Exploratory trial evaluates intestinal perfusion using Doppler ultrasonography in colorectal cancer surgery, suggesting enhanced assessment.
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.
