AIM: To propose a modified subclassification of grade B postoperative pancreatic fistula (POPF) based on management approaches in Chinese patients. METHODS: Data of consecutive pancreatoduodenectomy at two hospitals in China from 2013 to 2018 were collected, and outcomes were compared across different groups of POPF. Subclassification of B-POPF was made based on intervention to B1: non-interventional subclass and B2: interventional subclass. RESULTS: A total of 142 of 522 patients had biochemical leaks (BLs) (27.2%), and POPFs developed in 106 of 522 patients (20.3%), with 81 B-POPFs (15.5%) and 25 C-POPFs (4.8%). BL did not differ from the non-fistula condition in almost all outcomes. The differences of outcomes among the non-fistula/BL, B-POPF and C-POPF groups were significant. The prevalence of subclass B1 and B2 was 56.8% (46/81) and 43.2% (35/81), respectively. Compared to the B1 group, patients in the B2 group had worse outcomes, such as post-pancreatectomy hemorrhage (15.2% vs 34.3%, P = .045), biliary fistula (13.0% vs 34.3%, P = .023), postoperative hospital stay (32 vs 39 days, P = .011), and cost ($US28 601.0 vs $US39 314.5, P < .001). CONCLUSION: The recently reported B-POPF subclassification method was modified in Chinese patients according to the intervention, and is more practical, simpler and fits Chinese patients.
