Evaluation of Anastomosis With ICG Fluorescence Method Using VISERA ELITE2 During Laparoscopic Colorectal Cancer Surgery

Abstract

Aim: In colorectal cancer surgery, the efficacy of intestinal blood flow evaluation with the indocyanine green (ICG) fluorescence method using the VISERA ELITE2 system was investigated.

Patients and methods: Participants in this study comprised 50 patients who underwent elective laparoscopic colorectal cancer surgery at the Department of Surgery, the Jikei Daisan Hospital. With the ICG fluorescence method, whether it was necessary to change the intestinal transection line for anastomosis was evaluated.

Results: For three cases of rectal cancer, the oral transection line determined from macroscopic observation was judged to offer insufficient blood flow according to the ICG fluorescence method. The transection line for anastomosis was changed according to fluorescence. None of these cases showed complications.

Conclusion: The ICG fluorescence method may allow safe anastomosis in colorectal surgery for cancer.
