What Are the Rewards and Risks of Sleeve Gastrectomy?

Sleeve gastrectomy is gastric sleeve surgery. Using advanced laparoscopic techniques, 75% -80% of the stomach reduces dramatically. The surgeon staples the extra portion of the stomach, and only a shape of a banana or tube-like stomach remains. Consequently, the patient’s stomach has a capacity of only 4 ounces—the surgery results in a cut down on food intake, which ultimately helps in weight loss. No surgical procedure is without any risk and complications. Likewise, laparoscopic sleeve gastrectomy also poses some difficulties. Hence, here we shall be discussing some risks of sleeve gastrectomy.

What is Gastric Sleeve Surgery?

  • The further steps is the analysis of stomach and division of the lateral blood vessels.
  • A Bougie tube is inserted inside the abdomen, which serves as a sizer for the expected stomach size.
  • The stomach is partitioned into two parts with the stapler.
  • Only 20% – 25% of the original stomach remains.

Moreover, the dramatic size reduction of the stomach results in decreased food intake and results in weight loss.

Leakage from the staple line is a severe complication & risk of sleeve gastrectomy. The reported average blood leakage from the staples is 2.8%. However, if it increases due to improper treatment, it may lead to abscesses, sepsis, fistulas, cutaneous, in severe cases organ failure, and death.
