Description
ICG/NIR fluorescence imaging has become one of the most valuable technologies in minimally invasive surgery. Especially for intra-operative check of visceral perfusion, the visualisation of biliary structures or lymph node mapping.
FLUORESCENCE GUIDED SURGERY
Fluorescence refers to the ability of some atoms and molecules to absorb light at a particular wavelength (of excitation: Ex) and then to emit light of a longer wavelength during a short-lived emission (Em). This means:
- Fluorescence allows us to assess blood flow in tissues very well, e.g. anastomosis visualization
- In the case of tumors, a good visibility of the tumor boundery, so that an exact removal is possible without opening the tumor. The risk of tumor cells spreading in the situs is significantly reduced
- Less stress for the staff in the clinics. Cost and time savings
- Metastases become visible
- Visualization of the lymphatics are possible
- Presentation of the choledochus
- Elaborate marking with radio markers is not necessary, therefore less burden for the patient
- Visualization of the anastomosis in oesophageal carcinoma
- Various other indications
As of today, we are still at the beginning of the possibilities for indications with fluorescence. Due to new innovative techniques, such as the hand-held camera, fluorescence will also become more and more important in open oncological surgical techniques, e.g. in the parathyroid gland (autofluorescence).
