Objective   To compare the intraoperative and postoperative outcomes of central pancreatectomy (CP) with distal pancreatectomy (DP).Methods   A systematic literature search was performed on electronic databases from MEDLINE, Embase, and PubMed from 1998 to 2018. Statistical analysis and meta-analysis were performed using statistics/data analysis (Stata®) software, version 12.0 (StataCorp LP, College Station, Texas 77845, USA). Dichotomous variables were analyzed by estimation of relative risk (RR) with a 95 percent (%) confidence interval (CI) and continuous variables were analyzed by standardized mean differences (SMD) with 95% CI.Results   Twenty-four studies with 593 CP and 1226 DP were included in the meta-analysis. CP had significantly longer operation time (SMD: 1.03; 95% CI 0.62 to 1.44;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.001) and lengthier postoperative hospital stay (SMD: 0.63; 95% CI 0.20 to 1.05;  P  < 0.01). Estimated blood loss was significantly lower in CP (SMD: −0.34; 95% CI −0.58 to −0.09;  P  = 0.007). Overall postoperative morbidity (RR: 1.30; 95% CI: 1.13 to 1.50;  P  < 0.001), overall pancreatic fistula (RR: 1.41; 95% CI: 1.20 to 1.66;  P  < 0.001), clinically relevant fistula (RR: 1.64; 95% CI: 1.25 to 2.16;  P  < 0.001), and postoperative hemorrhage (RR: 1.90; 95% CI: 1.18 to 3.06;  P  < 0.05) were all significantly higher after CP. On long-term follow-up, DP patients were more likely to have postoperative exocrine (RR: 0.56; 95% CI: 0.37 to 0.84;  P  < 0.05) and endocrine (RR: 0.27; 95% CI: 0.18 to 0.40;  P  < 0.001) insufficiency. There was no statistically significant difference in transfusion requirement, postoperative mortality, reoperation, and tumor recurrence.Conclusion   CP is associated with significantly higher morbidity and clinically relevant pancreatic fistula. CP should only be reserved for selected patients who require postoperative pancreatic function preservation.
