Acute appendicitis causing small bowel obstruction: a rare cause of mechanical obstruction
Bibliographic record
Abstract
Small bowel obstruction (SBO) is a common cause of acute abdominal pain, typically resulting from adhesions, hernias, or malignancy. Appendicitis is a rare etiology of mechanical SBO, with less than 50 cases documented in the literature. We report the case of a 66-year-old woman who presented with severe abdominal pain and vomiting. Computed tomography imaging revealed a closed-loop SBO with two transition points in the right lower quadrant and associated mesenteric congestion. Although the appendix appeared unremarkable on imaging, diagnostic laparoscopy identified an inflamed appendix forming a band encircling the small bowel, resulting in mechanical obstruction. A laparoscopic appendectomy was performed, with complete resolution of the obstruction. This case highlights a rare but important cause of SBO and emphasizes the role of early surgical intervention and diagnostic laparoscopy in identifying unusual intra-abdominal pathologies.

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.
