Lymphatic complications are a common occurrence after staging surgery for early-stage ovarian cancer (eEOC). We investigated whether the introduction of minimally invasive surgery influences the risk of developing lymphoceles and lymphorrhea in patients undergoing staging for eEOC. For this purpose, data of consecutive patients affected by eEOC undergoing staging surgery between January 1980 and January 2016 were retrospectively reviewed, and a systematic review and meta-analysis was performed. This systematic review was registered in the International Prospective Register of Systematic Review. Among 341 patients included in the present study, 47 severe postoperative complications occurred (13.7%), including 40 lymphatic complications: 31 symptomatic lymphoceles (9%) and 9 cases of lymphorrhea (2.6%), respectively. Laparoscopic staging correlated with a lower risk of developing any severe lymphatic complications in comparison with open surgery (p =.02). In particular, the laparoscopic approach and para-aortic node involvement were associated with a trend toward lower lymphoceles (odds ratio,.13; 95% confidence interval,.07â2.20; p =.05) and a trend toward higher risk of lymphorrhea developing (odds ratio, 4.02; 95% confidence interval,.93â17.3; p =.06), respectively. In conclusion, the implementation of a minimally invasive approach might result in a slight reduction of lymphatic complications after eEOC staging.
