Objective:

To establish the safety and feasibility of combining delayed coloanal anastomosis (DCAA) with transanal total mesorectal excision (taTME) for high-risk low rectal cancer patients, focusing on primary outcomes such as anastomotic leakage rates and recovery times.

Key Findings:

• DCAA-taTME may reduce anastomotic leakage rates compared to ICAA-taTME, which is significant for improving patient outcomes.
• The study emphasizes the importance of patient selection and surgical technique in high-risk cases.
• DCAA allows for improved tissue repair by delaying anastomosis.

Interpretation:

The findings suggest that DCAA-taTME could be a safer alternative to ICAA-taTME in high-risk low rectal cancer patients, potentially lowering complications associated with anastomotic leakage and improving overall surgical outcomes.

Limitations:

• Limited sample size may affect the generalizability of the results.
• The study is observational and lacks randomization, which may introduce selection bias.

Conclusion:

Combining DCAA with taTME shows promise in improving surgical outcomes for high-risk low rectal cancer patients, warranting further investigation.
