**8. Conclusions**

Laparoscopic anterior resection (LAR) is nowadays routine practice in specialized high-volume centers, with equivalent oncological outcomes to open surgery. Anastomotic leakage (AL) remains one of the most threatening complications in colorectal surgery with the incidence of up to 20%. Therefore, recognition of the risk factors of postoperative complications is essential in order to be prevented. Moreover, one must underline the importance of some risk factors such as age, nutrition status of the patient, experience of the surgeon, and many other factors that influence outcome of colorectal surgery. Some risk factors can be modified before the intervention to prevent postoperative complications. Contrary to that, long-term postoperative complications may promote tumor recurrence and decrease survival.
