Effects of dehydration time and staining technique on microscopic diagnosis of colitis

<p>ABSTRACT</p><p>In the western world colitis is a common chronic disease and in Sweden the prevalence is around 1%. If a patient has bloody diarrhea it is probably ulcerative proctocolitis or Crohn’s disease, whereas if the diarrhea is watery, it is microscopic colitis. For a diagnosis, the patient has to do a colonoscopy and a colonic biopsy sample has to be taken. The biopsy sample will be sent to a laboratory for sectioning, staining and microscopic analysis.</p><p>In this study we compared the effects of short and long dehydration time of the sample before the sectioning. We also compared staining with Alcianblue/Van Gieson and Van Gieson alone.</p><p>Our results showed that a short dehydration time was a milder treatment and made it easier to section the biopsy sample. The comparison of the two methods was unsuccessful because the staining with Alcianblue/Van Gieson failed.</p>
