Faculty of Medicine

As a part of the “Excellence Initiative – Research University” program, a new core facility – the Organ-Specific Medicine Laboratory – is starting operations at the Medical University of Gdansk. The unit was created thanks to the experience of the staff at the Department of General, Endocrine and Transplant Surgery, and the Department of Oncological Surgery, which were established within the structure of the Faculty of Medicine.


  • freezer: up – 80 degr. C
  • stock of liquid nitrogen + Dewar flas
  • centrifuges – 2 Hettich EBA 200 units, and an older model (up to 6000 RPM)
  • ultrasound scanners – 3 units, two full-size, high-quality ultrasound scanners, and one POCUS (point-of-care) devic
  • laparoscopic columns, including those with ICG imaging
  • ICG imaging camera (for open surgeries)
  • laser Doppler scanner
  • gamma camer
  • neuromonitoring


The Organ-Specific Medicine Laboratory care facility provides access to clinical expertise and facilitates access to patients, including tissue and clinical data, for MUG, FarU and external collaborators.

Scope of activities conducted:

  • recruitment of patients from specific clinical areas for basic research and clinical trials
  • designing/consulting on the design of research studies involving patients for MUG colleagues and external collaborators
  • conducting non-commercial and commercial clinical trials
  • collecting, cataloguing and freezing tissue samples from patients
  • collecting, cataloguing and transferring patients’ blood samples to the laboratory
  • collecting clinical information on patients
  • analysis of clinical data of patients for scientific resear
  • interpreting the clinical context of scientific findings

The foregoing capabilities of the Core Facility enable a translational approach to science, and will improve collaboration between MUG and external units. The Core Facility provides access not only to patient-obtained biological samples and clinical data, but more importantly: to experts who support study planning and result interpretation in a clinical context.

Clinical areas of the Core Facility

Clinical areas are reflected by the organizational structure of the Department of Oncology, Transplantation and General Surgery, which operates at UCK (Fig. 1).

Clinical activities conducted include:

  • patients with acute abdominal conditions (about 100-200 per year)
  • patients with hernias (about 50 per year)

  • patients with kidney failure undergoing kidney transplantation (about 100 per year)
  • patients with benign and malignant diseases of the bile ducts, gallbladder and liver undergoing surgery (about 50-100 per year) and locoregional treatment(about 250 per year)
  • patients with benign and malignant pancreatic diseases undergoing resection surgery (about 50 per year)
  • morbidly obese patients undergoing bariatric surgery (about 200 per year)
  • patients with upper gastrointestinal tract cancers (of the esophagus and the stomach) undergoing resection procedures (about 30 per year)
  • patients with unresectable upper gastrointestinal tumors subjected to parenteral and enteral nutrition (about 50 per year)
  • colorectal cancer patients undergoing resection surgery (approximately 200 per year)
  • patients with proctological diseases undergoing topical treatment (approx. 1000 per year)
  • patients with malignant and benign thyroid diseases undergoing resection procedures (about 250 per year)
  • patients with malignant and benign adrenal diseases undergoing resection procedures (about 50 per year)
  • patients with malignant breast diseases undergoing resection surgery (approx. 400 per year)
  • patients with malignant soft tissue diseases (melanomas and sarcomas) undergoing resection procedures (about 50 per year)
