Doel van het onderzoek
This pilot study aims to report on the diagnostic value of indocyanine green and fluorescence laparoscopy on vascularization defects of the stomach and spleen during antireflux surgery. It is our hypothesis that many splenic and gastric infarctions occur without the surgeon noticing, and there may be a connection between postoperative pain and this infarction.
Onderzoeksopzet
Visual inspection of fluorescence intensity as representation of perfusion, before and directly after ligation of the gastrosplenic ligament.
Onderzoeksproduct en/of interventie
The main endpoint of this study is the observation of a perfusion defect in the spleen and/or gastric fundus. This endpoint will be measured by visual inspection of the blood flow of the spleen and gastric fundus during surgery, as made possible by the indocyanine green. As a control measurement, a visual assessment will be performed both before and after ligation of the gastrosplenic ligament. Independent observations of the surgeon, assistant and researcher will be recorded.
