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.

Ongoing Projects

  • The Oslo CoMet-study (Oslo randomized laparoscopic vs open liver resection for colorectal liver metastasis – study). Funding: HSØ
  • In addition to the evaluation of surgical and oncological results, several translational studies are performed, such as bio banking of tumour tissue, studies on the inflammatory response, health economy evaluation and pain/quality of life studies.
  • Multicentre studies on laparoscopic liver surgery
  • Research on pancreatic cancer: Examining the Role of Laparoscopic Distal Pancreatectomy in the Treatment of Pancreatic Cancer: From a Consensus Study to Randomized Controlled Trials. The main aim is to assess the oncologic outcomes of Laparoscopic Distal Pancreatectomy (LDP) in patients with Pancreatic Distal Adeno- Carcinoma, determine the prognostic factors and provide justified recommendations for its use. Funding: Kvote programmet UiO
  • The research group also does research on MRI-guided High Intensity Focused Ultrasound (HIFU) of lesions in liver and prostate. Funding: Kreftforeningen
  • Together with the University of Gothenburg, we do research on biomaterials in implants.
  • 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 tumors is developed. The final goal is to create an interactive map for liver surgeons that will greatly ease both planning and the actual surgery.

High Intensity Focused Ultrasound (HIFU)-therapy is completely non-invasive as the ultrasound energy is delivered outside the body, but focused in defined areas in an organ. MR provides three-dimensional treatment planning and real-time temperature feedback. Integrating HIFU in MR-scanners melds the technology for visualization and treatment, optimize the procedure and increase the therapeutic potential of HIFU treatment. The 3 T MR at the Intervention Centre has integrated HIFU equipment as part of a research agreement with Philips Medical Systems. Focus has been on both basic and clinical research projects.

Ongoing Projects:

  • MR guided HIFU in the treatment of uterine fibroids
  • Basic research on MR guided HIFU of liver
  • Basic research on MR guided HIFU of prostate
  • Collaborations:

A trend in cardiovascular therapies involves development of minimal invasive surgical techniques for valve repair and treatment of severe heart failure by biventricular pacing. Even though a method can be classified as minimal invasive, the procedural risks still may be high, as demonstrated by treatment of severe aortic stenosis by catheter technique (TAVI) instead of open chest surgery. Another trend in severe heart failure treatment is implantation of mechanical pumps, as either bridge to transplantation or as destination therapy as an alternative to heart transplantation. In contrast to the other therapies, implantation of a mechanical pump is a highly invasive procedure and justifies more invasive monitoring of the patient. In both cases, assessment of cardiovascular status is equally important, but requires different approaches which need to be adapted to the risks and invasiveness of the procedures. New methods for cardiovascular monitoring in the operative setting may also be used to guide and optimize treatment in hemodynamically compromised patients in the intensive care unit, such as in patients with septic or cardiogenic shock, and patients treated with therapeutic hypothermia after cardiac arrest.

Main aims

  • Develop and test new technologies in cardiovascular monitoring
  • Cardiovascular response to new cardiovascular therapies
  • Myocardial function in therapeutic hypothermia and severe sepsis

This includes evaluating hemodynamic responses of 1) new cardiovascular image guided procedures, 2) ECMO strategies, 3) treatment for end stage heart failure with ventricular assist devices (VAD). Technologies under investigation for cardiac function monitoring include implantable 3D accelerometers, gyro, magnetometer, miniaturized ultrasound sensors, biosensors and radar. The sensors are tested in both clinical and experimental models in cooperation with other research groups at The Intervention Centre, departments at OUS and external institutions.

