Indocyanine Green Fluorescence Angiography (ICG-FA) in Revisional Bariatric Surgery

Recruiting now · Not applicable

Conditions studied: Obesity, Bariatric Surgery

In brief

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.
