Key result
Contemporary series show an anastomotic leak rate of 1-19% in colorectal resections, prompting this review of risk factors and an algorithm for early detection.
Why the study?
Anastomotic leak rates remain 1–19% after colorectal resections, continuing to drive morbidity and mortality despite improvements in surgeon training and patient care.
This narrative review summarizes factors affecting the integrity of colorectal anastomosis and presents an algorithm for early detection of anastomotic failure.
Requires ongoing vigilance for leaks in colorectal surgery; leaves open optimal prevention strategies.
Despite vast improvements in training of colorectal surgeons and the care of patients undergoing colorectal resections, contemporary series still show an anastomotic leak rate of 1– 19%, which continues to contribute to the morbidity and mortality to these patients. New technologies and more recent studies investigating factors affecting the integrity of colorectal anastomosis have been published. Understanding the factors that increase the risk of anastomotic leak allows surgeons to take steps to prevent and ameliorate these risks. We aim to present an evidence-based narrative review relating anastomotic failure and an algorithm for early detection.

Ang et al. (2024) conducted a review in Anastomotic leak in colorectal surgery. Factors affecting the integrity of colorectal anastomosis was evaluated. Contemporary series show an anastomotic leak rate of 1-19% in colorectal resections, prompting this review of risk factors and an algorithm for early detection.
