Research and science

Our surgeons regularly publish scientific articles in the field of gastric reduction surgery

Gastric reduction surgery is a serious procedure. Therefore, it is always important to keep the science and measured short- and long-term effects of such an operation under review. Together with surgeons in the profession, we regularly participate in such studies. These studies contribute to the innovation of the profession.
