title: Factors affecting morbidity and mortality in incarcerated abdominal wall hernias.
abstract: BACKGROUND
  Incarcerated abdominal wall hernia cases may necessitate emergency interventions, but under such circumstances morbidity and mortality rates may increase. The aim of this study was to investigate the factors that affect morbidity and mortality in patients with incarcerated abdominal wall hernias who underwent emergency surgery.
  
  
  METHODS
  Urgent surgical interventions due to incarcerated abdominal wall hernias were performed in 182 patients in our clinics between January 1998 and January 2006. Factors that affect morbidity and mortality in incarcerated abdominal wall hernias were investigated retrospectively by browsing the archives. Logistic regression analysis was used to evaluate parameters that affect morbidity and mortality.
  
  
  RESULTS
  Morbidity and mortality occurred in 43 (23.6%) and 9 (4.9%) patients, respectively. A symptomatic period of longer than 8 h, presence of accompanying disease, high American Society of Anesthesiology (ASA) score, general anesthesia, presence of strangulation, and necrosis were found to affect morbidity significantly by univariate analysis. Necrosis was the sole factor affecting morbidity significantly by multivariate analysis. Advanced age, presence of accompanying disease, high ASA score, presence of strangulation, necrosis, and hernia repair with graft were found to affect mortality significantly by univariate analysis; however, necrosis was the sole factor affecting mortality significantly by multivariate analysis.
  
  
  CONCLUSIONS
  Intestinal necrosis, which was followed by bowel resection, was the sole factor affecting morbidity and mortality using multivariate logistic regression analysis. Emergency surgery is required for incarcerated abdominal wall hernias before intestinal necrosis develops.
