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 , pancreas) and adrenal surgery. A central project for our group is the Oslo CoMet-study (Oslo randomized laparoscopic vs open liverresection for colorectal liver metastasis – study). In addition to the evaluation of surgical and oncological results, several translational studies are performed, such as biobanking of tumor tissue, studies on the inflammatory response, health economy evaluation and pain/quality of life studies. New database software has been developed .
The research group also does research on MRI-guided High Intensity Focused Ultrasound (HIFU) of lesions in liver and prostate. Together with the University of Gothenburg, we research novel biomaterials in implants. A large international survey of laparoscopic pancreas surgery is currently initiated. Research on imaging of liver tumours (CT, MRI, PET-CT) is conducted with other research groups at the IVS and OUS. In a joint project, a method for automatic segmentation of liver anatomy including tumours is developed. The final goal is to create an interactive map for liver surgeons that will greatly ease both planning and the actual surgery. The group has a large international network of collaborators.

  • RCT of open and laparoscopic liver resection (The CoMet study)
  • Minimally invasive techniques in treatment of lesions in abdominal endocrine organs
  • Percutaneous access and connection to visceral organs using biomaterial implants.
  • Laparoscopic distal pancreatectomy for cancer, an international multicenter study
