An Unusual Cause of Mesenteric Ischemia of the Small Intestine: Jejunal Neuroendocrine Tumor
Bibliographic record
Abstract
Small intestinal neuroendocrine tumors are rare gastrointestinal malignancies (< 0.5% of all cancers). Complications at presentation include bleeding, abdominal pain, and bowel obstruction; small bowel ischemia and bowel necrosis are rare. A 63-year-old patient was referred from a rural hospital to Acute Care Surgery with bowel obstruction, and arrived in septic shock. He was resuscitated, diagnosed with mesenteric ischemia, and underwent an exploratory laparotomy which identified an internal hernia (which was released), and small bowel ischemia and necrosis which were resected. The incidence of acute mesenteric ischemia < 0.2% of all acute surgical admissions. Nonocclusive mesenteric ischemia accounts for 20% of all etiologies and was evident in this case. The superior mesenteric artery pulse was clinically palpable and there were no signs intraoperatively of venous stasis at the root of the mesentery. Pathology confirmed multiple small bowel mesentery neuroendocrine tumor nodules. Surgical resection remains the mainstay of 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.
