A Rare Case of Sigmoid Intussusception due to Sigmoid Diverticula in a Patient with Concomitant Extensive Small Bowel Diverticula
Bibliographic record
Abstract
Small intestinal diverticula is a rare occurrence, and their surgical management remains controversial due to the lack of a recognized classification system. Complications such as perforation and obstruction are treated surgically. Their etiology remains nebulous but theories such as damage to the Auerbach’s nerve plexus have been advanced as a possible cause. The concomitant presence of a sigmoid intussusception due to diverticular disease in the same patient is truly a rare occurrence. The vast majority of colonic intussusception is due to malignancy and a benign etiology remains elusive. The reported cases of benign causes include a lipoma and benign lymphadenopathy. We believe this to be the first such case report of a colonic diverticulum causing an intussusception. Despite an exploratory laparotomy of less than sixty minutes, the patient demised in the intensive care unit following an occipital lobe stroke. We believe this case of sigmoid intussusception with concomitant small intestinal diverticula to be the first such case report of its kind in English-language scientific publications.

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.
