Abstract

Background and study aims : Due to their high morbidity and mortality, anastomotic leakage and disruption are still serious problems in colonic surgery. Bowel clamps applied during anastomosis in order to prevent abdominal contamination with colonic contents, may cause microcirculation and perfusion problems and subsequent ischemia-reperfusion injury. Papaverine, a myorelaxant and vasodilatator, and pentoxiphylline, a hemorrheologic agent are used for microcirculation disorders and vascular endothelial growth factor (VEGF) is a stimulator of angiogenesis. With this experimental study, we aimed to measure trace element [copper (Cu) and zinc (Zn)] levels in ischemia-reperfusion injury due to clamps after left colonic anastomosis in rats and show the effects of papaverine and pentoxiphylline on VEGF that stimulates angiogenesis in anastomotic healing.
