Indocyanine Green Fluorescent Imaging in Robotic Assisted Rectosigmoidal Resection; a Multicenter Assessment of Interobserver Variation and Comparison With Computer-based Pixel Analysis

A serious complication to colorectal surgery is anastomotic leakage (AL). AL increases post-operative mortality, decreases long-term survival, reduces the functional result and reduces qual-ity of life. Studies suggest that performing an indocyanine-green enhanced fluorescent angi-ography (ICGeFA), blood perfusion in the bowel can be visualised. It is suggested that using this procedure the relative risk of AL is reduced about 54-67%. With this project we wish to evaluate the feasibility of the procedure, and, if proven feasible, to plan further studies evaluating the procedure.
