Research profile

Minimally invasive surgery is evolving rapidly, and the need for systematic development and evaluation of these methods is great. Our group focuses on research on the results of new minimally invasive surgical techniques in addition to development of new procedures. Most of the research is conducted in the field of HPB-surgery (diseases in liver, bile ducts and pancreas) and adrenal surgery.
