Outcomes measured during the surgical admission included in-hospital hemostasis-related complications (bleeding/transfusion; primary outcome), leak, total hospital costs, length of stay (LOS), and operating room time; 30-, 60-, and 90-day all-cause inpatient readmissions were also examined. We used 1:1 cardinality matching to balance the GST and SIG groups on numerous patient and hospital/provider characteristics, allowing a maximum standardized mean difference (SMD) ≤ 0.05 for all matching covariates. Generalized estimating equations (GEE) accounting for hospital-level clustering were used to compare the study outcomes between the GST and SIG groups.Results: Of the 5573 identified cases, there were 491 patients in each group (982 total) after matching. The observed incidence proportion of hemostasis-related complications during the surgical admission was lower in the GST group as compared with the SIG group (3 events/491 [0.61%] vs 11 events/491 [2.24%]; odds ratio [SIG=reference] = 0.28, 95% CI=0.13– 0.60, P=0.0012). Differences between the GST and SIG groups were not statistically significant for leak, total hospital costs, LOS, OR time, and all-cause inpatient readmission at 30, 60, and 90 days.Conclusion: In this retrospective study of 982 matched patients undergoing sleeve gastrectomy, the ECHELON FLEX™ GST system was associated with a lower rate of hemostasis-related complications as compared with the Signia™ Stapling System. Further controlled prospective studies are needed to confirm the validity of this finding.Keywords: sleeve gastrectomy, surgical staplers, bleeding, leak, costRawlins LJohnson BHJohnston SSElangovanraaj NBhandari MCohen RVRheinwalt KPFryrear RRoy SDove Medical Pressarticlesleeve gastrectomysurgical staplersbleedingleakcostMedical technologyR855-855.5ENMedical Devices: Evidence and Research, Vol Volume 13, Pp 195-204 (2020)
