Summary
The modified Bacon procedure for low rectal cancer shows lower costs and fewer complications like anastomotic leakage compared to the double stapling technique (DST). While initial functional recovery may be slower, long-term survival outcomes are similar for both sphincter-preserving surgical methods.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Gastrointestinal Oncology
Background:
- Sphincter-preserving surgery for low rectal cancer presents significant challenges.
- The double stapling technique (DST) and modified Bacon procedure are common approaches, but comparative data on outcomes is limited.
Purpose of the Study:
- To compare the modified Bacon procedure and DST in terms of postoperative functional recovery, complication rates, and survival in patients with low rectal cancer.
Main Methods:
- Retrospective cohort study of 110 patients undergoing low rectal cancer surgery.
- Patients were divided into modified Bacon procedure (n=43) and DST (n=67) groups.
- Analysis included perioperative data, complications, Wexner scores, and 3-year disease-free survival (DFS) and overall survival (OS).
Main Results:
- The modified Bacon procedure was associated with lower hospital costs and significantly reduced rates of anastomotic leakage and prophylactic stoma use compared to DST.
- Higher Wexner scores (indicating poorer function) were observed with the modified Bacon procedure at 3 and 6 months postoperatively, but not at 12 months.
- No significant differences in 3-year DFS or OS were found between the two surgical techniques.
Conclusions:
- The modified Bacon procedure appears to be a feasible sphincter-preserving option for low rectal cancer, demonstrating advantages in cost and complication rates.
- While functional recovery may show initial differences, long-term oncological outcomes are comparable to DST.
- Further validation through prospective studies is recommended to confirm the role of the modified Bacon procedure.
