Laparoscopic ultralow anterior resection combined with per anum intersphincteric rectal dissection for lower rectal cancer.

Rectal resection with total mesorectal excision is perhaps the most technically challenging of laparoscopic procedures, and the purpose of this study was to show that laparoscopic ultralow anterior resection is feasible for lower rectal cancer. Seven patients with lower rectal cancer were treated in this way with a satisfactory outcome in each case, and on the basis of this limited study, we suggest that extension of laparoscopy to the treatment of very low rectal lesions may be of advantage.
