Summary

The goal of this clinical trial is to evaluate and compare the clinical utility of Indocyanine Green (ICG) fluorescence angiography and Laser Speckle

Contrast Imaging (LSCI) in assessing intraoperative tissue perfusion at the anastomotic site during colorectal resection in \[describe participant population/primary condition; could include any of the following: sex/gender, age groups, healthy volunteers\]. The main question\[s\] it aims to answer \[is/are\]:

What is the clinical utility of Indocyanine Green (ICG) fluorescence angiography compared to Laser Speckle Contrast Imaging (LSCI) in assessing intraoperative tissue perfusion at the anastomotic site during colorectal resection?

Participants will undergo a laparoscopic/robotic (where an extracorporeal anastomosis formed)/open colectomy with ligation of the inferior mesenteric artery and a planned anastomosis of 5cm to 15 cm from the anal verge where both ICG and LSCI modalities will be applied to all subjects.

DEVICE

ActivSight™ Intraoperative Imaging System

ActivSight™ Intraoperative Imaging System which consists of an infrared-sensitive monochrome imaging sensor adapter and a customized light source with 1 or more coherent laser sources. In LSCI mode, proprietary algorithms detect perfusion using motion in real time, projecting a false color overlay on the standard white light laparoscopic image. This Food and Drug Administration-approved technology has the capacity for both ICG NIRF and LSCI.
