title: Incidence of incisional hernia following emergency abdominal surgery.
abstract: BACKGROUND
  A retrospective study was conducted to determine incidence and predisposing factors of incisional hernia after an emergency midline laparotomy.
  
  
  METHODS
  The study population consisted in 197 patients of whom 138 were followed-up for 2 years after surgery.
  
  
  RESULTS
  An incisional hernia developed in 25 (18.1%) patients at a mean follow-up of 11.2 months. Multivariate analysis showed the importance of age (> 60 years, p < 0.004), obesity (p < 0.008) and occurrence of post-operative wound infection (p < 0.00001) for the development of an incisional hernia. Univariate analysis showed that intestinal occlusion (p < 0.02), peritonitis (p < 0.006), upper abdominal access (p < 0.04) and post-operative wound infection (p < 0.003) in older patients and obesity (p < 0.003) and the presence of a neoplasm (p < 0.006) in younger patients, played a significant role. The comparison between young and old patients showed that upper abdominal access (p < 0.007), interrupted and layered wound closure (p < 0.02 and p < 0.01, respectively) and contamination of the operative field (p < 0.004) played a statistically significant role in older patients.
  
  
  CONCLUSIONS
  The rate of incisional hernia after an emergency midline laparotomy is higher than after elective procedures. However, it could be reduced with proper attention to the suture technique, i.e. mass and continuous suture, better preparation of the operative field and scrupulous sterility throughout the procedure in order to decrease the incidence of post-operative wound infection.
