Robotic versus transanal total mesorectal excision in sexual, anorectal, and urinary function: a multicenter, prospective, observational study.

Comparison of pre- and postoperative scores showed that TaTME led to a highly significant decline in fecal function (Wexner score, p < 0.001; LARS score, p < 0.001), but the actual impairment was mild: the mean Wexner score remained in the lower quarter postoperatively (Fig. 2 ).
