AbstractBackground and Aim:
To compare percutaneous transhepatic biliary drainage (PTBD) and endoscopic biliary drainage (EBD) for management of malignant biliary tract obstruction (MBTO).Methods:
PubMed, Google Scholar, and the Cochrane database were searched to 31 December 2013. Main outcome measurements were therapeutic success rate, 30-day mortality rate, overall complications, cholangitis, and pancreatitis.Results:
Eight studies (five retrospective and three randomized controlled trials) were included in the meta-analysis with a total of 692 participants. Combined odds ratio (OR) = 2.18 revealed no significant difference in therapeutic success between PTBD and EBD (95% confidence interval [CI] = 0.73–6.47, P = 0.162). However, after excluding two studies that appeared to be outliers, PTBD exhibited a better therapeutic success rate than EBD (pooled OR = 4.45, 95% CI = 2.68–7.40, P < 0.001). Patients who underwent PTBD were 0.55 times as likely to have cholangitis as those who underwent EBD, whereas the overall complication rate, pancreatitis rate, and 30-day mortality were similar between the two procedures.Conclusions:
PTBD may be associated with a better therapeutic success rate and lower incidence of cholangitis than EBD, but the overall complication rate, pancreatitis rate, and 30-day mortality of the two procedures are similar.
