Abstract
PURPOSE To evaluate the effects of shared decision-making (SDM) with patient decision aid (PtDA) on hemostasis device selection and reduction of decisional conflicts in patients undergoing transfemoral angiography. MATERIALS AND METHODS Patients undergoing angiography were randomized to receive either a standard explanation or the process aid of PtDA for choosing hemostasis devices. The decisional conflict was assessed using the 4-item SURE (Sure of myself; Understand information; Risk-benefit ratio; Encouragement) scale. Differences in demographic variables, clinical variables, and final choice of hemostasis devices were compared through univariable and multivariable logistic regression analyses. RESULTS In total, 158 patients were included-80 in the PtDA group and 78 in the standard group. No difference was found between the two groups in terms of patient demographic and clinical variables. The PtDA group scored better on all questions of the SURE scale both individually and collaboratively (P < .001). PtDA intervention (P = .031) and the reason for angiography (P = .0006) were the main variables that influenced patient hemostasis device choice in the univariable logistic regression analysis. Reason for angiography remained the only deciding factor that affected patient choice in multivariable logistic regression analysis (P = .015). CONCLUSIONS Step-by-step guidance and pictorial explanation with the assistance of PtDA led to improvements in patient knowledge but show no significant impact in multivariate analysis for the influence on the choice of hemostasis device. Implementation of PtDA-aided SDM is recommended for improving patient-centered care.

Abstract
BACKGROUND Complications including staple-line leakage and bleeding may occur after sleeve gastrectomy and Roux-en-Y gastric bypass. In this meta-analysis, the efficacy of fibrin sealant in strengthening the staple line and reducing complication risk after bariatric surgery was evaluated. METHODS We searched PubMed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs) published up to October 2020. Pooled estimates of the outcomes were computed using a random effects model. The primary outcomes were bleeding and leakage; secondary outcomes were gastric stricture, length of hospital stay, reoperation rate, and total operation time. RESULTS In total, 9 RCTs including 2136 patients were reviewed. Our meta-analysis revealed that compared with controls, fibrin sealants decreased incidence of bleeding significantly (risk ratio [RR] = 0.42; 95% confidence interval [CI], 0.18-0.97), but did not demonstrate significant differences in reducing the incidence of leakage (RR = 0.62; 95% CI, 0.23-1.73), gastric stricture (RR = 1.16; 95% CI, 0.46-2.91), reoperation rate (RR = 0.85; CI, 0.14-5.14), or length of hospital stay (weighted mean difference = 0.62; 95% CI, - 0.31 to 1.55). Compared with oversewing, fibrin sealant use reduced the operation time; however, their efficacies in reducing the incidence of postoperative bleeding and leakage did not differ significantly. CONCLUSIONS Although applying fibrin sealants to the staple line in bariatric surgery may provide favorable results, but it may not reduce postoperative leakage and stricture incidence significantly. Nevertheless, the application of fibrin sealants as a method for reducing risks of complications after bariatric surgery warrant further investigation.
