Comparative efficacy analysis of laparoscopic-assisted transanal total mesorectal excision laparoscopic transanal mesorectal excision for low-lying rectal cancer.

Department of Gastrointestinal Surgery, Nanhua Hospital Affiliated to University of South China, Hengyang 421002, Hunan Province, China.
Background: With the continuous development of laparoscopic techniques in recent years, laparoscopic total mesorectal excision (LapTME) and laparoscopic-assisted transanal total mesorectal excision (TaTME) have gradually become important surgical techniques for treating low-lying rectal cancer (LRC). However, there is still controversy over the efficacy and safety of these two surgical modalities in LRC treatment.
Aim: To compare the efficacy of LapTME TaTME in patients with LRC.

Rectal gastrointestinal stromal tumors (GISTs) are often asymptomatic and may be detected as giant tumors. This may require highly invasive surgery for radical resection. Here, we describe a 74-year-old man with a locally advanced non-metastatic GIST in the right anterolateral wall of the lower rectum.

The role of laparoscopy in rectal cancer surgery has evolved considerably since the early 2000s. Initial randomized trials, such as COLOR II and COREAN, indicated that laparoscopic approaches offered similar pathological outcomes with better postoperative recovery than open surgery. In contrast, trials like ACOSOG Z6051 and ALaCaRT suggested noninferiority could not be established.

Importance: Previous studies have demonstrated the advantages of short-term histopathological outcomes and complications associated with transanal total mesorectal excision (TME) compared with laparoscopic TME. However, the long-term oncological outcomes of transanal TME remain ambiguous. This study aims to compare 3-year disease-free survival of transanal TME with laparoscopic TME.

Lateral lymph node dissection (LLND) is getting global attention as an a surgical option to reduce local recurrence in locally advanced rectal cancer. As the transanal total mesorectal excision (TaTME) is gaining popularity worldwide, a novel LLND approach was established adopting a two-team approach that combines the transabdominal and transanal approaches using the TaTME technique. This narrative review describes the advantages, anatomical landmarks, surgical techniques, and pitfalls of transanal LLND (TaLLND).
