title: Comparison of routinely used intestinal biopsy forceps in dogs: an ex vivo histopathological approach.
abstract: OBJECTIVE
  To compare the quality of duodenal and ileal samples obtained with different biopsy forceps.
  
  
  METHODS
  Fifteen dogs were included in a prospective ex vivo study. After euthanasia, the duodenum and the ileum were sampled with four different forceps and evaluated according to a standardised scoring system. The biopsy forceps evaluated had alligator jaws or cups with smooth edge with or without a needle.
  
  
  RESULTS
  The global quality of the biopsies was better in the ileum that in the duodenum regardless of the biopsy forceps. Biopsy forceps with smooth edge including a needle resulted in fewer artefacts than biopsy forceps with smooth edge but no needle in both sites and those with alligator jaws without a needle provided deeper biopsies than those with smooth edge without a needle only in the duodenum. There was no effect of the biopsy forceps type on the size of the biopsies.
  
  
  CONCLUSIONS
  Our findings may aid in choosing the appropriate type of forceps for intestinal biopsy.
