Role of Intraoperative Fluorescence Angiography using Indo Cyanine Green (ICG) during Colorectal Cancer Surgery

Intervention1: ICG Arm: Assessment of colorectal vascularity after a bolus ICG injection intravenously at the time of surgery.
Control Intervention1: Non ICG arm: Conventional assessment of colorectal vascularity without ICG assessment under white light
