Overview
Introduction:
The aim of the study was to evaluate the results of fluorescence angiography for assessing anastomotic perfusion after resection of the sigmoid colon and rectum since its introduction into clinical practice at the authors´ workplace and to evaluate the incidence of necessary resection line repositioning based on the quality of perfusion, and also to record any complications in anastomotic healing.
Method:
Retrospective unicentric analysis of prospectively collected data from patients with resection of the sigmoid colon and rectum with primary anastomosis. The patient set included 50 patients, 27 males and 23 females; the median age was 64.5 years (33–80). Forty-four patients were indicated for resection for cancer of the sigmoid colon or rectum, while 6 patients had a benign disease. Twenty-nine patients underwent total mesorectal excision with coloanal mechanical or hand-sewn anastomosis and 21 underwent resection of the sigmoid colon or upper rectum with mechanical anastomosis. Prior to the construction of the anastomosis, assessment of perfusion of the anastomotic segments by near infrared (NIR) indocyanine green (ICG) fluorescence angiography was performed in all patients. The quality of perfusion of the mesocolon and bowel wall and its impact on moving the resection line and complications of anastomotic healing 30 days postoperatively were all evaluated.
Results:
Assessment of perfusion using fluorescence angiography was technically successfully performed in all 50 patients. In 5 cases (10%) the resection line had to be moved for signs of poor perfusion of the bowel wall. Postoperatively, healing of the anastomosis was complicated in four patients (8%). Dehiscence was recorded in 3 patients (10.3%) with total mesorectal excision and in 1 patient (4.8%) after resection of the sigmoid colon and upper rectum.
Conclusion:
The presented results indicate that fluorescence angiography may lead to a decrease in the incidence of anastomotic dehiscence after colorectal resections by mapping in detail the perfusion of the anastomosed segments.
