Gastric Sleeve Surgery ( Sleeve Gastrectomy ) in India

Definition

Gastric sleeve surgery, also known as sleeve gastrectomy, is a bariatric (weight-loss) surgical procedure in which approximately 75–80% of the stomach is removed, leaving a narrow, tube-shaped stomach resembling a sleeve. It helps patients lose weight by reducing stomach capacity and altering appetite-related hormones.

Indications

• Obesity requiring surgical treatment.

• Difficulty achieving sufficient weight loss through nonsurgical methods.

• Type 2 diabetes associated with obesity.

• High blood pressure related to obesity.

• Obstructive sleep apnea.

• Other obesity-related health conditions.

Eligibility is determined by a bariatric specialist based on BMI, medical history, and applicable clinical guidelines.

Procedure

1. The patient is placed under general anesthesia.

2. Several small incisions are made in the abdomen.

3. A laparoscope and surgical instruments are inserted.

4. A surgical tube (bougie) may be used to guide the size of the new stomach.

5. Approximately 75–80% of the stomach is removed using surgical stapling devices.

6. The remaining stomach forms a narrow, sleeve-shaped tube.

7. The staple line is assessed for bleeding or leakage.

8. The incisions are closed.

Mechanism of action

• Restriction: Reduces the amount of food the stomach can hold.

• Hormonal changes: Reduces production of ghrelin, a hormone involved in hunger.

• Early satiety: Helps the patient feel full after eating smaller portions.

• Metabolic improvement: Can improve blood glucose control and other obesity-related conditions.

Advantages

• Significant weight loss for many patients.

• Improvement in type 2 diabetes and high blood pressure.

• No intestinal bypass is required.

• No implanted gastric band or device is needed.

• Can improve mobility and quality of life.

Complications

Early complications

• Bleeding.

• Infection.

• Leakage from the stomach staple line.

• Blood clots.

• Anesthetic complications.

Long-term complications

• Gastroesophageal reflux disease (GERD) or worsening acid reflux.

• Vitamin and mineral deficiencies.

• Narrowing of the stomach sleeve.

• Vomiting or food intolerance.
