The Impact of Indocyanine Green-enhanced Fluorescence Imaging on Bowel Transection in Left-sided Colorectal Resection
The Impact of Indocyanine Green-enhanced Fluorescence Imaging on Bowel Transection in Left-sided Colorectal Resection
The aim of this study was to evaluate the impact of fluorescence imaging on the location of
 colorectal transection lines based on evaluation of perfusion with indocyanine green, how
 it's going to affect surgical planning and its possible benefits in reducing anastomotic
 leakage.
During surgery, the line of intended bowel transection would be determined by the surgeon.
 Then the anesthesiologist will administer a bolus of 5mg ICG intravenously (2.5mg/ml, 2ml),
 followed by 10ml normal saline flush. The perfusion of colon will be assessed via
 fluorescence angiography. The actual bowel transection, after ICG fluorescence study, would
 be compared with the intended bowel transection site. The difference in terms of distance and
 either more proximal or distal is recorded. Then bowel anastomosis is completed in the usual
 manner.
Inclusion Criteria:

 -  All left-sided colorectal resection involving division of inferior mesenteric artery

 Exclusion Criteria:

 -  Patients with a history of adverse reaction or known allergy to ICG, iodine, or iodine
 dyes. Pregnant and/or lactating patients.
