Objective To systematically review the effect of laparoscopy versus laparotomy for borderline ovarian tumors (BOTs) on postoperative recurrence. Methods We searched PubMed, The Cochrane Library (Issue 11, 2015), EMbase, Web of Science, CNKI, WanFang Data and CBM databases from inception to Nov. 2015, to collect relevant clinical studies comparing laparoscopy and laparotomy for BOTs. Two reviewer independently screened literature, extracted data and assessed the risk of bias of include studies by using NOS scale. Then, meta-analysis was performed by using RevMan 5.3 software. Results Nineteen cohort studies were included. The scores of NOS scale showed that 10 studies were < 7 points, while the other 9 studies were≥7 points. The results of meta-analysis showed that: the recurrence rate of tumor (OR=1.75, 95%CI 1.05 to 2.91, P=0.03) in the laparoscopy group was higher than that in the laparotomy group, but no significant differences were found in further subgroup analysis according to type of operations (conservative surgery: OR=1.22, 95%CI 0.71 to 2.08, P=0.47; non-conservative surgery: OR=4.38, 95% CI 0.85 to 22.68, P=0.08). The diameter of tumor in the laparoscopy group was significant smaller than that in the laparotomy group (MD=-6.88, 95% CI-8.15 to-5.61, P < 0.000 01), and the rate of rupture of tumor in the laparoscopy group was significant higher than that in the laparotomy group (OR=3.99, 95% CI 2.54 to 6.26, P < 0.000 01). Conclusion Current evidence shows, compared with laparotomy, laparoscopy has similar effect on postoperative recurrence and smaller diameter of tumor, but laparoscopy could increase the rate of rupture of tumor. Due to the limited quality and sample size of included studies, more high quality and large sample size studies are need to prove the above conclusion.
