Case report: Sigmoid strangulation from evisceration through a perforated rectal prolapse ulcer – An unusual complication of rectal prolapse
Bibliographic record
Abstract
INTRODUCTION: Rectal prolapse occurs particularly in elder females and presentation can sometimes lead to complications such as strangulation and evisceration of other organs through the necrotic mucosa. PRESENTATION OF CASE: This is a case of a 61 year-old female with rectal prolapse complicated by rectal perforation through which a segment of sigmoid colon eviscerated and became strangulated. This patient initially presented with sepsis requiring ICU admission, but fully recovered following a Hartmann's procedure with a sacral rectopexy. DISCUSSION: Complications of rectal prolapse include incarceration, strangulation, and rarely, perforation with evisceration of other viscera requiring urgent operation. This report provides a brief overview of complications associated with rectal prolapse, reviews similar cases of transrectal evisceration, and discusses the management of chronic rectal prolapse. CONCLUSION: Prompt surgical consult is warranted if any signs or symptoms suggestive of complications from prolapse are present.

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.
