Abstract

Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopic colorectal surgery (LCRS) and conventional open surgery (OCRS) for colorectal cancer (CRC).

Methods: We searched relevant papers published between January 1990 and May 2011. We analyzed the outcomes of each type of surgery over the short- and long-term periods.

Results: In the short-term period, we found no significant differences in overall perioperative complications and anastomotic leakage between LCRS and OCRS groups. We found no significant differences in overall, distant, local and wound-site recurrence, overall mortality, 3 and 5 year disease-free survival rate, and cancer-related mortality between the 2 groups.

Conclusions: LCRS has the benefits of reducing intraoperative blood loss, earlier resumption of oral intake, and shorter duration of hospital stay in the short-term. The long-term outcomes of LCRS seem to be similar to those of OCRS.
