Median Arcuate Ligament Syndrome: Management and Literature Review
Bibliographic record
Abstract
Pain, nausea, vomiting, weight loss, diarrhea, and fatigue are common symptoms of several upper gastroenterological illnesses. However, the presence of unexplained recurring postprandial abdominal pain and vomiting increases the possibility of median arcuate ligament syndrome (MALS). MALS is an uncommon illness characterized by postprandial vomiting, abdominal pain, and weight loss. The compression of the median arcuate ligament on the celiac trunk and/or its surrounding celiac nerve plexus may explain this disease phenomenon. Comprehensive workup for other etiologies may be unrevealing except for the compression of the celiac trunk identified in imaging studies and, perhaps, occasional arterial flow rates in sonography studies in some severe cases. Due to the overlapping symptoms of upper gastroenterological disorders, misdiagnosis may be widespread. Therefore, it is essential to consider MALS while examining a patient with upper gastrointestinal disease. In this case series, we present two cases of MALS with similar clinical trajectories and differences in diagnostic techniques.

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.
