Technical points of 4K laparoscopic assisted transanal total mesorectal excision / 中华消化外科杂志

ABSTRACT

Surgical treatment of low rectal cancer is a difficult point in colorectal surgery, which has the problem of mutual restriction between radical resection and functional protection. With the development of laparoscopic total mesenterectomy, minimally invasive operation through anal endoscopy and the gradual improvement of the concept of natural orifice transluminal endoscopic surgery, the transanal total mesorectal excision (taTME) is formed in line with the principle of radical resection of rectal cancer. On the premise of ensuring radical resection, taTME can maximize organ preservation and function protection, and improve the quality of life of patients. 4K laparoscopic system can provide a clear surgical field and improve the surgical precision, which is helpful for the accurate anatomy of low rectal cancer. The authors share the clinical experience of 4K laparoscopy assisted taTME in order to provide references for surgical colleagues.
