Emergencies on direct oral anticoagulants: Management, outcomes, and laboratory effects of prothrombin complex concentrate

Background In the initial absence of specific reversal agents for factor Xa inhibitors (FXa-Is), prothrombin complex concentrate (PCC) as a hemostatic agent has been recommended by guidelines. Since 2017, idarucizumab has been registered for dabigatran reversal. Still, data on the clinical outcome of direct oral anticoagulant (DOAC)-related emergencies (major bleeding or urgent interventions) is scarce. In addition, it is unknown to what extent PCC restores thrombin generation in FXa-I-related emergencies. Our aim was to describe management and clinical outcomes of DOAC-related emergencies and to assess the laboratory effect of PCC in patients with FXa-I emergencies. Methods In this prospective cohort study in 5 Dutch hospitals, patients presenting with DOAC-related emergencies were eligible. The primary outcome was effective hemostasis according to the ISTH definition. Safety outcomes were 30-day mortality and thromboembolic rate. In patients treated with PCC, additional blood samples were taken to assess the effect on thrombin generation. Results We included 101 patients with major bleeding (FXa-I, 76; dabigatran, 25) and 21 patients requiring an urgent intervention (FXa-I, 16; dabigatran, 5). Of patients with major bleeding, 67% were treated with PCC or idarucizumab. Effective hemostasis, 30-day mortality, and thromboembolism rate were 67%, 22%, and 1%, respectively. In a subset of bleeding patients on FXa-I managed with PCC, thrombin generation increased, with 96% immediately after PCC administration. In patients requiring an urgent intervention, effective hemostasis, 30-day mortality, and thromboembolic rate were 95%, 14%, and 5%. Conclusions Effective hemostasis was achieved in the majority of patients presenting with DOAC-related emergencies;, thromboembolic complications were rare, and mortality was quite high

The diagnostic value of staging laparoscopy in gallbladder cancer: a nationwide cohort study

Abstract Background Disseminated disease (DD) is often found at (re-)exploration in gallbladder cancer (GBC) patients. We aimed to assess the yield of staging laparoscopy (SL) and identify predictors for DD. Methods This retrospective study included patients from all Dutch academic centres with primary GBC (pGBC) and incidentally diagnosed GBC (iGBC) planned for (re-)resection. The yield of SL was determined. In iGBC, predictive factors for DD were assessed. Results In total, 290 patients were included. Of 183 included pGBC patients, 143 underwent laparotomy without SL, and 42 (29%) showed DD perioperatively. SL, conducted in 40 patients, identified DD in eight. DD was found in nine of 32 patients who underwent laparotomy after SL. Of 107 included iGBC patients, 100 underwent laparotomy without SL, and 19 showed DD perioperatively. SL, conducted in seven patients, identified DD in one. Cholecystitis (OR = 4.25; 95% CI 1.51–11.91) and primary R1/R2 resection (OR = 3.94; 95% CI 1.39–11.19) were independent predictive factors for DD. Conclusions In pGBC patients, SL may identify DD in up to 20% of patients and should be part of standard management. In iGBC patients, SL is indicated after primary resection for cholecystitis and after initial R1/R2 resection due to the association of these factors with DD
