In the last few years it was performed in cases with complicated inflammation of the left colon, colon cancers with bowel obstruction or perforation, or in the case of insufficiency of the anastomoses, or in urgent operations after traumatics bowel injuries, when making the anastomosis is at very high risk.

Is small for gestational age status associated with an increased risk of atherogenesis?

Abstract: The "catch-up growth" phenomenon in children born small for gestational age (SGA) has been linked to early onset obesity with the subsequent emergence of metabolic syndrome (MetS). The intima media thickness of the common carotid artery (CIMT) is a well-known marker of subclinical atherosclerosis.

Aim: to determine the association between being born SGA and CIMT, a measure of atherogenesis and to investigate metabolic risk factors which impact on CIMT in obese children.
