Laparoscopic rectal surgery for middle and lower rectal cancer

Area of Science:

• Colorectal surgery
• Surgical oncology
• Minimally invasive surgery

Background:

• The efficacy of laparoscopic low anterior resection (LAR) for middle and lower rectal cancer is debated.
• Evaluating LAR's outcomes is crucial for treatment planning.

Purpose of the Study:

• To assess the short- and long-term outcomes of laparoscopic low anterior resection (LAR) for middle and lower rectal cancer.
• To determine the feasibility of LAR in treating advanced rectal cancers.

Main Methods:

• Retrospective analysis of 98 patients undergoing laparoscopic rectal surgery with total mesorectal excision.
• Classification of tumors based on distance from the anal verge (<8 cm or ≥8 cm).
• Detailed recording of operative variables, complications, and survival rates.

Main Results:

• Mean operative time was 236 minutes with 147g blood loss; 5 conversions to open surgery were required.
• Postoperative complications included 13.1% anastomotic leakage and 32.2% overall morbidity, with no operative deaths.
• 5-year survival rates ranged from 55.1% to 95.7% depending on cancer stage.

Conclusions:

• Laparoscopic low anterior resection (LAR) provides acceptable short- and long-term outcomes for rectal cancer.
• LAR is a valuable surgical option, even for advanced lower rectal cancer cases.
• Minimally invasive techniques in rectal cancer surgery show promising results.
