Abstract:

Objective

To systematically evaluate the effect of preoperative biliary drainage (PBD) on the postoperative complications after pancreaticoduodenectomy (PD).

Methods

Literatures published between January 2009 to December 2019 were retrieved in PubMed, Web of Science, Embase, the Cochrane Library, Ovid Journals, CNKI, Wanfang Data and Chongqing VIP databases with the keywords of preoperative biliary drainage, obstructive jaundice, pancreaticoduodenectomy, pancreatic head cancer, periampullary malignancy, biliary stricture. Clinical data such as incidence of postoperative pancreatic fistula, bile leakage, delayed gastric emptying, operative area infection and abdominal infection of PBD and non-PBD groups (N-PBD group) were extracted and subjected to Meta-analysis.

Results

A total of 23 articles consisting of 6 537 patients were included. 3 479 cases were assigned in PBD group and 3 058 cases in N-PBD group. Meta-analysis showed that the incidence of pancreatic fistula in PBD group was 14.92%(505/3 385), significantly higher than 11.78%(359/2 964) in N-PBD group (OR=1.19, 95%CI:1.02-1.38, P=0.03). The incidence of delayed gastric emptying in PBD group was 13.40%(288/2 150), significantly higher than 11.72%(217/1 851) in N-PBD group (OR=1.25, 95%CI:1.03-1.52, P=0.02). The incidence of operative area infection in PBD group was 14.97%(480/3 207), significantly higher than 6.78%(189/2 789) in N-PBD group (OR=2.57, 95%CI:2.14-3.09, P<0.001). The incidence of bile leakage, abdominal infection, bleeding, cardiopulmonary complications, secondary operation and mortality did not significantly differ between two groups (P>0.05).

Conclusions

Routine PBD fails to bring significant benefits to patients with obstructive jaundice undergoing PD, whereas it increases the incidence of pancreatic fistula, delayed gastric emptying and operative area infection.
