Abstract:

Background and objective: The last randomized controlled trials ,the ACOSOG Z6051 1,2 and the ALaCaRT trial3, 4 could not show the non-inferiority of the laparoscopy in comparison to laparotomy for rectal cancer. In fact, the ten first years of practicing laparoscopy were years when surgeons developed their learning curve. Therefore, by excluding this learning bias, it is possible to end up with a more fair and correct comparison between the two techniques. It is henceforth relevant to pursue a new meta-analysis that compares the two techniques and excludes studies done during the earlier periods of laparoscopic rectal surgery. Results: Six randomized controlled trials met the eligibility criteria, involving a total of 1556 patients in the laparoscopy group and 1188 patients in the laparotomy group. Our meta-analysis was in favor of laparoscopy in a significant way for blood loss, first bowel movement and the number of harvested lymph nodes. It was non-significantly in favour of laparoscopy for 30-days mortality after surgery and length of hospital stay. It was significantly in favor of laparotomy for operative duration. No significant difference was found in anastomotic leakage) , reoperation within 30 days, number of positive CRMs and completeness of mesorectal excision between the two groups. No difference was found in recurrence, disease-free survival and overall survival between laparoscopy group and laparotomy group. Conclusion: The comparison of the randomized controlled trials published before and after 2010, showed no significant difference in outcomes between the learning period and after.
