Indocyanine Green Fluorescence Angiography (ICG-FA) in Revisional Bariatric Surgery
Prospective Single-center Diagnostic Parallel-group Study to Determine the Minimal Dose of Indocyanine Green to Observe Vascular Perfussion in Revisional Bariatric Surgery.
Source: ClinicalTrials.gov · Last updated 27 Mar 2026
Brief summary (registry, in English)
This study will compare different doses of a green fluorescent product that is administered during weight loss surgery in order to observe where blood vessels are located. There is uncertainty around the optimal dose of this product for patients with obesity, so this study will aim to study if the dose in the minimal range recommended by international guidelines is sufficient for most patients or if higher doses are needed with increasing body mass index.
