Recognition of the gist of laparoscopic sphincter-preserving surgery in ultra-low rectal cancer

Abstract

The laparoscopic technique has been applied for over 20 years and its superiority of minimally invasive surgery has been enlarged after combining with 3D technology. Application of this minimally invasive technology is widely acknowledged in rectal cancer surgery, especially in ultra-low rectal cancer. The surgeons can have a good view of the structure such as nerves, fascia in pelvic cavity sufficiently with the help of high definition vision, and recognize that not only the configuration of anus should be preserved but also its function. Therefore, a higher requirement on operative skill is made to the surgeons. In this article, based on our experience and realization, we reconsider and review the key technology of laparoscopic anus-preserving surgery in ultra-low rectal cancer from the aspects of vessel handling, retrorectal space mobilization, pelvic autonomic nerve preservation and intersphincteric groove management, aiming to promote standard treatment, and at the same time, to result in benefits for more patients with ultra-low rectal cancer.
