Indicators of volatile fatty acids for differential diagnostics of nfected of pancreatic necrosis complicated by retroperitoneal phlegmon.

The aim of the study was to assess the informative value of volatile fatty acid parameters for the differential diagnosis of infected pancreatic necrosis (IPN), complicated by retroperitoneal cellulitis. The work was based on the results of examination and treatment of 44 patients with infected pancreatic necrosis. The analysis of concentrations of volatile fatty acids: acetic, propionic, butyric and isovalerianic was carried out on a Kristallux-4000 automated gas chromatograph with an HP-FFAP capillary column and a flame ionization detector. The indicators of acetic acid and the amount of volatile fatty acids were statistically significantly higher in patients with infected pancreatic necrosis with total retroperitoneal phlegmons in comparison with the indicators of volatile fatty acids in patients with infected pancreatic necrosis with paracolic phlegmons and in comparison with indicators of volatile fatty acids in patients with infected pancreatic necrosis phlegmons. The indicators of acetic acid and the amount of VFA can be used as additional criteria for the differential diagnosis of IPN complicated by phlegmons of the retroperitoneal tissue.
