Overview
Brief Summary
Anastomotic leakage (AL) is one of the most-feared postoperative complications after anterior resection of rectal cancer. This complication compromises both short term and long term outcome of patients. The incidence of AL after anterior resection was approximately 6-11%. Although several risk factors for AL such as male sex, smoking, tumor location, longer operative time, intraoperative blood loss had been reported in previous studies, the incidence of AL did not meet a significant decrease. So far there is no multi-site observational study on incidence and risk factors of AL after anterior resection in China, therefore this study aims to work on this issue and provide evidence for clinical practice.

Outcomes
Primary Outcomes
Anastomotic leakage
Time Frame: 14 days after surgery
Anastomotic leakage is defined as a defect of the intestinal wall integrity at the colorectal anastomotic site leading to a communication between the intra- and extraluminal compartments.
