| Abstract |
Solitary rectal ulcer syndrome (SRUS) is sufficiently uncommon that the clinician or general pathologist may lack familiarity with the disorder and may confuse it with other inflammatory bowel diseases. To evaluate the role of collagen staining in facilitating the differential diagnosis of SRUS, an initial open review was undertaken on 1672 consecutive patients whose 4780 colorectal biopsies were stained with H&E with added saffron to demonstrate collagen. Excess mucosal collagen was present in 39 (2.3%) of these patients. Twenty patients with a diffuse excess of mucosal collagen in biopsies from rectal ulcer margins or from otherwise abnormal rectal mucosa had SRUS; in the remaining 19 patients, excess mucosal collagen was focal (seven ischemic colitis, five collagenous colitis, three adenocarcinoma, and four chronic idiopathic ulcerative colitis). Diffuse excess mucosal collagen never was seen in idiopathic inflammatory bowel disease (128 Crohn's colitis and 446 ulcerative colitis). Blinded reviews then were performed on rectal biopsies from 33 patients with a variety of diagnoses (14 SRUS and 19 controls). Diffuse excess collagen by saffron staining was consistently observed in SRUS but was absent in all 19 controls. Additional blinded reviews were carried out because the collagen staining pattern in ischemic colitis, although focal, could potentially be confused with SRUS. It was possible to differentiate these two diseases blindly from one another by using additional histologic criteria (14 SRUS and 12 ischemic colitis). We conclude that the demonstration of a diffuse excess of mucosal collagen in rectal biopsies facilitates the diagnosis of SRUS and differentiates it from idiopathic ulcerative colitis and Crohn's disease, with which SRUS is often confused, and other inflammatory bowl diseases.(ABSTRACT TRUNCATED AT 250 WORDS) |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 August 2019.
All research outputs
#7,917,073
of 23,854,458 outputs
Outputs from Digestive Diseases and Sciences
#1,379
of 4,304 outputs
Outputs of similar age
#4,051
of 14,454 outputs
Outputs of similar age from Digestive Diseases and Sciences
#5
of 7 outputs
Altmetric has tracked 23,854,458 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,304 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.8. This one is in the 43rd percentile – i.e., 43% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 14,454 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 7 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
