Core Tip

Core tip: Anastomotic leakage after anterior resection for rectal cancer is still common. Several preoperative risk factors may inform the surgeon of the leakage risk. The surgeon might choose to perform a diverting stoma to mitigate this risk, or to construct an end colostomy and thus avoid an anastomosis altogether. Intraoperatively, clinical judgment of the viability of the anastomosis is not reliable. However, research using blood perfusion measurement technology has evolved in recent years; technology using near-infra red light seems to be promising, allowing assessment of the bowel perfusion. In the future, such technology may aid in the decision-making concerning colorectal anastomoses.
