Fig. 4. Wet/Dry (W/D) ratio of (  A ) healthy colon (  P = 0.94), (  B ) perianastomotic colon (  P = 0.62), and (  C ) lung tissue after 4 h of treatment (  P = 0.03). Group R-RL (restricted Ringer lactate) received 3 ml · kg⁻¹· h⁻¹Ringer lactate (RL); Group GD-RL (goal-directed RL) received 3 ml · kg⁻¹· h⁻¹RL + 250 ml of RL if Svo²was less than 60%; Group GD-C (goal-directed colloid) received 3 ml · kg⁻¹· h⁻¹RL + 250 ml of hydroxyethyl starch (HES; 130/0.4) if Svo²was < 60%. No statistically significant differences between the groups were detected in panels  A and  B . Significant differences in panel  C (  P < 0.05) for ANOVA (Tukey  post hoc test): *= R-RL  vs. GD-RL, ≠= R-RL  vs. GD-C.
