    What Types of Surgical Methods Are Used?

    • Sleeve Gastrectomy: Approximately 75–80% of the stomach is removed to reduce its volume.

    • Gastric Bypass: Both the stomach size is reduced and part of the small intestine is bypassed.

    • Other options such as Mini Gastric Bypass and Duodenal Switch may be considered for selected patients.

    Is Weight Regain Possible After Surgery?

    When Is Surgery Performed in Stomach Cancer?

    If the tumor is localized and has not spread, surgery is usually the first-line treatment. Depending on the extent, partial (subtotal gastrectomy) or total removal of the stomach (total gastrectomy) may be performed. Lymph nodes surrounding the stomach may also be removed if necessary.

    How Do Patients Eat After Total Gastrectomy?
