satiety, and enhance metabolic outcomes, which is particularly beneficial for patients with type 2 diabetes.

Role of Endoscopic Calibration

Endoscopic calibration involves the use of an endoscope during surgery to guide and measure the size of the gastric sleeve accurately. Traditionally, a bougie (a flexible tube) was used for calibration, but endoscopic guidance offers several advantages:

1. Precision: The endoscope allows the surgeon to visualize the gastric lumen directly, ensuring uniform sleeve size and preventing irregular narrowing.

2. Safety: Real-time endoscopic monitoring reduces the risk of leaks, strictures, or incomplete resections.

3. Enhanced Outcomes: Studies have shown that endoscopic calibration improves weight loss results and minimizes postoperative complications.

The Surgical Procedure

1. Preparation: The patient is placed under general anesthesia, and small incisions are made in the abdomen.

2. Insertion of Laparoscopic Instruments: A laparoscope and specialized surgical instruments are introduced through the incisions.

3. Stomach Resection: Using advanced stapling devices, the majority of the stomach is removed.

4. Endoscopic Calibration: An endoscope is inserted orally to ensure the newly created gastric sleeve is of the optimal size and shape. Adjustments are made if necessary.

5. Completion: The surgical area is inspected for leaks or bleeding. The instruments are removed, and incisions are closed.

Benefits of LSG with Endoscopic Calibration

• Minimally Invasive: Smaller incisions lead to less pain and faster recovery.

• Precise Sleeve Formation: Endoscopic calibration ensures uniformity and reduces complications.

• Effective Weight Loss: Patients typically lose 60-70% of excess body weight within 12–18 months.

• Improved Metabolic Health: Many patients experience remission of type 2 diabetes, hypertension, and other obesity-related conditions.

Recovery and Lifestyle Considerations

After surgery, patients are advised to follow a structured diet plan, gradually transitioning from liquids to soft foods and then solid meals. Regular follow-ups, exercise, and lifestyle modifications are crucial for long-term success.

Conclusion

Laparoscopic Sleeve Gastrectomy with Endoscopic Calibration represents a significant advancement in bariatric surgery. By combining minimally invasive techniques with real-time endoscopic monitoring, this procedure offers greater safety, precision, and efficacy for patients struggling with obesity. With proper medical guidance and lifestyle changes, patients can achieve sustainable weight loss and improved overall health.
