In colorectal surgery, hand suturing and stapling are routine methods for performing intestinal anastomoses, and these methods appear to be similar in terms of clinical safety. Despite several years of experience with surgical procedures as well as improvements to the medical devices, problems with disturbed anastomotic healing leading to leakage and stenosis after colorectal surgery remain a significant challenge for surgeons. In addition, preoperative radiotherapy has been shown to increase the risk of anastomotic leakage even further.
