Objectives:
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.
Clinical Significance:
Our findings may aid in choosing the appropriate type of forceps for intestinal biopsy.