Ongoing research projects

  • TAVI: is myocardial reserve related to long term outcome?
  • Accelerometer for detection of thromboembolic events in LVAD
  • Accelerometer/gyro/magnetometer for monitoring changes in right and left ventricular load and detection of graded myocardial ischemia.
  • Can betablockers improve survival and cardiovascular function after cardiac arrest: an experimental ECMO study
  • Left and right ventricular dysfunction in severe sepsis; the effect of pulmonary hypertension and interventricular septal shift
  • Myocardial effects of therapeutic hypothermia in cardiac surgery
  • Effects of epinephrine and betablockers on systolic and diastolic left ventricular function during therapeutic hypothermia
  • Multifunctional pacemaker systems for cardiac resynchronization therapy (CRT)

Research aims

Most minimally invasive procedures restrict the access and direct vision to the regions which require surgery. Such procedures require intra-operative image modalities such as x-ray, ultrasound or endoscopic images to be able to monitor the procedure in real-time.  In many cases this information is not sufficient to perform the procedure accurately and safely. Merging information acquired pre-operatively, mainly from for instance MRI, CT or PET, with intra-operative data can increase the basis for decisions and thereby improve the safety and accuracy of the procedure. The Medical Robotics, visualization and navigation group develops cutting edge technological solutions which support minimally invasive procedures. In particular, the group is focused on developing real-time image-segmentation and - registration methods. Visualization and navigation is required to present the medical images to the surgeon intra-operatively. 3D video will be more and more cross-linked with medical image information and move toward robotics and automation of surgical procedures. The research group is doing research in all these fields of technology facilitating minimally invasive surgery.

Method Development and Industry Collaboration Research

Clinical Testing Work Group

Group Leader: Karl Øyri, PhD

In 2017 36 new project inquiries from companies were made to the TestBed. Seven were terminated 14 projects are currently in the planning phase, 2 are ongoing, and 13 projects were completed in 2017. The complex projects involving early phase technologies often have long planning phases due to protocol development and adjustments, regulatory requirements and resource mapping at the hospital.

Inven2, the technology transfer office (TTO) at Oslo University Hospital handles legal contracts and economy for the industry-sponsored projects in the testbed. We continue the close collaboration with Norway Healthech. SMI is present at Aleap in Forskningsparken on a weekly basis to meet with companies and Norway Healthtech.

The quality coordinator in SMI is continuously involved in refinement of the quality systems at The Intervention Centre. A God Clinical Practice (GCP) framework has been implemented in the Quality System, and can be used if companies are in need of GCP compliant services.

Ongoing Projects:

The Nordic Network of Testbeds Project funded by Nordic Innovation was finalized in 2017. With continued funding from Nordic Innovation the project ended with the establishment of Nordic Proof where all project partners are collaborating in a consortium of testbeds.  Nordic Proof provides professional services for testing of new and innovative healthcare products in the Nordic region. With a “one point of contact” for all the test beds, Nordic proof aim to match (supply? provide?) the companies with a variety of test facilities to meet industry needs.

Development of organizational performance and innovative logistics

Group Leader: Karl Arne Johannessen

New ambitions: SMI has an ambition to expand its competence and capabilities to a new dimension; how may our experience and competence related to technological innovations be extended to the organizational perspective?

Whereas new solutions from technology research are accelerating, the impact of their implementation will not be achieved at full potential if the involved organizational solutions are unchanged. Despite implementation of numerous new technological solutions in a large span of clinical activities, many services remain organized and operate with a traditional approach that may delay and even obstruct improvements in resource utilization and quality. We have the ambition to identify basic cultural and organizational characteristics that may trigger innovative transformation of clinical services in concordance with technological innovations in a two-fold perspective:

  • How may we improve logistics in services which implement new technological solutions?
  • How may we extend such experience and logic to clinical services that are not directly involved in the technological development, but where services may replicate and benefit from experiences from more technology based services?

The BigMed Project

Group Leader: Thomas Smedsrud

The BigMed project is an ICT Lighthouse project funded by The Research Council of Norway to promote development and technology and services with advanced computer science. The project is managed and owned by the Intervention Centre at Oslo University Hospital, and includes a broad consortium of partners from several other departments in the hospital, three faculties at the University of Oslo, industry organisations and four patient associations. The project aims to lay a foundation for implementing precision medicine and big data analytics in healthcare, and will do so through testing and developing of ICT solutions to support the implementation of precision medicine in three clinical areas: rare diseases, sudden cardiac death and metastatic colorectal cancer. When developing solutions, the cross-competence teams in BigMed will discuss barriers and identify actions to overcome them. The barriers for implementation of precision medicine include legal, ethical and social aspects that must be discussed and addressed.
