The role of ultrasound (US) is extremely important in the early detection (diagnosis) of peritoneal catheter tunnel infection (TI) in subjects with catheter exit-site infection (ESI), also for the therapeutic follow up of tunnel infection and in particular to evaluate (assess) the prognosis in cases of deep infection. ESI is the major cause of peritonitis because it is associated to bacterial migration and overgrowth which involve deep cuff and then the tunnel. The use of US is now widely recognized, it allows the identification of persistent foci as hypoechoic pericatheter areas and specially to evaluate response to antibiotic therapy. Between January 2012 and Dicember 2015 eight patients with infectious complication (ESI-PERITONITIS) underwent to US- Color Doppler examination of peritoneal catheter.
This study describes how peritoneal catheter follow up associated to color Doppler can prevent peritonitis ESI correlated, because the use of color Doppler allows to differenziate exudative areas from those areas of intense vascular proliferation, suggesting timing for cuff shaving surgery and external cuff removal, to prevent infectious propagation, potential peritonitis, as well as to save catheter.
