title: [Risk Factors for Poor Prognosis after Emergency Surgery for Acute Abdomen].
abstract: BACKGROUND
  Risk factors associated with poor outcome were investigated in patients receiving emergency surgery.
  
  
  METHODS
  Patients' characteristics, surgical information, postoperative complication and 30-days mortality were reviewed in 226 adult consecutive patients undergoing emergency abdominal surgery. Postoperative complication was defined as surgical site infection, anastomotic leakage, intraperitoneal abscess and formation or requirement of renal replacement therapy. Multivariate logistic regression was performed to identify the parameters associated with 30-day mortality and postoperative complication.
  
  
  RESULTS
  Mortality rate was 7.1%. Complication occurred in 41.2%. Multivariate logistic regression revealed surgical Apgar score (SAS) as independent predictor of the death. SAS, duration of the surgery and preoperative SOFA were identified as independent predictors of the complication.
  
  
  CONCLUSIONS
  SAS and preoperative SOFA are useful to predict poor prognosis after emergency surgery due to acute abdomen.
