Abstract
Low rectal cancer has always posed surgical challenges to gastrointestinal surgeons. Transanal total mesorectal excision (taTME) is a novel approach to radical resection for low rectal cancer. Compared with conventional laparoscopic TME (laTME), taTME is relevant to the benefits of better vision of the mesorectal plane, feasibility of operating in a narrow pelvis, and exact definition of distal resection margin, which may lead to a higher possibility of free circumferential resection margin, better quality of TME specimen, and lower conversion rate. Although there are concerns about its long-term oncological outcomes and complex learning curve, taTME is a promising alternative for rectal cancer. In this review, we discuss the application status and prospects of taTME.
Highlights
Rectal cancer is one of the most common cancers worldwide
Transanal Total Mesorectal Excision difficulties in the narrow pelvis; it may promise a higher possibility of free circumferential resection margin (CRM) and distal resection margin (DRM), a better quality of total mesorectal excision (TME) specimen, and better functional outcomes over conventional TME, especially when treating male patients, obesity, narrow pelvis, and large tumors
These findings indicated that the oncological short-term outcomes after Transanal total mesorectal excision (taTME) were acceptable and that taTME may be a promising alternative for rectal cancer
