Perioperative Blood Adiponectin Dynamics and Systemic Infflamatory Response After Major Colorectal Surgery

Surgical stress after major abdominal surgery in perioperative period causes neuroendocrine, metabolic and imunologic changes in organism with production of proinfflamatory citokines and results with appearance of systemic infflammmatory response syndrome (SIRS). Dysregulated and overrated SIRS in early postoperative period can lead to complications with additional comorbidities, longer hospital stay and poorer outcome. A low grade chronic infflammatory state in obesity and hypoadiponectinemia can enable the cytokine storm and exaggerated /dysregulated SIRS in obese patients after surgery. Obesity according to this knowledge presents independent risk factor for developing more severe systemic infflamatory response syndrome in early postoperative period after major abdominal surgery. Also, chronic intestinal and gut infflamation is leading theory in oncogenesis of colorectal carcinoma according to recent findings. Many studies find low adiponectin levels in patients with colorectal carcinoma compared to healthy population. Obesity and colorectal cancer have infflamation and low adiponectin level as mutual factor which can be the important key in pathophysiology process of colorectal oncogenesis which are extremly complicated , multifactorial and intertwining. Hypothesis: Lower blood adiponectin levels are associated with higher systemic infflamatory response in patients after major abdominal surgery. Major aim of this study is to investigate correlation between perioperative blood levels of adiponectin and clinical signs of systemic infflamation and blood markers of systemic infflamation in patients after major colorectal surgery.
