Background: Postoperative pancreatic fistula (POPF) is one of the most common and serious complications after pancreaticoduodenectomy (PD). To effectively reduce the incidence of POPF, we designed a new type of pancreaticojejunostomy (PJ), which was termed one-half layer PJ with the rear wall of the pancreas reinforced.
Aim: To explore the clinical application value of this new technique.
Methods: We compared 62 patients who had undergone PD by either the traditional duct-to-mucosa anastomoses or the new one-half layer PJ with the rear wall of the pancreas reinforced method at our hospital from May 2015 to September 2019. All 62 patients were operated by the same surgeon experienced in both procedures. We retrospectively analyzed patient characteristics, perioperative outcomes, and surgical results.
Results: There was no significant difference between the two groups in basic information except the postoperative hospital stays, 14.7 ± 5.4 d in the traditional duct-to-mucosa anastomoses group and 12.0 ± 4.2 d in the one-half layer PJ group (P = 0.042). In terms of postoperative complications, the one-half layer PJ group had a lower rate of POPF than the traditional group. The overall number of cases with POPF was 8 (24.2%) in the traditional group and 2 (6.9%) in the one-half layer group (P = 0.017). Additionally, the rate of grades B and C POPF was lower in the one-half layer group (3.4%) compared with that (12.1%) in the traditional group (P = 0.010). One patient died due to hemorrhage caused by severe pancreatic fistula in the traditional group.
Conclusion: One-half layer PJ with the rear wall of the pancreas reinforced is a safe and feasible procedure that can successfully reduce the rate of POPF. It may be a promising technique for PJ after PD.
