Abstract

Introduction: Intestinal ischemia and reperfusion can impair anastomotic strength.The purpose of this study was to evaluate the safety of delayed colon anastomosis following remote ischemia-reperfusion (IR) injury.Methods: Rats divided into two groups underwent bilateral groin incisions, however only the study group had femoral artery clamping to inflict IR injury. Twenty-four hours following this insult, the animals underwent laparotomy, incision of the transverse colon and reanastomosis. End points included anastomotic leakage, strength and histopathological features.Results: Anastomotic leak among IR animals (22.2%) was not statistically different in comparison to the controls [10.5% (p = 0.40)]. Anastomotic mean burst pressures showed no statistically significant difference [150.6 ± 15.57 mmHg in the control group vs. 159.9 ± 9.88 mmHg in the IR group (p = 0.64)]. The acute inflammatory process in the IR group was similar to controls (p = 0.26), as was the chronic repair process (p = 0.88). There was no significant difference between the inflammation:repair ratios amongst the two groups (p = 0.67).Conclusion: Primary colon repair is safe when performed 24 hours following systemic IR injury.
