Randomized Controlled Trial
Comparison of pathological outcomes after transanal versus laparoscopic total mesorectal excision: a prospective study using data from randomized control trial.
Total mesorectal excision (TME) is the standard procedure for middle lower rectal cancer, and transanal total mesorectal excision (taTME) was founded as a valid alternative to the open and laparoscopic TME. The quality of the procedure performed is important for prognosis of patients. This study was designed to compare the pathological results of taTME with those of laparoscopic TME (laTME), based on the data from a randomized control trial (RCT: NCT02966483). ⋯ The pathological outcomes between transanal and laparoscopic total mesorectal excision are similar. The rate of positive resection margin could not be significant decreased, nonetheless the decrease trend could be shown.
