Cure8 research brief
The study suggests TPUS can detect persistent sonographic features in many pediatric perianal fistulas even after MRI shows radiologic healing, indicating TPUS may add information about healing dynamics and treatment response.
Pediatric gastroenterologists, pediatric radiologists, clinicians managing perianal Crohn disease, parents/caregivers of children with perianal fistulas, and imaging researchers.
This retrospective series of 24 children (45 fistulas) found that 60% of fistulas remained detectable by TPUS despite complete healing on MRI. Persisting sonographic findings showed measurable improvement: reduced diameter, decreased vascularity, resolution of pus and surrounding inflammation, loss of the layered internal pattern, and increased anisotropy.
The authors conclude TPUS provides complementary, multiparametric information about treatment response but note these persistent sonographic signals need validation in larger, longer studies.
This is a retrospective, single-cohort imaging study reported in an abstract/full-text on PubMed. Findings describe imaging correlations (TPUS vs MRI) and do not by themselves establish changes to treatment or prognosis. Further validation in larger, prospective cohorts with clinical outcomes is needed.

Perianal fistulas are a common and morbid complication of Crohn's disease in children; a reliable, less burdensome imaging tool could help assess severity and monitor response to therapy more often than MRI.
Accurate imaging of perianal fistulas guides treatment decisions (medical vs surgical/drainage) and planning. If non-contrast MRI performs well, it could be used when contrast is unsafe or to speed up scans while still...
Accurate, radiation-free imaging at the point of care can speed diagnosis and management of strictures, abscesses, and fistulas in Crohn’s disease. Improved ultrasound techniques may help determine who needs surgery or...
