Background
To date, no large-scale study has been undertaken to understand the clinical features of non-occlusive mesenteric ischemia (NOMI) after surgery. We thus performed a multicenter investigation to clarify the clinical outcomes and prognostic factors of NOMI.
Patients and Methods
Clinical databases from 22 Japanese facilities were reviewed for evaluation of patients who received surgery for NOMI between 2004 and 2012. NOMI patients (n = 51) were divided into two groups: group I (n = 28) consisted of patients who survived, and group II (n = 23) consisted of patients who did not survived. Prognostic factors were compared between the two groups.
Results
NOMI surgery represented 0.04 % of the total number of operations performed in this time period. The overall mortality rate for NOMI surgery was 45 %. Hemodialysis was a significant negative prognostic factor (p = 0.027). Preoperative elevation of transaminases, potassium, and white blood cell count, as well as metabolic acidosis and colon ischemia was poor prognostic factors. The mean Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) score of group I versus group II was 54.5 ± 3.6 and 85.2 ± 4.1, respectively (p < 0.001).
Conclusions
Currently, NOMI surgery has a 45 % mortality rate. POSSUM scores can be used to predict the clinical outcome of patients who receive NOMI surgery.
