Randomized clinical trial of laparoscopic versus open left colonic resection

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Colorectal Surgery

Background:

• Comparison of surgical techniques for left colonic resection is crucial for optimizing patient outcomes.
• Evaluating both short-term and long-term results is essential for determining the preferred surgical approach.

Purpose of the Study:

• To compare short-term results and long-term outcomes of laparoscopic versus open left colonic resection.
• To assess cost-benefit, quality of life, long-term morbidity, and 5-year survival rates.

Main Methods:

• Randomized controlled trial involving 268 adult patients undergoing elective left colonic resection.
• Patients were assigned to either laparoscopic (n=134) or open (n=134) surgery with identical postoperative care protocols.
• Evaluated parameters included morbidity, hospital stay, cost-benefit, quality of life, and 5-year survival.

Main Results:

• Laparoscopic surgery showed a trend towards lower short-term morbidity (11.9% vs 20.1%) and significantly shorter hospital stays (7.0 vs 8.7 days).
• Quality of life improved significantly at 6 months post-laparoscopic surgery, with no subsequent differences.
• Long-term morbidity (7.5% vs 11.9%) and 5-year cancer survival rates (72% vs 66%) were similar between laparoscopic and open groups, respectively.

Conclusions:

• Laparoscopic left colonic resection facilitates an earlier recovery period for patients.
• Given similar cost-benefit analyses and long-term follow-up results, the laparoscopic approach is favored over open surgery.
