Current hotspot and future development of laparoscopic rectal cancer surgery

Abstract

The clinical practice andresearch of laparoscopic rectal cancer surgery have been attracting much more attention. Based on the high-level evidence published in recent years, laparoscopic surgery for rectal cancer seems to be well documented and effective. Howeverseveral studies have shown that laparoscopic surgery has a higher incidence of circumferential margin positive and incomplete total mesorectal excision, and further research results are still challenging. Therefore, the NCCN guideline for Rectal Cancer (version 2018) recommended that laparoscopic surgery for rectal cancer can be used in clinical practice. However, for patients with a risk of positive circumferential resection margin, open surgeryis still recommended. In addition, laparoscopic assisted transanal total rectal resection is also a hot issue in recent years. Existing studies have shown that it is safe and feasible. Whether it will become atrendin mid-low rectal cancer surgery, is still worthy of expectation, and more high-level evidence is needed in the future.
