Challenges in Differentiating Between Solitary Rectal Ulcer Syndrome and Inflammatory Bowel Disease in the Pediatric Population
Bibliographic record
Abstract
Solitary rectal ulcer syndrome (SRUS) is a benign rectal disease that is rare in pediatric populations due to its underdiagnosis and misdiagnosis in children. It is often misdiagnosed as malignancy, Crohn’s disease, and ulcerative colitis due to its wide and varying clinical presentations. Both SRUS and inflammatory bowel disease (IBD) can present with rectal bleeding, constipation, diarrhea, and abdominal pain. Furthermore, macroscopic ulcers and inflammation can be seen in both diseases, making it difficult to diagnose without a biopsy. We present two cases in the pediatric population whose diagnoses of SRUS were delayed because the symptoms and macroscopic findings initially supported the differential diagnosis of IBD. These cases emphasize the difficulty and importance of differentiating between IBD and SRUS, and should encourage practitioners to include this differential diagnosis earlier on to improve diagnostic accuracy and begin implementing effective treatment. This can eventually decrease overall treatment time, unnecessary surgeries and diagnostic testing, and increase the emotional reassurance of the benign nature of the disease.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
