Introduction:
Postoperative pancreatic fistula (POPF) is the most severe complication after pancreaticoduodenectomy (PD), and this study investigates the effects of single-layer and double-layer pancreaticojejunostomy (PJ) on POPF.
Evidence Acquisition:
Four electronic databases were systematically searched until March 2024: PubMed, Web of Science, Embase, and Cochrane Library. Statistical analysis was performed using Review Manager (RevMan) software. Mean difference (MD) or odds ratios (OR) with 95% confidence intervals (CI) were used to indicate continuous or dichotomous variables, respectively. Ten studies were included, comprising 1811 patients.
Evidence Synthesis:
Compared to the double-layer PJ group, the single-layer PJ group had a similar POPF rate (OR=0.73; P=0.28) and grade C POPF rate (OR=0.55; P=0.12), but a lower grade B POPF rate (OR=0.50; 95% CI: 0.31-0.81; P=0.005). The clinically relevant POPF (CR-POPF) rate was lower in the single-layer PJ group (OR=0.47; 95% CI: 0.31-0.73; P<0.001), especially in the 2017 International Study Group of Pancreatic Surgery (ISGPS) criteria subgroup (OR=0.44; 95% CI: 0.27-0.73; P=0.001), the China subgroup (OR=0.41; 95% CI: 0.26-0.64; P<0.001), and the minimally invasive subgroup (OR=0.40; 95% CI: 0.22-0.74; P=0.003).
Conclusions:
Compared with double-layer PJ, single-layer PJ after PD might reduce the incidence of CR-POPF.
