Lateral pelvic lymph node (LPLN) metastases are found in some patients with advanced primary rectal cancer. Although preoperative chemoradiotherapy (CRT) is current standard care for locally advanced rectal cancer, some studies have demonstrated that CRT followed by total mesorectal excision (TME) might not be sufficient [1, 2]. LPLN dissection (LPLND) for selected cases with enlarged LPLN is a treatment option and an essential surgical technique for colorectal surgeons. However, LPLN metastases usually occur at the bottom of the lateral pelvis along the internal iliac vessels. Therefore, laparoscopic LPLND is a technically complex and challenging procedure, especially in obese patients with narrow pelvises.

Transanal TME (TaTME) is the latest promising approach for rectal cancer [3, 4]. Atallah et al. compared the shape of the rectum to a capital letter “L” and proposed that the horizontal portion of the rectum is the best approach from the in-line vantage point of...
