Analysis of duodenal biopsies with dissecting microscopy is an unsophisticated method that, however, provides useful information in cases of frank villous atrophy. In the last 15\u2005years, we have always analysed duodenal biopsies with dissecting microscopy before sending them to the pathology department for histology. If the results of dissecting microscopy and traditional histology were comparable, we feel that would be strong evidence that grading of the histological lesion would be unnecessary if not pointless in the everyday diagnosis of enteropathies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The clinical notes of all 2075 patients undergoing duodenal biopsy between September 1999 and June 2015 were retrospectively analysed.
