Postoperative complications in colorectal cancer surgery lack uniform guidelines

A systematic review of 135 articles on postoperative complications from colorectal cancer surgery underscores significant disparities in research focus and treatment guidelines. Notably, anastomotic leakage and postoperative infections accounted for 35% and 25% of studies, while port-site metastases and cardiovascular dysfunctions received limited attention. The prevalence rates of complications varied widely, from 3% to 20%, highlighting the need for standardized management protocols and further research into less-studied complications to improve patient outcomes.
