• Radical tumor resection – curative procedure in colorectal cancer
• Anastomotic leaks (AL) are widely considered the Achilles heel of colorectal surgery
• UK SISG: a “leak of luminal contents from a surgical join between two hollow viscera”
Background
Bruce J, Krukowski ZH, Al-Khairy G, Park KG. Systematic review of the definition and measurement of anastomotic leak after gastrointestinal surgery. Br J Surg 2001;88:1157–1168.

• Incidence of AL varies between institutions depending on the definition chosen
• Certain factors are known to increase the likelihood of an AL

• Identify risk factors for AL
• Assess the correlation between the observed risk factors and AL
