Abstract:
BACKGROUND:Although laparoscopic colorectal cancer resection is an oncologically safe procedure equivalent to open resection,the effects of conversion of a laparoscopic approach to an open approach remain unclear.This study evaluated the cancer characteristic and oncological outcomes associated with conversion of laparoscopic colorectal resection to open surgery. METHOD:We conducted searches on PubMed, EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Trials. We included the literature published until 2018 that examined the impact of laparoscopic conversion to open colorectal resection. Only randomized control trials and prospective studies were included. Each study was reviewed and the data were extracted. Fixed-effects methods were used to combine data, and 95% confidence intervals (CIs) were used to evaluate the outcomes. RESULTS:Twelve studies with 5427 patients were included. Of these, 4672 patients underwent complete laparoscopic resection with no conversion (LAP group), whereas 755 underwent conversion to an open resection (CONV group). The meta-analysis showedsignificant differences between the LAP group and converted (CONV) group with respect to neoadjuvant therapy (P = .002), location of the rectal cancer (P = .01), and recurrence (P = .01). However, no difference in local recurrence (P = .17) was noted between both groups. CONCLUSION:Conversion of laparoscopic to open colorectal cancer resection is influenced by tumor characteristics. Conversion of laparoscopic surgery for colorectal cancer is associated with a worse oncological outcome.
