Abstract:
Objective To evaluate the efficacy and safety of the unilateral and bilateral drainage in hilar malignant biliary obstruction with a meta?analysis of relevant studies. Methods A systematic electronic search with keywords “ biliary stent”, “hilar tumor” and “malignant biliary obstruction” was independently performed by two reviewers in major electronic databases of Pubmed, EMBASE, Cochrane Library and Web of Science. A meta?analysis was conducted using Revman 5?? 1 software. Results Six studies were included with a total number of 558 patients, of whom 307 patients underwent unilateral biliary drainage and 251 pa?tients bilateral drainage. There was no significant difference in early complications ( OR = 1?? 03,95% CI:0?? 58?1?? 81,P = 0?? 93), later complications (OR = 0?? 98,95%CI:0?? 46?2?? 07,P = 0?? 95), operation success rate (OR= 1?? 42,95%CI:0?? 76?2?? 66,P = 0?? 28),drainage efficacy or median survival time between the two groups. Compared with unilateral biliary drainage, bilateral biliary drainage had a longer time of stent patency (MD = - 29?? 12,95% CI:- 38?? 55?- 19?? 70,P< 0?? 001). Conclusion Both unilateral and bilateral biliary drainage are safe and effective for hilar malignant biliary obstruction, but more high quality clinical researches are needed.
