Blumgart anastomosis with polyglycolic acid felt reduces the incidence of pancreatic fistula after pancreaticoduodenectomy: A propensity score analysis.

Polyglycolic acid (PGA) felt has been used to prevent clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD). However, there has been no related research on Blumgart anastomosis. Therefore, this study aimed to investigate the practical significance of Blumgart anastomosis with our new method involving PGA felt to prevent CR-POPF following PD. Data from 133 consecutive patients who underwent Blumgart anastomosis during PD between June 2015 and November 2021 were reviewed. We applied PGA felt to 35 of these patients starting from July 2020. Surgical outcomes were analyzed by propensity score matching. Thirty-five (35.7%) of the 98 patients in the without-PGA group were matched with an equal number from the with-PGA group after adjusting for covariates. CR-POPF was found in 17 patients (49%) in the without-PGA group and two patients (6%) in the with-PGA group ( < .001). The multivariate analysis results indicated that male sex, pancreatic duct size <3 mm, soft pancreatic texture, and nonuse of PGA were independently associated with CR-POPF after PD. In conclusion, Blumgart anastomosis with our new penetrating method for PGA felt reduces the incidence of CR-POPF after PD.
