  1. Analysis of the correlation between complications and length of stay (logarithmic transformed) in a multivariate stepwise (removal if p ≥ 0.1) linear regression. Following was removed from the model: Total complications (p = 0.9), bleeding (p = 0.6), other surgical (p = 0.5), wound (p = 0.6), other medical (p = 0.3), anemia (p = 0.1) and gastrointestinal complications (p = 0.1). Length of stay was defined as time from surgery to discharge. OR odds ratio
