What is subtotal gastrectomy?

Subtotal gastrectomy is a surgical procedure that involves the removal of a significant portion of the stomach, typically to treat conditions such as stomach cancer, ulcers, or severe obesity. The remaining stomach is then reconnected to the small intestine to allow for digestion. This surgery can lead to changes in digestion and nutrient absorption, requiring patients to adjust their eating habits postoperatively. It is considered a more conservative approach than a total gastrectomy, where the entire stomach is removed.
