Article title: "assessment of the effect of the aquamantys® system on local recurrence after hepatectomy for hepatocellular carcinoma through propensity score matching." objective: to assess the effect of the intraoperative application of the aquamantys ® system to treat the hepatic resection margin on local and overall recurrence of hcc.Methods: we retrospectively analyzed 101 patients admitted from november 2016 to june 2018 who underwent hepatectomy using the aquamantys® as hemostatic device, who were matched with 101 patients (control group) using conventional hemostatic devices through psm.Univariate and multivariate analyses of recurrence-free survival (rfs) and local recurrence-free survival (lrfs) were performed using the cox proportional hazard model.Results: there were no significant differences in baseline data and surgical procedures between the two groups.The aquamantys ® group showed less blood loss (p = 0.005) and a lower blood transfusion rate (p = 0.036), while the incidences of postoperative complications of the two groups showed no difference (p = 0.266).Os rates of the aquamantys ® group and the control group were 82.6% and 84.2%, respectively (p = 0.446), and rfs rates were 65.5% and 58.2%, respectively (p = 0.153), with no significant differences.The aquamantys ® group and the control group had two cases and 11 cases of local recurrence, respectively, with lrfs rates of 98% and 87.9%, respectively, in the follow-up period, corresponding to a significant difference (p = 0.011).Multivariate analysis showed that microvascular invasion (mvi), tumor diameter > 5 cm, and the control group were independent risk factors for lrfs.Aqm group: 101 patients, age mean 57 years, 82 male and 10 female adverse effects: 8 patients received a blood transfusion 1 patient experienced bile leakage 1 patient experienced a pleural effusion 2 patients experienced pneumonia 5 patients experienced ascites 1 patient experienced a perioperative biliary fistula without intra-abdominal hemorrhage there were no patient identifiers within the article; therefore, the patients will be reported as a whole and no other records will be created.
