Right versus left laparoscopic colectomy for colon cancer: does side make any difference?

Area of Science:

• Colorectal surgery
• Minimally invasive surgery
• Surgical oncology

Background:

• Laparoscopic colectomy is a standard treatment for colon cancer.
• Comparing outcomes between right and left laparoscopic colectomy is essential for optimizing patient care.

Purpose of the Study:

• To compare intraoperative and postoperative outcomes between right laparoscopic colectomy (RLC) and left laparoscopic colectomy (LLC) for colon cancer.

Main Methods:

• A retrospective analysis of 547 patients undergoing elective RLC or LLC for colon cancer between 2004 and 2014.
• Primary outcomes included technical difficulty (operative time, complications, conversion) and postoperative outcomes (complications, length of stay, reinterventions, readmissions, mortality).

Main Results:

• RLC patients were older with more comorbidities. Operative time was shorter for RLC (162 vs. 185 min).
• No significant differences in intraoperative complications or conversion rates were observed.
• RLC was associated with higher overall morbidity (20.5% vs. 13.3%), increased ileus (10.6% vs. 2.4%), and longer hospital stay (4.7 vs. 3.9 days).

Conclusions:

• Right laparoscopic colectomy for colon cancer is independently associated with a shorter operative time, increased risk of postoperative ileus, and a longer hospital stay compared to left laparoscopic colectomy.
• These findings are significant for high-volume centers when selecting surgical approaches for colon cancer.
