Outcomes of transanal vs laparoscopic total mesorectal excision for mid and low rectal cancer under routine clinical practice conditions
Comparative Outcomes of Transanal and Laparoscopic Approaches to TME
Overview
This study evaluates the oncologic outcomes of transanal total mesorectal excision (TaTME) compared to laparoscopic total mesorectal excision (LapTME) in patients with mid and low rectal cancer.
Background
Total mesorectal excision (TME) is essential for curative surgery in mid and low rectal cancer, with the quality of dissection impacting recurrence and survival rates. Laparoscopic TME has gained popularity due to its minimally invasive nature, yet challenges remain in achieving optimal outcomes. TaTME was developed to enhance surgical precision and access, particularly in complex cases.
Data Highlights
This study utilized a retrospective cohort design with propensity score matching to assess 3-year oncologic outcomes, including local recurrence, distant metastasis, disease-free survival, and overall survival.
Key Findings
TaTME was performed using a single-team sequential approach, contrasting with LapTME's multi-port laparoscopic technique.
Both surgical approaches were evaluated for local recurrence and overall survival rates.
Early studies indicated potential advantages of TaTME, such as improved distal access and lower conversion rates.
Randomized trials have shown TaTME to be not inferior to LapTME in optimized settings.
Concerns regarding oncologic safety and heterogeneous outcomes have been raised in earlier reports.
Clinical Implications
Surgeons should consider the findings when choosing between TaTME and LapTME.
Conclusion
This study contributes to the understanding of TaTME's effectiveness compared to LapTME.
