Diagnostic yield and economic implications of endoscopic colonic biopsies in patients with chronic diarrhoea.
Colorectal Disease, 04/25/2012
Hotouras A et al. – In unselected patients with chronic diarrhoea and macroscopically normal mucosa, random colonic biopsies have a low diagnostic yield and incur a high cost. Continued research for predictive markers to improve patient selection for targeted biopsies is needed to develop a cost–effective investigative algorithm in chronic diarrhoea.
