Nowadays, laparoscopic colorectal resection is gaining widespread popularity because it is associated with less blood loss, quicker recovery, and shorter hospitalization than open surgery as well as equivalent oncological benefits. In laparoscopic surgery, bowel transection and reconstruction are very important for  oncological efficacy and surgical safety, especially avoidance of anastomotic leakage (AL). Although multiple factors such as total mesorectal excision (TME) surgery, low anastomosis, preoperative chemoradiation, advanced tumor stage, and multiple firings of the linear stapler are proven to increase the risk of postoperative AL, the technical aspect of colorectal transection and anastomosis is the dominant contributing factor [1].

Since the introduction of the double-stapled technique (DST) anastomosis described by Knight and Griffen, sphincter preservation is more feasible, and is, therefore, frequently used in laparoscopic rectal cancer surgery [2]. However,...
