Backwash ileitis in ulcerative colitis: Are there MR enterographic features that distinguish it from Crohn disease?
To reveal the MR enterography (MRE) findings that distinguish backwash ileitis (BWI) from terminal ileitis due to Crohn's disease (CD) and to determine the usability of barium studies manifestations (ileocecal valve (ICV) gaping, terminal ileum dilatation) in MRE for the diagnosis of BWI in ulc...

| description | To reveal the MR enterography (MRE) findings that distinguish backwash ileitis (BWI) from terminal ileitis due to Crohn's disease (CD) and to determine the usability of barium studies manifestations (ileocecal valve (ICV) gaping, terminal ileum dilatation) in MRE for the diagnosis of BWI in ulcerative colitis (UC) patients by pointing at the diagnostic performance of these imaging findings.
The study population consisted of patients who were diagnosed as ulcerative colitis (UC), and underwent 1.5 T MRI between August 2011 and November 2017 to rule out small bowel involvement. The matched controls were comprised of Crohn’s patients examined at the same period. Ileocolonoscopic/ histopathologic findings were accepted as reference standard. Mural/extramural changes in bowel segments, ileocecal valve (ICV) gaping, terminal ileum dilatation, restricted diffusion and anatomical extent of involvement were evaluated. In UC patients, the association between ICV gaping and terminal ileum dilatation and BWI was assessed by χ2 test. The diagnostic accuracy of these two findings in BWI was determined.
Sixty patients were included in the study (30 UC; 30 CD; mean age, 43 years in both groups). Ileocecal valve gaping and terminal ileum dilatation were significantly more frequent among BWI patients (p |

Sixty patients were included in the study (30 UC; 30 CD; mean age, 43 years in both groups). Ileocecal valve gaping and terminal ileum dilatation were significantly more frequent among BWI patients (p < 0.001) in UC. Patients with BWI showed a higher rate of pancolitis (88.9%). Median terminal ileum wall thickness was found to be significantly greater in patients with CD (p < 0.001).
In patients with definite diagnosis of UC, ileocecal valve gaping and terminal ileum dilatation suggest the development of BWI. However, these findings cannot be use to differentiate cause of terminal ileitis in patients with unconfirmed diagnosis and do not give reliable information about the causative factor of ileitis.</description><identifier>ISSN: 0720-048X</identifier><identifier>EISSN: 1872-7727</identifier><identifier>DOI: 10.1016/j.ejrad.2018.11.027</identifier><identifier>PMID: 30599862</identifier><language>eng</language><publisher>Ireland: Elsevier B.V</publisher><subject>Adolescent ; Adult ; Aged ; Backwash ileitis ; Colitis, Ulcerative - complications ; Colitis, Ulcerative - diagnostic imaging ; Crohn Disease - diagnostic imaging ; Crohn Disease - pathology ; Crohn's disease ; Diagnosis, Differential ; Female ; Humans ; Ileitis - complications ; Ileitis - diagnostic imaging ; Ileitis - pathology ; Ileum - diagnostic imaging ; Ileum - pathology ; Magnetic Resonance Imaging - methods ; Male ; Middle Aged ; MR enterography ; Reproducibility of Results ; Retrospective Studies ; Ulcerative colitis ; Young Adult</subject><ispartof>European journal of radiology, 2019-01, Vol.110, p.212-218</ispartof><rights>2018 Elsevier B.V.</rights><rights>Copyright © 2018 Elsevier B.V.
