BackgroundThe role of preoperative biliary drainage (PBD) for hilar cholangiocarcinoma (HCC) remains unclear. The aim of this meta-analysis is to investigate the role of PBD in the treatment of potentially resectable HCC.MethodsAll studies reporting outcomes on patients with PBD vs without PBD were included. A systematic literature search was performed in PubMed, Embase, and the Cochrane Library for studies published between 1980 and 2016.ResultsInitial search identified 667 articles. Only 9 studies met the inclusion criteria and were included in this analysis. No significant differences in mortality were observed between the two groups (RR = 0,935; 95% CI = 0,612 to 1429; p = 0,463). Overall morbidity was significantly higher in PBD group (RR = 1266; 95% CI = 1039 to 1543; p = 0,011). No significant differences in transfusion rate, hospital stay, anastomotic leaks, abdominal collections and operative time, were found. Wound infections were significantly higher in PBD group.ConclusionsPBD seems to be associated with higher postoperative morbidity and increases the risk of wound infections. Further prospective studies are needed to better define the impact of PBD in outcomes after surgery for hilar cholangiocarcinoma.
