ABSTRACT
AIM:
Anastomosis leakage is one of the most common complications after colorectal surgery. Studies have shown that the incidence of anastomotic leakage is between 0.5-30%. The aim of our study was to investigate the efficacy of local application of of epidermal growth factor (EGF) on colon anastomosis healing. MATERIAL ANDMETHODS:
28 Wistar rats were randomly divided into 4 groups. Sham group, control group, saline injection group, EGF injection group. Anastomosis line was determined as 3 cm distal to ilealcecal junction. The rats were reoperated on the 7th postoperative day. The colon segment was cut out 3 cm proximal and distal to the anastomotic line.The bursting pressure of each removed colon segment was measured and the segments were fixed with 10% formaldehyde for pathology examination. Anastomosis line was stained with hematoxylin eosin and histopathological evaluation was performed. Evaluation parameters were inflammatory cells, fibroblast, angiogenesis (neovascularization) and collagen amounts.RESULTS:
Bursting pressure was higher in the EGF group than in the control group and saline injection group. There was statistically significant difference between EGF and positive control group. (p<0,05) Histopathological examination revealed that the inflammatory cell density was higher in the positive control group than in the other groups. Fibroblast cell density, neovascularization and collagen content were higher in EGF group than the others. However, no statistically significant difference was found between the control group,saline injection group and EGF injection group.CONCLUSION:
As result of our study,we think that local application of EGF may have a positive effect on healing of colon anastomosis. KEY WORDS Colonic Anastomosis, Egf, Experimental, Healing.
