Fluorescent Angiography Used to Evaluate the Perfusion Status of Anastomosis in Laparoscopic Anterior Resection

Colorectal Cancer

Abstract

Background

Anastomotic leakage after gastrointestinal surgery is associated with significant morbidity and mortality.1 Insufficient vascular supply is one cause.2 Recent reports of using intraoperative indocyanine green (ICG) fluorescent angiography to evaluate whether perfusion of the anastomosis is adequate has yielded positive outcomes.3 6 The authors describe their use of ICG-enhanced fluorescence angiography in a laparoscopic anterior resection.

Methods

The patient was an 80-year-old with an upper rectal adenocarcinoma and significant cardiovascular risk factors. Fluorescence angiography with 0.4 mg/kg of ICG was administered intravenously just before the colorectal anastomosis was fashioned. A near-infrared (NIR) laparoscopic camera (KARLSTORZ, GmbH & Co. KG, Tuttlingen, Germany) was used to inspect the anastomosis. For this video, 0.4 mg/kg of ICG also was injected after ligation of the inferior mesenteric artery to demonstrate the appearance of a poorly perfused sigmoid bowel.

Results

Just before the staple was fired to fashion the colorectal anastomosis, an intravenous bolus of ICG was administered. Within seconds, vessels on both ends of the anastomosis turned fluorescent blue, indicating adequacy of perfusion. The use of ICG did not significantly lengthen the operative time (285 min) because its effect appeared within seconds after its administration. The patient recovered well and was discharged on postoperative day 5. Another four patients who also underwent intraoperative fluorescent angiography for left-sided colorectal lesions did not experience anastomotic leakage.

Conclusion

The study showed that ICG fluorescent angiography is a simple and quick intraoperative tool for evaluating the perfusion of the anastomosis. The authors’ experience with ICG fluorescent angiography has shown promising results, with a 0 % anastomotic leak rate.
