A Study of Perfusion of Colorectal Anastomosis Using FLuorescence AnGiography (FLAG-trial)

Not Applicable

Completed

• Conditions: Sigmoid Cancer; Rectal Cancer

• Registration Number: NCT03390517
• Lead Sponsor: State Scientific Centre of Coloproctology, Russian Federation

Brief Summary

This is a randomized, controlled, parallel study to determine the difference in post-operative anastomotic leak rate of colorectal anastomosis where colon and rectal tissue perfusion is evaluated using fluorescence angiography with indocyanine green and without this method.

Detailed Description

The design involves random allocation of eligible patients to operation with colorectal anastomosis and intraoperative fluorescence angiography with indocyanine green and operation alone. After surgery on 7-8 POD patients are examined to two sides X-Ray proctography performed by introducing 100 ml of water-soluble liquid contrast material through the anus over the anastomotic line by a Foley catheter for diagnosis of anastomotic leakage.
