Abstract

fetched live from OpenAlex

Left paraduodenal hernias, an abnormal protrusion of abdominal organs through a peritoneal defect into the fossa of Landzert, are a rare cause of small bowel obstruction. We present the case of a 21-year-old man with intermittent abdominal pain over several months. Diagnostic laparoscopy confirmed a left paraduodenal hernia. The hernia was reduced, and the fossa of Landzert was left widely open. This condition presents a diagnostic challenge, as symptoms are non-specific and imaging may appear unremarkable. Prompt diagnosis is essential to avoid complications such as strangulation and ischemia. Unlike conventional approaches, our surgical strategy involved enlarging and intentionally leaving the hernial defect open-justified by anatomical and pathophysiological reasoning. At 21-month follow-up, the patient remained symptom-free. This case highlights the importance of maintaining a high index of suspicion in similar clinical presentations and proposes an alternative surgical technique for managing this rare internal hernia.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
