All categorical values equal the median value for the correspondent continuous variable. Continuous variables are reported as median values. Variables with P < 0.1 were then entered in the multiple regression model. Italic values are statistically significant.

LOS: length of stay; L: litre; ST: standard treatment (see text); LS: LigaSure (see text).
