The meta-analysis only included studies that were conducted after 2000. The primary outcomes were morbidity and mortality. Pooled odds ratios (ORs), weighted mean differences (WMDs) or hazard ratios (HRs) with 95 percent confidence intervals (CIs) were calculated using fixed effects or random effects models. The methodological quality of the included studies was evaluated by the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool.Results: In total, 45 studies were included in this systematic review, and 5 non-randomized comparative studies with 786 patients (TP: 270, PD: 516) were included in the meta-analysis. There were no differences in terms of mortality (OR: 1.44, 95% CI: 0.66–3.16; P=0.36), hospital stay (WMD: −0.60, 95% CI: −1.78–0.59; P=0.32) and rates of reoperation (OR: 1.12; 95% CI: 0.55–2.31; P=0.75) between the two groups. In addition, morbidity was not significantly different between the two groups (OR: 1.41, 95% CI: 1.01–1.97; P=0.05); however, the results showed that the TP group tended to have more complications than the PD group. Furthermore, the operation time (WMD: 29.56, 95% CI: 8.23–50.89; P=0.007) was longer in the TP group. Blood loss (WMD: 339.96, 95% CI: 117.74–562.18; P=0.003) and blood transfusion (OR: 4.86, 95% CI: 1.93–12.29; P=0.0008) were more common in the TP group than in the PD group. There were no differences in the long-term survival rates between the two groups.Conclusion: This systematic review and meta-analysis suggested that TP may not be as feasible and safe as PD. However, TP and PD may have the same efficacy.Keywords: total pancreatectomy, pancreaticoduodenectomy, morbidity, mortality, meta-analysis
