Background/objectives: This study aimed to assess the outcomes and characteristics of post-pancreatectomy hemorrhage (PPH) in over 1000 patients who underwent pancreatoduodenectomy (PD) at a high-volume hepatopancreaticobiliary center.
Methods: This retrospective study analyzed consecutive patients who underwent PD from 2010 through 2021. PPH was diagnosed and managed using our algorithm based on timing of onset and location of hemorrhage.
Results: Of 1096 patients who underwent PD, 33 patients (3.0%) had PPH; incidence of in-hospital and 90-day mortality relevant to PPH were one patient (3.0%) and zero patients, respectively. Early (≤24 h after surgery) and late (>24 h) PPH affected 9 patients and 24 patients, respectively; 16 patients experienced late-extraluminal PPH. The incidence of postoperative pancreatic fistula (p < 0.001), abdominal infection (p < 0.001), highest values of drain fluid amylase (DFA) within 3 days, and highest value of C-reactive protein (CRP) within 3 days after surgery (DFA: p < 0.001) (CRP: p = 0.010) were significantly higher in the late-extraluminal-PPH group. The highest values of DFA≥10000U/l (p = 0.022), CRP≥15 mg/dl (p < 0.001), and incidence of abdominal infection (p = 0.004) were identified as independent risk factors for PPH in the multivariate analysis. Although the hospital stay was significantly longer in the late-extraluminal-PPH group (p < 0.001), discharge to patient's home (p = 0.751) and readmission rate within 30-day (p = 0.765) and 90-day (p = 0.062) did not differ between groups.
Conclusions: Standardized management of PPH according to the onset and source of hemorrhage minimizes the incidence of serious deterioration and mortality. High-risk patients with PPH can be predicted based on the DFA values, CRP levels, and incidence of abdominal infections.
