P24.03: Prenatal diagnosis of recto‐uterine fistula: a case report
Bibliographic record
Abstract
A 31 year-old woman, gravida 2, para 1, was referred at 30 4/7 weeks of a semingly uneventful pregnancy for large bowel dilation noted on ultrasound. She had no past medical history. In our center, ultrasound revealed macrosomia (above 99th percentile) bilateral hydronephrosis, multicystic ascites, microcephaly, duplication and distension of vagina and uterus. Fetal echocardiography demonstrated a complex cardiac malformation. Upon these findings, the patient elected for termination of pregnancy. On macroscopic evaluation, the fetus was a female weighing 1966 g. Cardiac examination showed significant right ventricular and pulmonary artery hypoplasia, stenosis of the pulmonary valve and atresia of the tricuspid valve with resulting dilation of the right atrium. The left ventricule and ascending aorta were remarkably dilated. Abdominal examination revealed multifocal intestinal adhesions suggesting peritonitis as well as complete anal agenesis and a resulting megarectum. A communicating fistula was noted between the rectum and a very dilated uterus. The fistulous tract ended at the level of a uterine septum which separated the uterus in 2 symmetrical cavities. Septal rupture was noted and the uterus contained traces of meconium. Fallopian tubes were dilated. Agenesis of the cervix and the proximal 2/3 of the vagina were noted. Bilateral hydronephrosis and slight ureteral dilation were found. To our knowledge, this is the first reported case of a terminal fistulous tract between the rectum and uterus.

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.
