Risks factors for anastomotic leakage in advanced ovarian cancer: A systematic review and meta-analysis.

This systematic review and meta-analysis aimed to summarise the available evidence on the pre- and intra-operative risk factors for anastomotic leakage (AL) after bowel resection and anastomosis for ovarian cancer (OC). We searched online databases from Pubmed, Scopus, ScienceDirect, and Cochrane Library from inception to October 2020. Pre- and intra-operative risk factors for AL were considered as the primary outcomes. Research heterogeneity and bias were evaluated by I The overall AL rate after OC surgery (median ± SD) was 5.3 ± 12% (277 AL on 5178 anastomoses). Thirteen non-randomised studies were included in the meta-analysis enrolling a total of 3274 patients. Pre albumin level ≤ 3 gr/dl, multiple bowel resections and primary cytoreductive surgery were associated with a significantly high risk of AL with a pooled OR of 5.29 (95% CI: 1.51-18.59), OR = 4.4 (95% CI: 1.19-16.66) and OR = 1.71 (95% CI: 1.05-2.77), respectively. Optimal cytoreduction, ASA score, ascites, and protective stoma were not associated with an increased risk of AL. Based on the best available evidence, preoperative albumin level <3 gr/dl, multiple bowel resections and primary cytoreductive surgery were associated with an increased risk for AL after bowel surgery for OC.
