Abstract
OBJECTIVE: To investigate the advantage between isolated Roux loop pancreaticojejunostomy (IPJ) and conventional pancreaticojejunostomy (CPJ) after pancreaticoduodenectomy (PD). METHODS: Comparative studies on this topic published between January 1976 and April 2015 in PubMed, EMbase, EBSCO, Science Citation Index Expanded and Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library were searched, and selected based on specific inclusion and exclusion criteria. Perioperative outcomes such as postoperative pancreatic fistula, delayed gastric emptying, operation time, intraoperative blood loss, intraoperative blood transfusion, postoperative bleeding, intra-abdominal abscess, bile leakage, wound infection, morbidity and mortality were compared. Pooled odds ratios (OR) or weighted mean differences (WMD) with 95% confidence interval (CI) were calculated using either fixed- or random-effects model. RESULTS: Six studies were included with two randomized controlled and four nonrandomized trials. A total of 712 patients (359 patients from the IPJ group and 353 patients from the CPJ group) were analyzed. The pooled results revealed that IPJ had longer operation time (WMD = 36.55, 95% CI 6.98 to 66.11, P = 0.02). However, there were no significant differences between both groups in postoperative pancreatic fistula, intraoperative blood loss, blood transfusion, delayed gastric emptying, postoperative bleeding, intra-abdominal abscess, bile leakage, wound infection, morbidity, mortality and postoperative hospital stay. CONCLUSIONS: PD with IPJ was comparable to CPJ in intraoperative outcomes and postoperative complications. However, further randomized controlled trials should be undertaken to ascertain these findings.
