Retrograde Open Mesenteric Stenting Is Associated With Superior Outcomes for Acute Mesenteric Ischemia

Data regarding retrograde open mesenteric stenting (ROMS) for acute ischemia is limited. Outcomes of patients with requiring emergency surgical intervention were evaluated. Retrospective cohort study an procedure was queried from the National Inpatient Sample database (2018-2020). International Classification Diseases, 10th edition, diagnosis and codes used. Groups bypass (BYPASS), superior artery embolectomy (EMBO), ROMS. We utilized t tests, χ2 multivariate regression. A total 898 included: 284 underwent BYPASS, 363 EMBO, 251 There no significant differences in gender or race among groups. Patients undergoing ROMS more likely to be older (70.2 years vs BYPASS 66.8 EMBO 67.2 years; P = .004) had a higher Charlson Comorbidity Index (2.9 2.5 2.6 EMBO; .029). lowest mortality (15.9% 19.7%, 34.5%; < .0001). associated decreased length stay lower hospital charges (P .0001 .0004, respectively). Multivariate regression demonstrated that greater than 50% reduction (odds ratio [OR], 0.43; 95% confidence interval [CI], 0.26-0.71; Open SMA increased (OR, 2.0; CI 1.33-3.01; .001). Myocardial infarction (OR 2.21; CI, 1.17-4.18; .01) (Table). utilization benefit compared other procedures ischemia. Advanced age, myocardial infarction, risk mortality. may offer revascularization setting alone. These data support further evaluation as choice management setting.TableLogistic model interventionCharacteristicOR95% CIP valueRace WhiteRef Black1.140.66-1.99.8158 Hispanic1.130.64-2.02.8538Sex MaleRef Female0.800.56-1.14.2074Procedure BypassRef embolectomy2.001.33-3.01<.0001 ROMS0.430.26-0.71<.0001Myocardial infarction2.211.17-4.18.0142Charlson Index1.050.95-1.15.3305Age1.031.01-1.04.0003Length stay0.930.91-0.95<.0001CI, Confidence interval; MI, infarction; OR, odds ratio; ROMS, stenting; SMA, artery. table new tab
