Clinical characteristics and outcome of fistulizing Crohn's disease: One single‐center experience in Taiwan
Bibliographic record
Abstract
Crohn's disease (CD) is characterized by chronic and/or relapsing immune activation and inflammation within the gastrointestinal tract. Approximately 35% of patients with CD are complicated by fistulae. However, little is known about the incidence and natural history of fistulizing CD in Asia, especially enterocutaneous fistulae (ECF). In this study, we aimed to investigate the clinical course and outcomes of patients with fistulizing CD. We performed a retrospective analysis using the database of Chang Gung Memorial Hospital to analysis the clinical characteristics, clinical course of CD, gender, age, medical and surgical treatment, complications, and long‐term outcomes. From January 1989 to November 2016, 97 patients were enrolled (73 males and 24 females) with a median age at diagnosis of CD of 32 years (average 36.28 ± 15.84 years). All of the patients were classified by Montreal classification. Montreal classifications A2 (age 16‐40 years; n = 56, 57.7%), L3 (ileocolonic type; n = 47, 48.5%), and B1 (nonstricturing and nonpenetrating type; n = 43, 44.3%) were the most common phenotypes. ECF occurred in five patients (5.1%), enterovaginal fistula in three patients (3.1%), and enterovesical fistula in two patients (2.0%). The duration of CD before the onset of ECF was 3.9 years, enterovaginal fistula was 2.5 years, and enterovesical fistula was 5 years, and most of the patients complicated with a fistula required surgical treatment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
