Gastric fundus / Fundus

The fundus is the upper part ("dome") of the stomach. In a surgical sleeve gastrectomy, it is typically completely removed. In the endoscopic technique (ESG), we avoid touching the fundus and leave it intact.

‍Why? The wall of the fundus is very thin and rich in blood vessels, and suturing it may be dangerous. Instead, we focus on narrowing the body of the stomach beneath it.
This allows us to achieve effective weight loss while maintaining maximal safety and preventing complications such as bleeding or impaired blood supply to the stomach.
