Is Percutaneous Transhepatic Biliary Drainage Better than Endoscopic Drainage in the Management of Jaundiced Patients Awaiting Pancreaticoduodenectomy? A Systematic Review and Meta-analysis

Abstract

Purpose: To compare postoperative complications in patients who underwent pancreatoduodenectomy after either endoscopic or percutaneous biliary drain (BD).

Material and methods: Data from studies comparing the rate of postoperative complications in patients who underwent endoscopic BD or percutaneous BD before pancreatoduodenectomy were extracted independently by 2 investigators. The primary outcome compared in the meta-analysis was the risk of postoperative complications. Secondary outcomes were the risks of procedure-related complications, postoperative mortality, postoperative pancreatic fistula, severe complications, and wound infection. For dichotomous variables, the odds ratio (OR) with 95% confidence interval (CI) was calculated.

Results: Thirteen studies, including 2334 patients (501 in the percutaneous BD group and 1833 in the endoscopic group), met the inclusion criteria. Postoperative and procedure-related complication rates were significantly lower in the percutaneous BD group (OR = .7, 95% CI = .52-.94, P = .02 and OR = .44, 95% CI = .23-.84, P = .01, respectively). No significant differences were observed when severe postoperative complications, postoperative mortality, postoperative pancreatic fistula, and wound infection rates were compared.

Conclusions: In patients awaiting pancreatoduodenectomy, preoperative percutaneous BD is associated with fewer procedure-related or postoperative complications than endoscopic drain.
