Abstract Background Non-occlusive mesenteric ischemia (NOMI) has a high mortality rate, but the analyses of preoperative prognostic factors for improving survival in patients suspected of having NOMI are scarce. We aimed to analyze the prognostic factors of preoperative examinations for NOMI. Methods The clinical data of 224 patients with NOMI were retrospectively collected for a multicenter survey. Clinicophysiological factors were compared between the survivors and non-survivors (N = 107/117) and between the operative and non-operative cases (N = 180/44) by univariate analysis using chi-square test and multivariate analysis using Cox proportional hazard models. In the operative cases, the prognostic operative factors were also analyzed. Results The overall mortality rate for NOMI was 52.2%. There were 129 male and 95 female patients. The mean age was 71.23 (14–94) years. Univariate analysis showed that cardiovascular complication, shock, abdominal pain, average blood pressure, systemic inflammatory response syndrome, aspartic aminotransferase, alanine transaminase, creatine phosphokinase, lactate dehydrogenase, base excess, prothrombin time-international normalized ratio, D-dimer, and fibrinogen degradation products were independent prognostic factors. Multivariate analysis showed that average blood pressure and base excess were independent prognostic factors. Among patients undergoing surgery, those with bowel resection had better prognosis than those without bowel resection, but those with long bowel resection had worse prognosis than those with short resection. Additional postoperative treatment was not effective compared with operation alone (P = 0.011). Conclusions Prognostic factors of preoperative examinations for NOMI were average blood pressure and base excess. Patients with long bowel resection should be carefully monitored owing to their poor prognosis.
