Summary
Laparoscopic sphincter-preserving total mesorectal excision (TME) for rectal cancer demonstrates safe, long-term oncological outcomes comparable to open surgery. This minimally invasive approach offers comparable survival and disease-free survival rates.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Total mesorectal excision (TME) is the standard for rectal cancer resection, achieving low local recurrence rates.
- Long-term oncological outcomes of laparoscopic TME require further investigation.
- Laparoscopic sphincter-preserving TME aims to maintain quality of life while ensuring oncological safety.
Purpose of the Study:
- To evaluate the long-term oncological outcomes of laparoscopic sphincter-preserving TME.
- To compare laparoscopic TME results with historical data from open surgery.
- To assess the safety and efficacy of minimally invasive TME for mid or low rectal cancer.
Main Methods:
- Prospective analysis of 177 patients with mid or low rectal cancer undergoing laparoscopic sphincter-preserving TME with curative intent.
- Study period: March 1999 to March 2009.
- Median follow-up of 49 months.
Main Results:
- Low conversion rate (1%) and no operative mortality.
- Local recurrence observed in 5.1% of patients.
- Overall 5-year survival: 74%; 5-year disease-free survival: 71%.
Conclusions:
- Laparoscopic sphincter-preserving TME is a safe procedure for rectal cancer.
- Long-term oncological outcomes are comparable to open TME.
- Minimally invasive approach provides effective oncological control.
