<scp>P</scp>11.19: Closing gastroschisis: a case report with unusual antenatal ascites and literature review
Bibliographic record
Abstract
Gastroschisis is the most common abdominal wall defect affecting 1/2000-1/5000 pregnancies. We describe a case of antenatally diagnosed gastroschisis with the unusual appearance of fetal ascites. This finding led us to suspect a case of closing gastroschisis. A 35 year old woman, gravida 5, para 3, with no relevant history, was referred to our prenatal centre at 13 + 6 weeks following diagnosis of typical gastroschisis. Imaging at 18 weeks revealed fetal ascites with stable gastroschisis. Continued increase in ascitic volume as well as progressive hyperperistaltic intra-abdominal bowel dilatation was seen up until 26 weeks and subsequently collapsed. Diaphragmatic elevation due to increased ascites and polyhydramnios were seen at 29 weeks. Two paracenteses of the ascitic fluid were performed at 29 and 31 weeks. No change of extra-abdominal bowel was noticed during the successive scans with normal mesenteric perfusion. A 2.5kg girl was born vaginally at 34 + 2 weeks following preterm labour. At birth, the characteristic gastroschisis deficit was completely closed around the superior mesenteric vessels with the small intestine and ascending colon extra-abdominal. Surgical exploration revealed two intestinal atresias. A proximal jejunostomy and mucus fistula were created. Intestinal continuity was reestablished at 4 weeks of life. After a complicated hospital stay she discharged from the hospital at 4 months of life. The spectrum of closing gastroschisis is rare and can be associated with multiple complications and poor outcome.

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.
