Abstract

Anastomotic leak (AL) is one of the worst complications of rectal anterior resection (RAR) and its incidence varies according to the anatomical site, increasing in lower anastomoses. Many etiological factors have been evaluated and most of these are related to bowel perfusion. Indocyanine green-enhanced fluorangiography (ICGf) has been proposed to help surgeons assess colonic perfusion with higher reliability than subjective clinical judgment. The aim of the study was to evaluate the efficacy of this tool in patients subjected to elective laparoscopic RAR for extraperitoneal rectal cancer. All the patients subjected to elective laparoscopic RAR for extraperitoneal rectal cancer between May 2015 and January 2017 were considered. In all of them, ICGf was performed to evaluate bowel perfusion. The control group included an equal number of patients subjected to the same procedure from January 2014 to April 2015, before the start of routine use of this tool at our institution. The endpoint of the study was to compare the incidence of AL between the two groups. A total of 33 patients were included in both groups. Relying on fluorescence intensity in the indocyanine green (ICG) group, we changed the level of resection in 6/33 patients (18.2%). An AL developed in 2/33 patients (6%) in the ICG group versus in 7/33 patients (21.2%) in the control group. The routine use of this technique may help surgeons in selecting the best level of proximal bowel resection during RAR.
