Abstract:
Adequate blood flow in anastomosis is of paramount importance to prevent anastomotic leakage. However, it is sometimes difficult to predict the viability of the intestine during surgery. During left-sided colectomy, blood flow on the remnant distal bowel is supplied only from the middle and inferior rectal arteries. The blood backflow after the root ligation of the inferior mesenteric artery is often said to be kept up to promontorium levels; however, this premise is actually based on experience, without reliable evidence. Here, we introduce the intraoperative evaluation of blood flow on the remnant distal bowel during left-sided colectomy using an indocyanine green fluorescence technique.
