Core Tip

Core Tip: Colorectal anastomotic leakage, a severe postoperative complication, is associated with high morbidity, hospital readmission, and overall healthcare costs. Early detection of colorectal anastomotic leakage remains a challenge in clinical practice. Some decision models have been developed to increase the diagnostic accuracy of this event. A score designed with easily accessible variables could have a positive impact on timely diagnosis of colorectal anastomotic leakage and could minimize healthcare costs.
