Intraoperative Doppler Ultrasonography with Superb Microvascular Imaging for Intestinal Perfusion Assessment in Colorectal Cancer Surgery: A Prospective Pilot Study
Objectives: Intraoperative indocyanine green fluorescence imaging (ICG-FI) reduces anastomotic leakage, but has limitations related to contrast agent use, repeatability, and timing-dependent interpretation. We conducted an exploratory trial of a Doppler ultrasonography method using a high-frequency probe with superb microvascular imaging (SMI) to assess intestinal perfusion during colorectal cancer surgery.
