  1. Baseline characteristics of all patients that have underwent an emergency laparotomy (N=268) divided in patients who survived (N=223) and patients that deceased (N=45). Significant differences are mean age, gender, and severely injured patients as shown by higher ISS and AIS and vital parameters at presentation. NS = not statistically significant (p>0.10)
