Synchronous Onset of Two Complications in Colon Cancer: A Case Report
Bibliographic record
Abstract
As one of the most frequent malignancies in the world's population, colorectal cancer is also associated with its complications (perforation, obstruction and bleeding). Their incidence is common (2.6-50%), but synchronous occurrence of two of them in a patient is a rare condition and it is reported in small series or as a case report in the literature. We present a case of the descending colon cancer in a female patient that presented with perforation on tumor site with consecutive retroperitoneal and lumbar abscess and simultaneous presentation of large bowel obstruction. The patient was admitted and operated the same day, the abscess was opened and drained and bowel resection was performed with colostomy creation. The postoperative recovery was uneventful and the patient was discharged on postoperative day 10. Due to the high morbidity/mortality in cases of colon cancer emergencies, Hartman's procedure is often a reasonable option. Timely diagnosis of the colon cancer can reduce the complication rate of the disease worldwide.

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.
