Intraoperative Doppler Ultrasonography with Superb Microvascular Imaging for Intestinal Perfusion Assessment in Colorectal Cancer Surgery: A Prospective Pilot Study. [PDF]

J Anus Rectum Colon
Objectives: Intraoperative indocyanine green fluorescence imaging (ICG-FI) reduces anastomotic leakage, but has limitations related to contrast agent use, repeatability, and timing-dependent interpretation.

Comparison of quantitative laser speckle contrast and indocyanine green imaging for intestinal perfusion measurements in robot assisted surgery. [PDF]

Sci Rep
Adequate perfusion is essential to prevent anastomotic leakage in intestinal and rectal surgeries. This study compares Laser Speckle Contrast Imaging (LSCI) and Indocyanine Green Fluorescence Angiography (ICG-FA) for assessing blood flow in intestinal ...

Chronic, but not acute, treatment with GLP-2 and GIP in combination increases glucose absorption in the isolated vascularly perfused rat intestine. [PDF]

Physiol Rep
The gut hormones, glucagon‐like peptide‐2 (GLP‐2) and glucose‐dependent insulinotropic polypeptide (GIP), may be important regulators of intestinal nutrient absorption.

From intraoperative visual inspection to postoperative quantification: ICG fluorescence angiography for acute mesenteric ischemia validated by histopathology. [PDF]

BMC Surg
Introduction Acute mesenteric ischemia (AMI) is a rare and life-threatening condition that leads to intestinal necrosis. Accurate assessment of intestinal viability and perfusion is crucial for reducing its high mortality rate.

Imaging PPG for In Vivo Human Tissue Perfusion Assessment during Surgery

Journal of Imaging, 2022
Surgical excision is the golden standard for treatment of intestinal tumors. In this surgical procedure, inadequate perfusion of the anastomosis can lead to postoperative complications, such as anastomotic leakages.
