Abstract Background/Purpose Early drain removal (EDR) based on drain fluid amylase level (DFA) after pancreaticoduodenectomy excluded 15%‐40% patients from EDR because of inappropriate DFA. Methods Of 198 pancreatoduodenectomy cases, we used the first 105 cases as an exploration cohort to construct the optimal criteria for EDR on postoperative day (POD)4 that were applied to the subsequent 93 cases used as the validation cohort. After that, we examined another 142 patients to further assess the efficacy of the new EDR criteria. Results Of the four independent predictors of clinically relevant postoperative pancreatic fistula (CR‐POPF) ([1] soft pancreas, [2] positive drain fluid culture on POD1, and [3] serum C‐reactive protein [CRP] ≥13 mg/dL on POD4) in the exploration cohort, EDR was applied to cases in the validation cohort meeting the [2] and/or [3], enabling 96% (89/93) applicability of EDR. Outcomes were improved in the validation cohort compared to the exploration cohort; CR‐POPF: 8.6% vs 25.7%, P = .005; Dindo‐Clavien grade ≥ 3 complications: 23.7% vs 41.9%, P = .007; and median hospital stay (day): 21 vs 27, P = .005. The subsequent 142 patients showed 92% (131/142) applicability of EDR and 5.6% (8/142) incidence of CR‐POPF. Conclusions Our new criteria for EDR, without DFA, enabled ≥ 90% applicability of EDR and reduced CR‐POPF.
