Examination of Rectal Blood Supply During Rectal Cancer Surgery Using Laser Speckle Contrast Imaging

Résumé succinct

This multicentre feasibility study evaluates the feasibility of performing laparoscopic Laser Speckle Contrast Imaging (LSCI) measurements of rectal perfusion during rectal cancer surgery. To our knowledge, LSCI has not previously been applied laparoscopically for intraoperative assessment of rectal perfusion in this setting. Laparoscopic LSCI measurements will be compared with indocyanine green fluorescence imaging, and associations between quantitative measures of colorectal perfusion and postoperative outcomes, including anastomotic leakage, will be explored.
