INTRODUCTION: Exact assessment of intestinal viability is necessary, since the risk of anastomotic complications increases due to the reduction in anastomotic blood supply. Near-infrared spectroscopy is useful in assessing blood flow because it allows real-time monitoring and quantifying of tissue oxygen saturation. Herein, we report a case in which two intestinal resections were performed safely by using near-infrared spectroscopy to evaluate the blood flow at the anastomotic sites.
PRESENTATION OF CASE: A 67-year-old man was diagnosed with multiple cancers of the transverse colon and rectum. Laparoscopic transverse colon resection and low anterior resection were performed along with left colic artery-preserving lymphadenectomy, including tissues around the origin of the inferior mesenteric artery. After mesenteric dissection, the tissue oxygen saturation of the proximal side and distal side stumps were 93% and 87%, respectively. The tissue oxygen saturation of the anastomotic proximal side after mesenteric dissection was 76%, thus confirming sufficient blood flow.
DISCUSSION: Performance of transverse colon resection and low anterior resection for multiple cancers of the transverse colon and rectum resulted in blockage of the blood flow to the descending colon; therefore, it was necessary to preserve the blood flow to the descending colon by preserving the left colic artery. Near-infrared spectroscopy was used to evaluate blood flow to the anastomotic sites, in order to perform the surgery safely.
CONCLUSION: Near-infrared spectroscopy is a safe, simple and low-cost method for assessing blood flow intraoperatively in conjunction with left colic artery-preserving surgery.
